## Review summary

Users praise Cozy Timer for its simple design and reliable sleep timer, with years of use by many. However, feedback centers on update-induced problems: intrusive ads, playback controls that stop working, broken fade-out, and removal of handy on-screen features; plus purchase/account issues hindering premium upgrades. When it works, the app is highly valued, but reliability and user experience suffer due to ads and regressions.

- Reliable timer that works and is easy to configure.
- Handy timer with useful features.
- Longstanding, trusted by users over years.
- Positive sentiment when the app functions correctly.

### Cons

- Intrusive, full-screen ads and frequent ad interruptions.
- Updates frequently break playback controls (pause/stop) and can affect volume/fade-out.
- Removal or hiding of convenient features on the main screen (end-time clock option).
- Premium purchase and account issues prevent upgrading.
