It helps me to track the quality of my sleeping time. Simple but very useful. Thank you.

Does what it says. Perfect. Edit: There's a brief flash to white at the beginning, but the devs are actively trying to improve the app, as with the removal of the bright logo. So a full 5 stars from me.
β˜…β˜…β˜…β˜…β˜† Cassandra Kunkel Β· Jul 16, 2022
It's a nice app, I like the computer scheme and usability. I do not like the ads banner at the bottom, and I'm disappointed that I cannot add a "time to fall asleep" setting. It's easy to manually calculate 9 hours, 7.5 hours, etc., what I'm looking for is adding 15-30 mins for falling asleep.
β˜…β˜†β˜†β˜†β˜† Jessica Miller Β· Aug 25, 2026
Beware the ads in this app are for porn sites with a persistent ad banner on the screen that displays graphic, sexually explicit images. I've never seen anything like it from a legit app. *uninstalled*
β˜…β˜†β˜†β˜†β˜† Helen Β· Oct 23, 2025
I used to really love this app. Relied on it, but specifically loved it beyond others for its simple and intuitive design. However, recently they have started hitting me with more and more ads, which I would endure if it weren't for the fact that more often than not they have started autoplaying with loud audio, and regularly just upon opening the app! Which isn't ideal, on an app to aid sleep that one might be using at night!!! Next to, say, their sleeping partner! Very, VERY annoying.
