Help. Error is barring me from recording my sleep: GoException: redirect loop detected /sleep => /user-settings/true => /user-settings/true => /sleep. Also, often after putting in my sleep factors and hitting save, I'm taken back to the home page instead of the starting the sleep sequence.
Developer response
Thank you for your feedback, Jonathan! We are sorry, this issue occurred for some users after the last update. Updating to version 3.0 and reinstalling the app can resolve it. Additionally, we'll check the factor bug as well! If you face any problems not or in the future, please contact us directly at [email protected] – we would love to help!
love this app
Developer response
Thank you so much - and we love hearing that:) If you ever have feedback, questions or face issues, feel free to reach out via [email protected]!
nice app but *way* too expensive. and the free plan does not offer much i sight into sleeping :(
Developer response
Thank you for your feedback, great you like the app! We understand the price may seem high at first. It reflects the effort behind our science-based sleep analysis and therapy, which relies on high-resolution raw data as well as cognitive behavioral therapy. Additionally, we're continuously working to improve the app.
It's good as long as the sensor data gets read and processed. Every so often even with the sensor on, the data does not get read and no reason or even partial results are given, you lose the whole nights data.
Developer response
Thank you for your feedback! It sounds like the sensor may not have been properly connected or was possibly in use by another app at the same time. To avoid data loss, please ensure the sensor is started manually (not via Polar Flow) and used exclusively with Sleep². Feel free to contact us at [email protected] - we’d love to help!
Good and accurate sleep tracker
Developer response
Hi John! Thank you for your kind feedback :) We're happy to hear that you're satisfied with the accuracy of Sleep². If you ever have questions, suggestions or issues, feel free to reach out to us at [email protected] – we’re always happy to support!
One of the best apps. Highly recommend. Is developed by actual sleep researchers!!!! Kudos!
Developer response
Thank you so much for your amazing feedback, Alex! We're truly honored – and yes, the app is developed by sleep researchers to ensure scientific accuracy. Your support means a lot to us.
This app is a waste of money since it never works!
Developer response
Dear Kenneth, thanks for your feedback. But please help us understand what does not work. We are there for you at [email protected]. Your sleep² team.
Top engga kalah sama sleep trackernya apple watch
Developer response
Dear Ari! Thanks for your feedback. Indeed giving sleep lab data I can tell you that we are not only NOT inferior to apple watch but actually quite a bit better when it comes to sleep staging in the 4 classes: Wake, Light Sleep, Deep Sleep, REM. What you need are sensors specialized just on HRV measurements and being close to the hard & great AI.
I buy Polar H10 and subscribd this app based on the accuracy measured by Quantified Scientist guy. It's nice and motivating to be able seeing the progress you've made to your sleep. The app also informative enough to educate us on how to fix the bad aspect of our sleep. Bryan Johnson also sparked a motivation to fix my terrible sleep. I see immediate results of having higher energy, easy to wake up refreshed naturally, within under a few weeks of sleep earlier & eat further from sleep.
Developer response
Hi Diori! Thanks for your feedback. Indeed tracking with H10 or Verity Sense gives you the best results in terms of tracking accuracy. The "intervention" itself is no rocket-science and we know that. But you know what. It should be "boooooring" and not to exciting because it is all about routines and winding you down in the evening ;-) Sleep² well!
Using it for a week. Pretty good on the tracking and summarising part. Getting to pair a polar verity is tricky but once done it is seamless.
Developer response
Hi Hardik! Thanks a lot for your feedback. We are happy that you like the sleep² App. For the Verity Sense we know that some user seem to encounter problems in the beginning. But following exactly the instructions - like coupling VS only in the App but NOT the bluetooth settings, or activating location services for BLE to find you - usually works:)
If you have polar H10 then it's a great app.
Developer response
Danke, das sehen wir bei sleep² auch so ;-)
Wish it was possible to export sleep cycles to google fit, good accuracy and insights otherwise
Developer response
Dear Gianluca! Great that you like sleep². Write us and we can discuss about an individual report of your data if this is of specfic interest for you. Your sleep² team.
Tooo expensive. And the free version does not show you enough to even make it worth using it. Devs think people can afford to pay subscribtion for everything nowadays. 20/month is crazy.
