HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (3.2 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

WHAT THEY ASK FOR
  • Wish it had a repeat. 4★, Jan 18, 2019
  • The most useful thing to me would be to see a graph with a floating baseline so I could instantly see my bed times and wake-up times, length of sleep and quality of sleep in one graph. 3★, Jun 4, 2017
  • Best sounds for an alarm for those who need a gentle way of getting up in the morning. 5★, Aug 1, 2015

Horrible

App is just a Settings screen. Doesn’t do anything. Don’t buy

★★★★★Jun 21, 2023
Great

This is great

★★★★★May 10, 2023
Great rain and stream sounds

Glad I purchased

★★★★★Oct 12, 2019
Wants you to leave the screen on all night!

I can’t believe they expect you to leave your screen on all night.

★★★★★Sep 23, 2019
Jury’s still out...

I paid for this nice fancy alarm and cannot for the life of me figure out how to set it for 6:00! All it lets me do is input the number of hours I would like to sleep, but I have to actually get up to get my son on the bus.

★★★★★Aug 24, 2019
A good app, but...

This app does most everything you’d want from a standard monitoring app, it monitors and documents the nightly cycles. The graphics are cool. It needs the option to use music from your music library to wake up to. The big thing it doesn’t do, which is why it isn’t my main sleep app, is it does not work with Apple Health. Not sure why this wasn’t included, but is needed!
