## Sleep Time Reviews in United States

### ***** "Perfect and free"
I needed an app to track my sleep for our insurance plan to pay us. I tried app after app for a week and all wanted a subscription. Finally I found this one and it worked perfectly!
-- Scabshouse, 2024-12-23

### *---- "Ads won’t close"
Used this app for years for my alarm. The ads won’t click away now to even use it. Deleting and getting something else
-- Toribethhhhhh, 2024-09-04

### *---- "Ads that can’t be clicked away"
This app has now started to have ads that can not be clicked away, and they don’t time out. Makes the app completely useless.
-- Fire_mike, 2024-08-28

### ***** "Best free sleep app"
This is the only free sleep app I’ve found that actually works! I have considered upgrading, but I can’t find anything that explains the premium features. I wish it would give some examples of sleep reports or sleep programs, but that’s literally my only complaint, so, highly recommend.
-- Krystenwithay, 2024-07-11

### *---- "loud ads, ads in foreign languages, bad reviews"
I've had the app for years and the devs have experimented with ugly ways for them to make a buck off of you - playing loud pop up ads as you're setting your alarm  - I even have gotten ads in foreign languages where the close button is (I assume) the word "close" in that language... not to mention how they hound you to set up an account (more data collection).
I've also had my share of mid-night crashes that cause me to miss waking up on time. 
very unsavory and antagonistic view of their user base - avoid this app.
-- snackfudge_, 2024-04-24

### *---- "Alarm no longer makes noise"
Have waken up late for work twice now due to the alarm not making any noise. Will be switching apps immediately
-- No8383838, 2023-12-21

### ***** "Waves"
Love the waves on the beach sound, so peaceful.
-- bosn Dan, 2023-09-28

### *---- "Obnoxious promotional ad noises"
I cannot believe yall read all these comments and decided “oh we’ll put a blaringly loud noisy ad to promote our premium app and the only way to get rid of it is to go and ignore the ad”. The weird freaking alieny music that gets louder by the second unless you X out of the ad is absolutely insane. I’m honestly shocked that you guys really did this. Absolutely horrible. Would not recommend.
-- MissN525, 2023-09-24

### ***** "Great app"
I’ve been using this app for about 4 years now and I love it. It really makes a difference and helps me get insights on my sleeping habits
-- LBudze, 2023-09-05

### ***** "Since 2014 i use it"
Amazing
-- Deel2012, 2023-09-03

### *---- "Loud Ads"
Stop having loud ads!!!
-- kal414, 2023-08-31

### *---- "Terrible noisy commercials"
How is it OK to play a noisy commercial at midnight when I am setting my sleep timer on next to my sleeping spouse. Sleep time you have to do better! It us not OK to blast a commercial on full volume at all. I understand the need for commercials, but please turn off the sound!
-- gioneva234, 2023-08-22

### ***** "Best app"
Been using this app for almost 10 years and it is very reliable
-- mortimois, 2023-08-15

### *---- "MAY DAMAGE YOUR EARS"
Allow users to disable volume change

I don't use an alarm, I just use the vibrate and the analysis. Don't touch my volume. Edit: Huh, looks like the Alarm Volume maxes out regardless of its setting. This is DANGEROUS. Do not max my volume ever, I might have buds in. My ears still hurt :(
-- bob_______, 2022-12-16

### ****- "I have been using this app since April 2014"
When I first started using this app, it was amazing. It actually recorded when I would sleep and listen to the deep/light sleep periods. 

Something happened one day when it updated and it never worked the same. If I remember correctly, it was related to the iOS restrictions to curb apps monitoring you all the time. So I believe they were forced to change the algorithm to checking in periodically rather than constantly. 

This led to a less desirable tracking. While although that was great at the time, what I love is the alarm. 

You set your window, mine is 30 minutes. And if I set my alarm at 7, it could wake me up anywhere between 630 and 730. It tries to listen more during that time and if I stir, it’ll play the gradual melody to wake me up. 

What gets people is the snooze. Shake the thing and it’ll snooze. There’s another parameter you can set to lower the snooze time and the amount of times you can snooze. If you say 10 mins, but say you can snooze 3 times, that’s 30 mins. My alarm would then max wake me up at 8 by my example. 

So on average if I want to wake up around 7, I would set my alarm at around 6:10. 

If you want a “hard wake up” like a normal alarm clock. This app is not for you.
-- Pizza Gut, 2022-09-28

### ****- "Soundscape buggy?"
I’ve used this for years- love the simple dial interface- always works for me- love the ability to flip my phone for snooze- fantastic product. Recently I’m unable to get iTunes to launch to pick my soundscape- maybe a bug? iOS 15.6.1
-- njm8591, 2022-08-31

### *---- "Alarm doesn’t go off"
Was late because the alarm never went off. And they make you sign up for an account. Useless app. Don’t bother downloading.
-- LauraBa1990, 2022-08-16

### ***** "Interface not intuitive"
The red x on the ads does not remove the ads, it launches the ads!  Please remove the red x if the ad is not allowed to be removed.  That is just mean!  

The screens are also very unintuitive, I would never buy premium with such a bad design.
-- Me and the dogs, 2022-07-21

### **--- "Frustrated"
I tried it free and decided to buy it. But it won’t allow me to add my name to the account, therefore the app won’t generate reports!! I’ve contacted the company and no response. Thinking about canceling soon if no response or help.
-- Justinbieber01, 2021-12-13

### ***-- "Full volume autoplay ads- that’s what you want at bedtime!"
You used to be able to bypass the ads by disconnecting from the internet— not anymore. 

The free form of this app is unusable. It’s not a free app with purchase unless the grub hub commercial jingle really gets you sleepy— it’s just a paid app.
-- Shiplizard, 2021-11-16