Developer response
Dear Fitim, thanks for your feedback. We are sorry to see your review but would like to help you understand better. Sleep² is not just yet another fitness product also including sleep. We developed an App with an armada of scientist that allows sleep staging in real sleep lab quality and sleep coaching like recommended by international societies.
1: expensive, 2: detecting sleep stages is good, 3: no way to verify how changes in sleep hygiene affect sleep, because there is no factor to sleep quality improvement detection, and there is no option to export data to make such detections manually. this is actually my biggest complaint. hope it will change in future. 4: has multiple major bugs. 5: App has high potential and I look forward for improvements
Developer response
Dear KM! Thanks for your Feedback. Indeed according to our analyses sleep² classifies with sleep-lab like accuracy in all 4 sleep stages including wake. Any kind of sleep factor can be added by yourself in the app. Starting Q1/2025 we will then show you the results for them. Also feel free if you need some raw data, we may be able to help;-)
The app is very intuitive to use and seems more accurate than other sleep trackers.
Good intuitive app so far. I had no idea I was sleeping so badly so it's great to get the insight. Hopefully this app will help me change my bad sleeping habits and improve my sleep function! Con: expensive - I don't see myself using this for more than maybe 4 months as the pricing is too high
Nice.
Die App hat mir super wichtige Erkenntnisse über meinen Schlaf geliefert und mir Ansatzpunke gegeben, wie ich meine Schlafqualität verbessern kann. Absolute Empfehlung! Wichtig zu wissen ist, dass man für eine verlässliche Schlafanalyse noch einen Pulsmesser zB von Polar Verity Sense braucht. Das Verbinden zwischen Pulsmesser und App funktioniert dann ganz einfach, und schon kann es losgehen.
Sehr schöne App, die Auswertung meiner Schlafdaten gefällt mir.
Developer response
Das freut uns!! Und es kommt noch mehr. Demnächst werden wir auch alle Schlaffaktoren die du auswählst gut aufbereitet zurück melden sodass du weißt wie sich ein bestimmter Faktor auf deine Schlaf- und Herzdaten auswirkt. Stay tuned!
Great sleep phase tracking accuracy, but very little data and poor presentation. The sleep therapy stuff is more comical than anything else - the weakest and most poorly done I've seen anywhere. Also no landscape mode.
Developer response
Hi Oliver, thank you for your feedback. Feel free to write to us at [email protected] with any suggestions you have, as we take user feedback very seriously! The sleep therapy is not a random compilation but follows the sleep medicine guidelines for improving sleep (CBT-I) 100%; however, we are also working here on innovative extensions & updates!
The biggest problem for me is that 90% of the nights it shows my awake time as 0, which is impossible. I am using verity sense and I dont know how it gets it so wrong. Also, I dont like big blurred cards reminding that you have to buy a subscription, you can make it more subtle. The first main screen seems use less, and the app does not allow to change the start screen. So for me it makes no sense for me to buy a subscription or even continue using the app which gets the main info(sleep) wrong.
Developer response
Hi Roman, danke für dein Feedback. Beachte bitte dass die Wachzeit die du siehst nur Phasen länger als 2 Minuten beinhalten, denn das sind die Wachphasen die die meisten Menschen auch bewusst wahrnehmen. In deiner Gesamtschlafzeit ziehen wir aber natürlich alle kurzen Wachepochen ab. Falls dir das nicht hilft schreib uns gerne auf [email protected]
Excellent app.
Developer response
Thank you so much for your positive feedback! We're glad you're enjoying sleep² and are happy to be a part of your personal journey to healthier sleep.
I really wanted to like this because of the accurate sleep stage tracking but found it wasn't a fit. I found wearing my Polar H10 while sleeping uncomfortable and wondered if just wearing the H10 was negatively impacting my sleep. Also, I found the graphs not as good as Garmins, and the price too high. I see they finally added min HR and HRV which are good steps. I would like to see better graphs, reduced costs, and more features. If they do that, maybe I would try again with armband sensor
Developer response
Hi! Thanks for your feedback! We understand your concerns about pricing but please understand that the related research and development is substantial. However, we are constantly working towards new features and a new big update is around the corner. You will soon see all past hypnograms and HR graphs, factor feedback, etc. Please stay tuned!
