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

I have been really satisfied with everything this app can do. If you are a data junkie you'll really like the data interface.

(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.

(3★) Seems ok, but.
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

(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

(5★) Just beautiful
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

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

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.

(5★) Needs Customization
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

(2★) Don't buy the report part!
The app is not bad - some mornings it won't go the statistics page to let me do the heart rate. I bought the insight report part

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★) Love this app!
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 app is incredible! It's not an alarm clock it's a sleep management system! Wakes you up slowly and you feel refreshed! It

(2★) Y u no fix bugs?
This used to be a great app, but In the latest update, I was frequently woken up at the WRONG time. Fix it.
Mar 29
(5★) Happy Customer
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
better quality of sleep than I thought. Very re assuring!
(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

For those of you who don't sleep very well – and sleeping is not a priority, but more of a necessity – this app helps you see
how much good sleep you're getting and that will allow you to make adj
(4★) I need more sleep
It's a good app. Does what it says - it's sobering to see what your sleep is like in print. Nice graphs. Pretty colors.

Mar 26
(4★) My primary alarm clock
Works well, gives a rough idea of the quality of the night's sleep. Easy to use. It is a battery hog, though.
Mar 25
(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.
(4★) DiGz
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★) 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.
Mar 23

This app works great. It really does a good job at waking u up at the ideal period in your sleep so u don't feel groggy. This is
the only app that I have paid for and I am happy I did. The snooze als

I think this is the best sleeping app I've ever used. I've only been using it for a week but it's so nice. It wakes me up

Graphically even more attractive, but a few bugs crept in. Nothing major. Still a great and gentle alarm clock. HealthKit

(5★) Not a morning person
I'm an NOT a morning person. I wake up everyday NEEDING to go back to sleep. Since I'd gotten this app, I've found it a lot easier
to wake up in the morning. I'm not as immediately tired no matter how

(3★) You're Not Apple
Everyone wants to be Apple. So they design these "clean" pieces - like clocks with no numbers and graphics with skinny lines that
are difficult for some people to see without their glasses. Why? The L
(4★) Great Birdsong alarm, too
This app does everything you could want except there is no screen rotate to 'landscape' orientation, hence 'only' four stars. It
has a great connection to my wrist monitor (LifeTrak), it is colourful

(4★) Almost awesome
I've never been awakened so gently, it's amazing! I only wish they'd fix the bugs with entering birthday and running sleep
Feb 28
(4★) Nifty App
The app itself is great, works like a charm. The email sign in system is hopeless though. I would love to see more options for
sleep sounds.

(5★) Excellent app
The alarm is fantastic! The way to start, the snooze are superb. I wonder if the sleep analysis is serious and how it works.
Anyway, after a long time using it, I still check the analysis every mornin

(5★) The best
The best alarm I've ever used. I love this alarm. It wakes me up slowly and there's no "jolt" to wake up. I don't understand the
complaints some users have. They may need to update their phones becaus
(2★) Daily user but inaccurate
I have a memory foam bed and this app doesnt account for that so I wake up when I shouldnt. Also the app thinks Im sleeping even
though Im wide awake and still moving. I only use it to fall asleep to

(3★) Waste too much battery
The app mainly uses battery in my mobile.

(4★) My alarm clock
This app was well thought out. I like the gradual increase in volume the alarm has, that the volume is independent of phone
settings, that you can pick songs from your phone to be played as the alarm

(5★) Love the iHealth Integration
Very nice app that helps analyze sleep patterns, with an alarm.
(2★) Good but.
I can fool it. It tracks by movement not if your actually sleeping. Also there have been times it wakes me in deep sleep even
though there is still time before alarm set time. There also have been a c

I've been using this app as an alarm/sleep tracker for a little over a year and have always liked it. I have ADHD and have always

(5★) Sleep app
A superb app. Easy to use & non-obtrusive. Gives very useful data. Ties in with the health app on my iPhone 6 seamlessly.

(5★) Awesome app
Love how this app can identify the best time to wake you up within a given window!
(4★) Uninstall the update
The Heart rate was much more convenient before the update of sleep time. Heart Rate app results do not transfer to sleep time. It
is Stall an outstanding app.

Really like the gentle alarm on this app.

(2★) This WAS a great app, not so much now
This was a great app that I happily paid 3 for (an extreme rarity for me) several months back. I paid to have full access to the
