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.

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

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.

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.

1 extremely pricey 2 detected wakeup times are bad 3 detecting other sleep stages is good, 4 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. 5 poor help support. 6. at this point in time i strongly discourage from paying for this limited functionality app

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

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.

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.