25€ a month is ridiculous, at least tell the price before downloading it, at least people save some time.
Developer response
Thank you for your feedback! We understand your concerns about the price. Sleep² has been developed with a big tech and AI team at the University; Unfortunately, this comes with costs. We're constantly working to provide more valuable features and hope you find them useful in improving your sleep quality. So stay tuned already next week...
The app is terrible. Never seen worse UX. It's the first sleep app that does not auto detect sleep and you will need a week to understand how to even make it track anything. And that is after paying 20 EUR a month for no obvious reason. Just bad. I god scammed.
Developer response
Dear Christian, sorry to read that you are unhappy with sleep² as we put lots of effort in UX design. Sleep is actually better detected than in any other App - we published on that. Can you clarify what is the problem? E.g., getting longer "total sleep time" in the App than subjectively felt is a known fact and often related to "hyperarousal".
I really dislike this app. I am paying the full $20+ per month. The app is buggy and difficult to use. It is a constant struggle to use. It is so bad that it actually makes me lose sleep because I get frustrated and angry right before bed when I am supposed to be relaxing. Then for the big disappointment in the morning when after all that trouble and expense I still don't get my sleep number. I am canceling my subscription and I am out.
Developer response
Dear Bryon, sorry to hear that you have issues with sleep². But can you please help us to understand better what the problem is? We put a lot of effort so that sleep² has high usability and is easy to handle. Please tell us more at [email protected] and we see how we can help you specifically with the problems you seem to encounter. Best sleep² team
Great app for sleep tracking. Would like to see more devices that can work together with the app. Preferably huawei watches.
Developer response
Dear Zelijko! We took your advise very serious and recently released the ENGLISH version of the app. Sleep² now also comes with new features and you even can use your habitual smartwatch or sleep sensor with sleep² (if it shares its sleep data with GoogleFit). Please thus test and RATE US again. We are sure we are a few steps further by now.
App has plenty of issues and is not fun to use. Manual sleep training doesn't work, singn up with my insurance was complicated and audio for exercises is distributed by small interruptions. Don't recommend.
Developer response
We are sorry that you seem to have problems with sleep². Actually the flow into the App should be straightforward. Please write us ([email protected]) to understand where you had the problems and what you mean with interruptions in the audios or the "manual sleep training" does not work. This is new to us but we are there to help!
Unacceptably buggy
Developer response
Dear Andrew, being a university spin-off sleep² is coming with the highest quality standards in algorithms as well as App development. Please tell us more if you encounter problems at [email protected]. We take user responses very serious and continously are improving the App and extending available features. Please thus re-consider your rating...
1) You'll need to buy a Polar sensor for 65 euros before you can even use the free option. 2) This app has 5k downlands but no reviews - why is that? U/inst...
Developer response
Hello Chris! Thanks for your answer. Buying a sensor is NOT needed. You can use sleep² also with a sleep diary, or your smartwatch/sensor (via GoogleFit) and you can of course use our FREE VERSION for an unlimited time. There you can do everything but features will be restricted. Feel free to contact us and re-consider you rating if this helps!
I tried sleep2 because of the recommendation, but can't really say anything about it because all the good things are hidden behind a 25eur/month paywall. It's a lie that there is a free trial/version, because you pay for it with your data and get for that some very basic data and numbers without any individual recommendations (something for what this app was recommended for). 25 eur/month is actually a good thing - I might slip ant try it blindly for 9.99, but 25? Wake up from your fantasy.
Developer response
Hi Paulius! Actually you can test the App for FREE. Please consider that sleep² is an evidence-based product not comparable to fitness Apps. **And as an UPDATE for you: From today you also see your heart rate and heart rate variability (HRV) in the App night by night indicating your recovery potential! ** Please check and rate us again!
impressive technology and very precise evaluation of the sleep patterns. The pro version is quite pricy though at 20 euros a month, it is unclear for me if it is worth that much. it could be improved with more guidance on what to do to improve sleep. for example with goals to achieve each day before getting to bedtime.
