## Review summary

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.
