I'd give it 5 stars but in the years I've used this app, across 3 phones, the bug that uses military time is annoying. There's no way to turn it off and, with 3 attempts via tech tickets, nobody has fixed this. I'm getting tired of being told to check my phone settings. It's not my phone. This is a bug that's been going on for at least 2 years. I'm moving on to another app.

There's no manual entry option/no way of changing a record. The only support they provide in the help section is "bring your phone with you when you leave the bed". If I am awake for an hour it says I'm sleeping deeply. To change that, I'd have to keep moving/touching my phone/talking to give it an accurate read - who wants to do that when they're desperately trying to go back to sleep. Half the functionality paid for connects to wearables, but I'm just going back to fitbit.

BEWARE! I thought this app was good at first and rated it 4 stars. The software works great. BUT I have to change it to one star because I've been noticing lately that my microphone is being accessed by this app in the background without you using the app. Mind you, I have it set to only access the mic when the app is in use, NOT in the background. That seems SUPER suspicious. Needless to say, I deleted it.