Developer response
Danke für die Rückmeldung. Das ist eine gute Idee. Wir arbeiten ständig an neuen Entwicklungen um das Schlaf-Coaching weiter zu verbessern. Es wird hier demnächst spannende neue Entwicklungen geben, z.B. zu den Schlaffaktoren die man Abends angibt spezielle Rückmeldungen zu erhalten wie diese konkret den eigenen Schlaf beeinflussen.
When are you planning on releasing an English version of the app?
Developer response
Hi William, thanks for your review! Since so many people are asking for the englisch translation, we are currently working on realizing this customer request :) In June/July we will be ready to publish the english version. We would be very happy if you could try out the app once again and let us know what you think?! :)
Can't see if it works until you subscribe. $23 /month/ costs a fitbit every 4 months. Does it work? Can't tell without subscribing. If it worked great, had a trial, and didn't cost more than oaura, sleep8, etc subscriptions ($10/ month would be high), would be 5*. Shows quality at 100%, which is impossible with waking up multiple times. Really need to find a useful sleep tracking app, sadly this doesn't appear to be it.
Developer response
Dear Chris, thanks for your review. Please write us at [email protected] and we look directly into the issues you seem to have. I am happy to help and find a solution with you. **UPDATE: From today you also see your heart rate and heart rate variability (HRV) in the App night by night indicating your recovery potential! ** Best Manuel from sleep²
Best app to track your sleep, forget about all android watches really useless, use this app with Polar sensor to get such high accurate reading for your sleep phases. Can't recommend it enough. Please keep it up and waiting to add more features to the free version, the current is good but I have high hopes. Thanks guys for this rewarding app
Developer response
Vielen Dank für die positive Rückmeldung! Es wird bald weitere spannende Entwicklungen in der App geben. Stay tuned! Und ja, die Schlaf-Messung macht uns besonders stolz und ist die einzige die tatsächlich an die Genauigkeit in einem Schlaflabor heran kommt und in den 4 Klassen (Wach, Leichtschlaf, Tiefschlaf, Traumschlaf) klassifizieren kann.
Will give this 5 stars due to The Quantified Scientist recommendations. Will update rating based on personal experience. Currently trying this on the Basic Plan and compare with my other sleep trackers. Should have offered some of premium trial at least
Developer response
Many thanks for your great review, Michael! We hope you like the app too:) With the BASIC version you can get to know the app and receive feedback on the most important sleep parameters. If you would like to try out the more detailed sleep analysis for your comparisons, you can upgrade to monthly Pro or have a look at our sleep training.
Now that the English version is finally out, I decided to subscribe. I really like the accurate results that I get with this using the Polar H10! It is actually very comfortable, and is a really cheap device which I can also use for activity tracking. It would be awesome if you could give us more insights into both our HRV, and the different stages. More details when pressing "sleep phases". Also, would be nice if you could switch the entire statistics tab to another day. Not just the latest day
Developer response
Hi Frederik! We have an update of specific interest to you. **From today you also see your heart rate and heart rate variability (HRV) in the App night by night indicating your recovery potential! ** Please CHECK IT OUT!!
Amazing app and amazing customer service. Now that they added English, the app is a legend. I like it so much that I'm writing this another 5 star review from my second account!
Developer response
THANK YOU, Mateusz for your positive review! We appreciate that you contacted us per mail and would like to thank you for the good communication, which helps us to continuously improve the app. Hope you'll have a good time with sleep2 for a long time to come :)
Why is it only in german??
Developer response
Hi! As we take user requests very serious we put a lot of effort in translating the App and exercises and recently released a fully English version of sleep². Please check it out and re-consider your App rating if this now matches your expectations.
Please add english language. Usable in german.
Developer response
Dear Alessandro, the English Version is online! Hope it meets your expectations! We constantly develop new features, so stay tuned and wait for our major updates in August.
What about English or some another in-app translation? I only see it in Deutch.
Developer response
Dear Vladan, the English version is now released and hopefully meets all your expectations. If this helps please re-consider if sleep² may deserve a better rating from you ;-)
Failed to pair with Polar H10 so can't even try it. Also could not find a way to change language to English so apparently that option doesn't exist? Edit: pairing started working, waiting for English version now. Subscription seems expensive. At least 1 month full trial would be nice when English is available. H10 is great for everything else but would be nice to also have support for some sO2 sensors (parallel with H10) like Garmin watches or similar to enable low sO2 / sleep apnea detection.
