Customer Reviews

One of the most useful apps I've come across

The true value of this app is not described very well. A person can maximize their sleeping enjoyment based on what they do in their day-to-day activities.

I think a person is best rested if they maximize their deep sleeping capabilities. This app has been allowing me to do that. The app can be pretty fun too with the sleep talking capability. I don't sleep talk myself but my cats are always sent setting it off in the middle of the night. The app can also track how many times you have to get up and use the bathroom. This allows you to fine-tune your diet so you sleep more effectively throughout the night. This is a great and very useful app.

Lots of detailed information about your sleep

I really like the sleep cycle alarm feature that attempts to wake you up at your lightest stage of sleep; it seems to be working for the most part. There are plenty of settings for customizing the alarm to your liking. The "spare alarm" is also a lifesaver.

What's really nice is seeing your sleeping patterns visualized, with various statistics presented to you after waking up. Apple Health integration is also neat.

A noticeable flaw so far is that the battery meter on the status bar still shows through the night background, but the black text is hidden, creating a UI discrepancy.

Use it on daily basis

I did notice the difference between using this and a hard stop alarm. The latter one just simply a cold bucket to wake you up versus this app is kind of like gently tapping you. Love the fade in music alarm feature. I almost look at the analysis graph every morning to see how my sleep was. I hope they all were close to accurate. I wish there's a feature like an app I used before: according to the time the user sets the alarm, it suggests the wake up hours. I don't know if it's based on some sort of science but back in the days when I used it, I woke up with ease.
