User Reviews

Sleep Time+ offers solid sleep tracking and a gentle wake-up experience, and many users value its long-standing data history. However, users repeatedly report crashes, data export/Health sync problems, a heavy subscription model with opaque pricing, unreliable alarms, and slow or absent updates for newer iOS versions. The app’s core idea remains strong, but reliability and monetization concerns dominate the feedback.

Pros

Tracks your actual sleep duration and shows how much sleep you’re getting.
Wakes you gently at an optimal time, reducing grogginess.
Long-standing app with years of usage and a large data history.
Reported to improve sleep compared with other apps.

Cons

Frequent crashes and stability problems; the app often won’t open or crashes on launch.
Sleep data export/Health app sync doesn’t work; data isn’t transferable.
Subscription model and pricing are heavy-handed and often push premium features with ads.
Alarm reliability issues; alarms may trigger early, fail to trigger, or reset.
Not updated regularly and shows compatibility issues with newer iOS versions.

Helps me to know how much sleep I’m actually getting. I do love the soundscapes to help me fall asleep. Makes it easier.

I’ve been using this app since 2012 so I have amassed lots of data over the years. Regrettably, Azumio pays very little attention to this app and it hasn’t been updated in a while. There is no way to get the sleep data out of the app that I’ve found, even with the Premium version. Supposedly it syncs with the iOS health app but the Health app finds no Sleep Time data to sync so 🤷‍♂️. Also, it’s extremely buggy. Crashes a lot when trying to update tags, etc. I would move to a different sleep tracking app if I could get the data out of this one.