Developer response
Hi Markus, before you decide to buy the full version, you can get to know the app free of charge with the BASIC subscription. The ENGLISH version is now online, please check it out! If you still have problems please contact us and re-consider your App rating if we could improve to the better for you :-)
Really good except there's no English. Not an deal braker for me but for most people unusable. Really good data gathering tool.
Developer response
Thanks for your feedback - we're happy that you like our sleep statistics!!! Actually the app was intended for German-speaking countries, but since so many people ask for an English version, we are currently working on the translation and can't wait for the release in mid 2024 :)
I like the latest update that you can include age and gender!
Developer response
Vielen Dank, Pavlos:) Jetzt sind deine Schlafstatistiken noch mehr auf dich zugeschnitten - Wir freuen uns, dass dir diese neue Funktion gefällt!
I used the app in the free mode, and it really helped me understand how my sleep changes in relation to what life throws at me. I've learnt to anticipate how my sleep will be on a given day given what is happening, and what I can do to sleep deeper and longer. For me, the solutions that worked usually relate to physical activity and nutrition, and timing those things well. Bummer that it's only in German, but since I speak German, I had no problem with that :)
Developer response
Thanks for your positive feedback, Jonah! It's great to read that you can benefit so much from sleep² and how you appreciate the whole content. Good news for you: We are already working on the translation and are looking forward to publish the englisch version in mid-2024.
I assumed I would be able to use my smart watch (through Health Connect) to track my sleep. I was wrong. Either you own one of the two devices that this app wants you to buy or you have to track your sleep manually. No thanks. | Edit: To be fair, I cannot comment on the sleeping recommendations or potential improvements because I never got this far as I will not track my sleep manually if I already own a smart watch that does that for me. And I won't buy an extra device either...
Developer response
Dear Stevo! Sleep² is now available in English and we considerably improved the connection of other smartwatches and sensors for your convenience. You soon will also be able to import historical data. Crucial is that only accurate (!) sleep analysis allows for individual sleep coaching as in sleep². Please check it out and re-consider your rating.
No english, bummer wanted to use it looks promising
Developer response
Dear David, we took the user feedback very serious and now deployed an English version of the App. We also constantly work on other and new features in sleep² and would be super happy if you would test and RATE us again if these changes were to your convenience!
Worst app and waste of storage space
Developer response
We are sorry that you were unhappy with the previous version of sleep². We now released an ENGLISH version and added multiple new features. We thus would be very happy if you would test and rate sleep² again. If you have specific things you do not like don't hesitate to write us directly at [email protected].
Diese monatlichen Preise sind zum Lachen. Hätte mir das Gerät gekauft wenn das nicht so eine Abzocke wäre
Developer response
Hello, sleep² is now available in ENGLISH! Concerning the costs please bear in mind that sleep² was developed directly at the University of Salzburg with a team of sleep experts and mathematicians and that this most accurate sleep analysis plus sleep coaching on the market naturally has its price in development. Thus please test and rate us AGAIN!
Die App ist gut designed und liefert gute Ergebnisse. Die permanente Beantwortung von Fragen fand ich etwas nervig. Die Aufschlüsselung der Daten könnte etwas umfangreicher sein. Wenn ich zb schon einen Brustgurt trage, der den Herzschlag aufzeichnet, würde ich die Daten auch gern sehen. Alles in allem waren die Aufzeichnungen nicht viel anders als von meiner SmartWatch und der Preis ist hierfür einfach zu hoch als das ich für mich hier einen Mehrwert sehe.
Developer response
Hallo Chris, danke für deine Rückmeldung. Als Uni spin-off haben wir uns bei sleep² zur Aufgabe gemacht die genaueste Schlafanalyse mit den messgenauesten Sensoren anzubieten. Unsre wissensch. Evidenz findest du hier: https://www.sleep2.com/unsere-forschung. Nächtliche Herzdaten werden demnächst angezeigt. Tests und bewerte uns daher gerne NEU!
