Ratings and Reviews
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.

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.
Don’t waste your money
This got a great review by Quantified Scientist, who has a YouTube channel that I have been watching for the last few years. I am so unimpressed with this is a sleep tracker and it can vary widely from my Oura ring which I’ve had for about four years and my Apple Watch. Interestingly, those two devices are generally pretty close but the Sleep2 is not even consistent. Unfortunately, I wasted $200. The app said I couldcancel it anytime, I guess naïvely I thought I would get my money back for the time I didn’t use instead. My subscription goes until December 2025. As the title of my review says, don’t waste your money.
Developer Response ,
Hi, we are sorry that you do not seem to he happy with sleep². I just can verify that we are doing constant tests against the PSG gold-standard usign EEG, EMG and EOG and that sleep² outperforms all other devices including Oura.
We wonder what may be the problem in your specific case. Please don't hesitate to write us at hello@sleep2.com and we try to help you immediately!
Also we are currently working on big changes and will improve the sleep diary, the use of sleep factors and their analysis as well as many other things...
Not impressed
App is very clunky. A lot of the data is the same and can be read on Apple health that is free. I attempted to use polar h10 sensor but always says there is an error with data. Other apps worked fine for sleeping. Not worth $22/month.
Developer Response ,
Dear user, given our scientific tests against the gold-standard in the sleep lab we can verify that our algorithms with Polar Sensors come with much higher accuracy than standard wearables (see tech reports in Topalidis et al., 2023a, 2023b). Polar H10 sensors should work fine and we have no other issues reported. Please write us directly at hello@sleep2.com and we help you immediately!
