## 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.
-- ZackInTheBx88, 2020-08-06

### *---- "Won’t open!"
I paid for this app and it won’t open.
-- vinchensena, 2020-05-27

### ***** "Getting health conscious!"
I wasn’t really into “healthy lifestyle” until there was a company program that we actually get paid staying fit. And part of that “staying fit” are ways to improve sleep and being productive and staying healthy. This was app is the accredited app for our program. At first I don’t get it but eventually the program started changing how I view “building a healthy lifestyle”.
-- MalditaWearsPrada, 2020-04-26

### *---- "Full Crap"
Inaccurate. Doesn’t even show full report.
-- GreysonNave1, 2020-03-21

### **--- "Not impressed"
The alarm doesn’t work correctly — part of the gimmick is it’ll wake you gently so as to allow you to not have sleep recoil. Tell me how playing bursts of sound is doing that because I’m just as tired when waking. Also, allow your users some functionality on things; for example, allow us to record our heart rate when we want in the event we sleep in beyond your “scheduled” reading. And give us day of the week control so we can set the alarm for the days we need it based on our schedule, not the assumption we work the same day/time each week. 
This is really a bad app for $30 a year but I had no choice since my employer is using a health tracking system that uses this to help us live better and save on insurance.
-- Eater76182, 2020-03-15

### ***-- "Features Slowly Locked Behind Pay Wall"
I got this app years ago and have greatly enjoyed its tracking features and alarm style. However, overtime more and more of the original features of the app are locked behind a paid subscription service. I paid for this app to begin with so the original features of it should be locked behind a pay wall. Soon you’ll just have to out right have a subscription to use the app even.
-- VarjoJager, 2020-03-08

### ***-- "Love this app"
I'm a very heavy sleeper and this app wakes me up gently at the best time so I don't feel groggy.

*Update on latest version.  In the iPhone X it has difficulty turning off the alarm and does not go in to take my heart rate immediately.  You actually have to go into the setting of the app then get out for the app to recognise the camera to take your heart rate. 

I loved this app but lately with the latest iOS 11 update it has not functioned as smoothly as expected.  I have the version (Sleep Time+)  that came along with my Argus purchase but I feel that it is no better then the free version. It's intigration is not as smooth as I would hope when paying for a bundled version.

*Uodate: 02/18/2020 now on iPhone 11 Pro Max lately with latest update I can no longer just open the app individually.  It shuts down but stays open in the background. 

Only allows me to use in the Argus app.  Is this because I got the bundle?   That’s sketch I’ve used this for years and it’s the only alarm I’ve ever found to wake me up without being groggy.   Also I’ve purchased and paid money for 3 apps in 11 years and this is one of them.  I am a loyal customer because I love Azumio’s layout on all of its apps except maybe Mama Calories. 

Please fix this.
-- Hnwillis, 2020-02-18

### *---- "Failed me"
I woke up about 10 minutes before the alarm so I stopped it. The app didn’t calculate my night. There is no data! I searched for info on what to do if I wake up before the alarm thinking maybe I did something wrong, but there is no help or info on this. I downloaded this app AND PAID FOR IT to use in a program for my job which has a reward system and I’m losing points because the app is unreliable. Very disappointed!
-- Lisa K E L, 2020-02-14

### *---- "Used to be good"
Several times, the alarm has reset itself and failed to go off, causing me to miss important appointments.  Time to dump this and find something better...
-- Frustrated iHome+Sleeper, 2020-01-28

### *---- "App won’t load"
I’m not sure why but my app will not load anymore. The last few times I tried to log, when I woke it was like I never set an alarm. I used to really love this app, but it’s not useable anymore
-- JumperSpecialk, 2020-01-21

### *---- "Paid content in paid App"
When I’ve purchased this App, I’ve found that this App is extremely limited and has a paid content! I’ve deleted it!
