sleep² sleeptracker & analysis users say on Google Play
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.
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.
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.
Two Problems: 1) The way the UI is set up is bad, since it doesn't communicate clearly whether the sensor is connected or not, and I've lost sleep data because of it! Make a simple red/green sensor connectivity sign both before going to sleep & before waking up! 2) (IMPORTANT!) App only allows one sleep session per day, so my one-hour long powernaps in the afternoon can't be recorded. :( Annoyingly, the app tells me only *after* the powernap that there is a "Tagebucheintrag" already for the day.
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.
