HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (421 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. 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.

Lost data, sync, backup8%

28 of the 1 and 2 star reviews.

★★★★★ Helps to improve your sleeping to brain quality sleep You wake up feel more rested
★★★★★ I wasn't interested in getting to sleep or waking, only the quality & amount of sleep.
★★★★★ I couldn't figure out why but for a couple weeks it kept saying my sleep quality was less than 20% and that I didn't sleep all night racking up sleep debt as high as 40 hours in one week.

Stay away

They say they have a free version, but you have to give them your credit card for a “free trial that starts charging you. That is a scam.

★★★★★Jul 28, 2026
Problems

Been having a lot of problems with the app lately, not quite sure what the heck is going on. Can’t seem to get the tracker to open anymore.

★★★★★Jul 10, 2026
Decent, But Nothing Special

The app does the basics well and is easy enough to use, but it didn't really stand out to me. The interface is okay, and the sleep tracking seems decent, but I was expecting a few more useful features and a smoother overall experience. It's not a bad app, just fairly average compared to other sleep trackers.

★★★★★Jun 7, 2026
Great, when it works

I’ve now used this app for a few months, usually stops working for about 3 days. Then suddenly it works again. I reboot my phone, I clear the ram, I’m a geek so I do all the necessary things. But yet, it still fails 3 days out of a 4 day work week. Considering it’s an app that I have PAID for, it is quite annoying that it only works part time, even after updating it, uninstalling it, reinstalling it. I have the latest IOS device and software, so I don’t know what else to do besides throw my phone at the wall now

★★★★★May 12, 2026
No way to swap it for day sleepers

It’s only set up for people who sleep during the nighttime there’s no night shift settings but could be cool

★★★★★Apr 14, 2026
Unfortunately bad now

I’ve had this app for many years and even when I switched to other apps I’d come back to this one. The freezing now is unbearable I shouldn’t have to keep a backup app in case this one doesn’t load. Today, the alarm just didn’t go off; it’s happened before but I really needed to be up early to have my day set up properly, so this was my last straw
