sleep² sleeptracker & analysis

Paid for the PRO subscription, but it didn’t contain all of the metrics described. Additionally, the UI is quite poor for comparing data between nights and zooming into specific nightly data. And the final nail in the coffin resulting in cancelling subscription in under a week is no error detection or restart capabilities. I had nights where the device I wore (Polar H10) had a brief (5 second) Bluetooth signal loss, due to rolling onto my stomach while asleep. This resulted in Sleep2 ceasing all recording activity and dumping the ENTIRE night’s data.

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.

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.
