Description

Been using Sleep Cycle: Sleep Tracker for a couple months now. It’s basically an app that tracks your sleep and tries to wake you up at the best time so you feel more rested. Pretty solid app if you’re into health and fitness stuff.

Here’s what you do: Just place your phone near your bed and it uses the microphone and accelerometer to monitor your sleep patterns. And there’s also a snore recorder, which is pretty cool. And you can set a range of relaxing sleep sounds to help you doze off easier.

Look, if you have trouble sleeping or just want to get better quality rest, you’ll probably like this. It’s not perfect – the smart alarm can be hit or miss sometimes – but overall it does the job. Worth checking out.

Editor Opinion

So here's my honest take on Sleep Cycle: Sleep Tracker. I've tested a bunch of sleep tracking apps and this one's one of the better ones. The unique sleep monitoring without needing to wear a tracker is pretty neat. And the smart alarm feature that tries to wake you up at the optimal time is a game-changer. On the downside, I've found the accuracy can be a bit spotty at times and the premium features are a bit pricey. But overall, it's a solid app that's helped me get better sleep.

I really like this app, but: 1) I often sleep in 2 phases 4-5h at night and 2-3h in the afternoon, and the app doesn't support that - second sleep...
