Ratings and Reviews
Excellent. Better than whoop for sleep tracking
I was a whoop user for years and recently decided to try and look for an app that could give me a better HRV reading than the Apple Watch — without costing as much as whoop. And this is it! The app is great when paired with a polar strap (I use the H10) and what I like
The most is the very direct feedback the app gives me every morning about which aspects of my sleep I need to Improve and how.
I’ve tried other apps for this like garmin, whoop, gentle streak, and sleep cycle and this is by far the best one. Plus using a chest strap means I don’t have to charge another device to track my sleep.
The only thing I wish they would change is to allow the app to write sleep data to the Apple health app through HealthKit. The app
Doesn’t current do this which means I still wear my Apple Watch to bed (huge bummer) bc the data in sleep2 stays only in the app itself. But I contacted support and they answered me (super fast!) and told that should change soon.
Their support team seems great and I really appreciate how personable and detailed they were in their response to me. Excellent customer service.
Developer Response ,

We're thrilled to hear that sleep² together with your Polar H10 is giving you the clarity and feedback you were looking for, especially after trying so many other platforms. We appreciate your suggestion about Apple Health integration and highlighting the importance of data export. We are happy to confirm: it is already in development and will be available soon. Also, a big thank you for your kind words about our support team. We truly put a lot of care into every reply and it’s really encouraging when that’s noticed. Thanks for your trust and being part of the sleep² community :)
the most accurate sleep stage tracker
this company has done the hard scientific work to prove that their algorithm is the best available with published studies on their website. customer support is very responsive to suggestions.

Thank you so much for your kind words! We're thrilled that the scientific foundation and our commitment to support are appreciated. Your feedback motivates us to keep improving – thank you for being part of the Sleep² journey :)
Where are the graphs?
You can’t view past data in the form you get it from the “today” view. You can only view previous nights data in text form in the “diary”. The sleep graphs from previous nights just disappear into the Aether. Kind of a lackluster design. Even Garmin connect shows past nights sleep graphs.
Developer Response ,
Dear mfree77, we are sorry that some of the sleep parameter feedback you get is only available on the same day. But we take your feedback very seriously and we are working on an update where you actually can go back in time to see all your hypnograms.
By the way. All the data of your past you always find in form of line graphs when you click your sleep parameters in the statistic screen.
If you are eager to see your past hypnograms drop as a line at hello@sleep2.com and we will find a solution for you.
If this helps, please consider revising your rating. Otherwise write us how we can help you any further.
