Editors’ Choice

When your alarm goes off in the morning, is your first reaction to throw it against the wall? The problem isn’t with you—it’s with your alarm clock. Thankfully, Sleep Cycle offers a clever solution for improving your rest. Rather than yanking you from your slumber at a specific minute, the app analyzes your sleep patterns, then picks the moment you’re sleeping lightest (within a half-hour window you define) to rouse you gently. Best of all, unlike some smart alarms, this one doesn’t need extra hardware or require your device to be resting on your bed: It tracks your sleep using just its microphone.

Picking up the other people up

Well I have found that I will be in bed awake but my husband wil be in the other room asleep. It picks him up as asleep and not me. It will only pick up when I’m as sleep and it pick him up, so the sound is picking two people up not one. That is a issue because im the insomnia person I need the date to show to my doctor when I fell a sleep and when I wake up in night to go to bathroom and get back in bed and if I fell asleep again or not and how long it takes.

Great app with some room for improvement

This is a great sleep tracking app. The sound recordings are very useful and the user experience is good. The accuracy is pretty good but could be improved. Sometimes the sleep graph doesn’t match exactly when I’m awake/asleep. Although a nice visual representation I find the sleep graph isn’t enough information - I’d like to see the amount of time in deep sleep, light sleep and REM sleep (I’ve seen some other apps have this). It’s also tricky to get accurate measurement when you sleep next to someone who doesn’t also use the app which I think is a problem common to all sleep apps, I haven’t tried the “partner feature” yet which seems good. I find the alarm system would be easier to set if you could see the amount of time you’ll be in bed for a given wake up time, instead of having to calculate this when I’m about to fall asleep.
