Sometimes it's accurate but I'm really happy I was running other tracking apps - it told me I was awake half the night and that's not even close. More accurate apps said 7hrs 13min which is pretty close, possibly exact - after all the were 2 apps that said it. This app told me I got something like 2hrs 20min. If you use this, make sure you have at least one other app running. Also every time I look for history or averages this app tells me I haven't used it yet! I recommend finding a different app if you want to find out how long you REALLY slept or to look back or to see any statistics or check out your history. My sleep IS usually a couple hrs, 3 if I'm lucky, so this app couldn't be too far off before but comparing over 7 hours actual to approx. 2hrs, it was obvious the app is useless. I don't usually use the sign but had I it would've thought I was awake so I don't think even the alarm would've went off, let alone at the "best" place in my sleep cycles. I think it's time to delete but the apps have similar or the same name so I'll keep this to make sure I don't download it again or EVER use it again. After all, according to it I HAVEN'T used it at all!
