## Sleep Time Reviews in United States

### ***** "Great sleep health app"
This app has helped improve my sleep more than any other sleep app
-- 20111234, 2023-10-07

### ***** "Long time"
I started using this app in April of 2014 and have used it almost every weeknight since then. I love the way it wakes me up. 

I wish I had a way to export all of the data over to my health app though. It only goes back so far.
-- Pizza Gut, 2023-09-11

### ***-- "No more heart rate function"
I used the heart rate function every morning. Following the last update it’s gone. Very disappointing.
-- wharrott, 2023-09-08

### ****- "Great app with a bug …"
I’ve been using this app for several years. It’s great.

When my phone is face down and the app is tracking my sleep, the screen turns off like it’s supposed to. But if I’m listening to music and increase the volume or skip the track, the screen turns on and won’t turn off again until I pick up the phone and put it back down. I’ve had many nights when this has run the battery all the way down. Please fix if possible. Thanks!
-- The Last Man 56, 2022-09-17

### *---- "Awful app"
App is not worth (even $2) after switching to iPhone from android I have been very happy. But something like a simple alarm that will override the phone volume is an issue… #EpicFail
-- EA612, 2021-10-24

### *---- "App keeps crashing"
Crashing and not saving data from overnight.
-- monkeyqueen13, 2021-07-21

### ***-- "Needs up-date"
I like what the app can do. What it says is that is is good for sleep problems. I haven’t found an app that notices when the phone is still to note how long it was still and ask it it was charging, away from patron or was it a sleep attack (an unintentional nap caused by narcolepsy). The app description sub-title says something about naps - you can’t read the rest of the description. This app also hasn’t been up-dated in over two years. 

I’m not willing to buy a subscription when there’s no consistent checking for up dates. 
Also, when it says in app purchases, it needs to be clarified what the other charges get you, maybe $1.99 gets you Ad-free? $4.99 gets you what? I get that $9.99 is for the monthly subscription & the $29.99 is for the yearly subscription. But why are both of those amounts on their twice? 

I just need a little more help. The app is very good though.
-- Progressin, 2021-05-13

### *---- "Unethical"
I paid already.
-- @Sigil, 2020-08-23

### *---- "Needs work!"
I just bought the app 2 days ago so I could link it to my employers health tracker for health and wellness incentives. It worked the first night and no it won’t open at all. I click on the app the starting page pops up and then disappears. This is why I tend to stick to free apps with good reviews, thankfully I’m only out $1.99 bit very frustrating!
-- MarianogirlsMom, 2020-08-22

### ***-- "Paid for Ads"
I paid for this App a long time ago and a while back started getting ads for the premium service... after I already paid to get rid of ads. Well, I’m annoyed with the push for premium almost every night I launch the app. I paid already, for the 4 pack I believe... why update and require more money?

Besides paying to get rid of ads, but still getting ads, the app works as expected and interestingly accurate. I know when I wake up in the middle of the night, it actually has the time recorded.
