(5★) I love this app!
This app not only woke me up but it made sure that I was being woken up at the proper times that would make it so I wouldn't be

(2★) Best app. If it works
Had this app for about a year now even bought the full version which I don't do unless I really like an app. Always worked fine

(3★) The free version works better!
The snooze button on the paid version does not work half of the times. Loved the free version and updated the app just to get rid
of adds. Sorry to have done that now. Please fix.

I use the program only occasionally. I would use it more often if it were able to connect to one of the activity centers like the

(5★) Does the job
Good variety of sounds. Great baseline info
(5★) Work great
Everything about this app is great: the graphs, the user interface, no ads. The only downside is that it doesn't record the sounds
you make during the night.
Jun 26
(4★) Naps?
I can't get it to keep track of naps during the day. It wakes me up at the desired time but doesn't show what I slept. It may
sound weird but I want to track naps too.
(4★) Getting a hold of habits and sleeping
This program is helping me gather my sleep habits. So far I can see a trend.

I find this makes waking up less of a battle. Even if only by suggestion, I choose to believe that waking up naturally is actually

(3★) Good app
I like the application data that is local but don't waste your money on the "more" detailed report subscription. I found it
lacking in anything new compared with the local data. I have requested a

(4★) Great sleep app bad do it all app
Great sleep app has good sensitivity vs other apps it can pick up movement on my memory foam bed. Good design probably best of its
kind. Only downside is a lot of features require a 5 monthly fee, so
Jun 15
(4★) Great!
I love this alarm. I do notice that sometimes if I hit snooze too many times it doesn't register that nights sleep into the data
chart. That would probably be my only grievance.
(2★) Big Fail Since the Update
Edit: Updated to iPhone 6 and works. Very disappointed it doesn't integrate with Phillips HueBulbs. I've religiously used the app
to sleep and wake up on my iPhone 5s. Ever since the last app and iPho

I love this alarm. Knowing how well I sleep each night gives me insight into lifestyle changes I need to make before bed.
(4★) Forced review
It's a wonderful alarm. It keeps extensive records of your sleep patterns and times and compiles data. You can check heart rate
etc. however, buying all the extras is hardly optional and writing this

(4★) Better than OK
I've enjoyed this app for yeasts now, and it definitely works for me. I wish there were more nature sounds to choose from though.
Jun 06
(5★) The last alarm I'll ever buy.
It's amazing to wake up so easily and refreshed. This app also shows when I hit my deep sleep. It's been the beginning of an
incredible movement toward better overall health and self awareness just by

This is the only alarm my wife likes cause it wakes me up slowly without disturbing her. And it goes off when I'm most awake so I
actually wake up.

Love the app except. I have a slight complaint perhaps you can advise. I am an insomniac. I've been so for 13 years. I usually go
to sleep about eight in the morning and wake up about noon. My average

This is one of my favorite apps by far! Thank you!

After using it for two nights, the alarm began its almost imperceptible chime on the third night at just the right time. I woke up
alert and refreshed 20 minutes before my usual wake time. Excellent a

Its kind of a novelty but the alarm works well. It's effective and isn't a super annoying buzz.

(5★) Great way to track sleep over time
WHAT I LIKE:I use this app every night to get to sleep. I play one of the included soundscapes and drift off. I love that in the
morning I can look at the graph of what stages of sleep I was in (inclu

App keeps crashing in the middle of the night. My alarm hasn't gone off in days because of it.

(5★) Dependable alarm
This is my default alarm device for daily wake ups. Easy to set and change. The sleep graphs are most interesting.
(5★) Wonderfully helpful.
I use it every night, and it's not let me down yet. A must have.
(5★) Fantastical Alarm Clock
Best alarm clock ever. I wish I could flip the graph as its upside down from every calendar I've ever used but its the best alarm
clock I've used. So subtle sound to start and gets louder 'til you are

Digital clock added! Changed my rating back to 5 stars. I've used this app for 2 years with no issues until this latest update. As
other reviewers have mentioned, the numbers on the clock have been re

(5★) Interesting Data
Using this app has helped me see truly how little sleep I get and helped me to see I need to get to bed earlier cause once 5 or 6
AM comes around I no longer go into deep sleep.
(4★) Worth it!
I have been really satisfied with everything this app can do. If you are a data junkie you'll really like the data interface.
Although i don't have any issues falling asleep at night, this app has hel

Not sure how this app compensates for outside motion, like spouses and pets flailing at all hours of the night. How can I be sure
of accuracy?Also. Need this to be useable on the Watch, stat! Please :
(5★) Use it every night
One of the few non-core apps I use regularly. Great alarm, very reliable at waking you - I have to get up at odd hours for work
so this is important. Helps keep track of the naps and short stints

It's great! I have no regrets. My pulse always seems to be over 80 bps.
Apr 18
(4★) Very nicely formatted app!
As far as the whole as an app it is very good. I like that it guestimates my sleep cycle in what looks fairly accurate! I do wish
the had more ambient tones and white noise. To give more of a variety.

(4★) Solid sleep app when paired with Argus
I originally gave Sleep Time a thorough and very positive review- since then I have used it for over a year. I also used Sleep

This alarm clock help a deep sleeper like me wake up every morning. You wake up slowly and nicely. This alarm clock is like that
teacher that shakes you gently when sleeping in their class unlike that

Great over alarm but it advertises a sound scape that I really loved from the free version but I've searched everywhere and
there's no way to keep the sound running on the clock page.

This is by far the best alarm app I've used; and I have tried ALL OF THEM. BUT. Having experience with other apps, it's always

Simply not satisfied, tried the free app and then purchased hoping for more functions. Could not set alarm or needs to set alarm
each day, only analog clock, cannot resize or pivot

This alarm is fantastic. Pandora, or even my default alarm, usually didn't wake me up when I wanted it to, which was most annoying
because I live on a very tight schedule, and sleeping in is usually n

(5★) Great way to improve your sleep
I have only been using this for a week now but I have been able to determine my sleep patterns and continue to improve the amount
of time I'm in a deep sleep each night.

Seeing my sleep stats really helps me see when I am getting too little sleep for too many days in a row. I also love that the

(4★) It's best app I've ever downloaded!

This used to be a great app, but In the latest update, I was frequently woken up at the WRONG time. Fix it.

(2★) Deletes data during updates
Great premise for an app, but annoying. I updated the app once and it deleted all of my data. It constantly nags you to upload
your data under the guise of protecting it from loss (which turns out to

I always thought I had sleep problems, this app has helped me to relax and okay with the times I wake up. I'm getting a much

Helpful app. Glitchy periodic shutdowns frustrating. Data good. Would like to have a simple method to note anomalies in activity
that may affect sleep pattern, visible in the Weekly View
(5★) Great, informative, and easy to use
I use this every night and it has been the best alarm for 2 years. Your choice of alarm sound helps a lot, too. I always recommend
it to friends.
(5★) Can't go back to a regular alarm clock
I don't know how it does it but I always feel amazing after waking up with this app. Took a little getting used to waking up
before your alarm time, but then you realize you're better off without it.
