Great

Fantastic app. Recommended it to a professor after just two days.

Been using it for nearly a decade and a half since. Ensures I feel well-rested when I wake up. The few times a year I use a regular alarm I can feel the difference in the morning.

Every couple years update this review. I really hope they keep supporting this amazing app.

I bought it but they won’t let me use it

I installed the app on a new phone, and I can’t get get past the trial paywall, there’s a link to restore purchases but doesn’t work so can’t use it

Can’t restore purchases on Duo

The app looks great on Duo, but I can’t get past the setup screen because I can’t restore my purchase. I’ve been a paid Sleep Cycle customer since the very beginning, so I’m disappointed I can’t continue giving you guys money.

5* but would love some more stories

I’ve been using sleep cycle for years. It’s been my go to for regular alarms, but also amazing on nights where i’ve not been able to get to sleep. The stories always send me off, I would just love some new ones!

Trial Period data was to darkened to read

There appeared to be a useful series of data, but the data was too darkened to be able to read. In addition, there was no recording of snoring. With those serious issues, I am not willing to purchase a subscription.
