★★★★★ What kind of a scam is this?
★★★★★ I'm sorry I spent money on this app; don't make the same mistake.
★★★★★ Today, charged $19.99 and no way to get my money back.
57 of the 1 and 2 star reviews.
★★★★★ it is good to see heart rate noise but the hours inaccurate often
★★★★★ I really want to like this app but there is something seriously wrong with it.
★★★★★ I have noticed that the time it shows I'm asleep is not correct. Example: I got up at 4:30am. At 5:55 am the app asked me if I was ready to start my day. It is not detecting whether I'm awake or sleeping.

16 of the 1 and 2 star reviews.
★★★★★ I'll probably try it again if/when there's a new version.
★★★★★ I've done the latest Apple update, I've uninstalled and reinstalled several times, as well as reset my iPhone.
★★★★★ UPDATE (in response to developer reply) so you're saying there's some other reason it's stopped working, but you can't guess what that might be.

★★★★★ Today, charged $19.99 and no way to get my money back.
★★★★★ It wouldn't be a huge deal but you can't edit the bad data that gets generated and have it stay (give it a couple minutes and it will vanish); to edit you HAVE to have a time asleep in a given range (despite it…
★★★★★ I suppose I will have to extrapolate the data to include my missing 2-3 hours of sleep.
13 of the 1 and 2 star reviews.

★★★★★ Phone and Apple Watch 8 Not syncing.
10 of the 1 and 2 star reviews.
★★★★★ Was working fine now it doesn't open.
★★★★★ Now the app continuously crashes Every time you even attempt to open it.

6 of the 1 and 2 star reviews.

★★★★★ No support available from what I can see.
6 of the 4 and 5 star reviews.
★★★★★ I don't care how it does it, I just need it to give me an accurate time for when I fell asleep, which it doesn't.
★★★★★ Wish it was a bit more accurate.
★★★★★ It works great and just gets better.
5 of the 4 and 5 star reviews.
★★★★★ I like nap bot Because it helps Apple Watches actually keep a record of your actual sleep and naps because the sleep part of the health app has to Have a sleep schedule and even if do t sleep it counts it During the…
★★★★★ It's helpful in many ways.
★★★★★ The sleep detection works automatically and I found it very useful.
4 of the 4 and 5 star reviews.
★★★★★ in the Picture the Calendar UI shows a history greater than 24 hours
★★★★★ The interface is very easy to use and looks nice.
★★★★★ I have a few things I look for in a sleep app: - good design - just tracks my sleep passively, doesn't set an alarm or drain battery - not insanely expensive
3 of the 4 and 5 star reviews.
★★★★★ I thought maybe the free trial was over so I subbed but nope.
★★★★★ I might just do the free trial to see what else this great app has !!
★★★★★ In my opinion the developer need to offer 30 days free, instead of 7 days, this will help them to learn about some bugs the app may have, and fix.
3 of the 4 and 5 star reviews.
★★★★★ Apple watches that are paired as a 'family share' would enjoy this app since you cannot use the Apple Sleep app on a 'standalone' apple watch.
★★★★★ Very informative and is actually fun to see the results even if mine are poor at times...

I like nap bot Because it helps Apple Watches actually keep a record of your actual sleep and naps because the sleep part of the health app has to Have a sleep schedule and even if do t sleep it counts it During the schedule so if you like to know true sleeping information this helps you know
I want to use this app for sleep duration plus checking for Sleep Apnea. But for some reason the Sleep Apnea only seems to work a couple of times a month.
Can’t remove app!!!
Does not track naps
