## Review summary

Users praise Cuckoo for reliable background alerts and a simple, pleasant design, with hourly/half-hour chimes. However, several reviews note inconsistent background audio behavior, and some find the volume too soft to hear. There are also requests for more customization, such as adding personal cuckoo sounds. Overall, the app is valued for scheduling reliability and a clean interface, but it suffers from background audio inconsistencies and limited sound customization.

### Pros

- Keeps you on time with hourly/half-hour cuckoo reminders
- Clean, simple design with a pleasant, non-jarring cuckoo sound

### Cons

- Inconsistent background/sound behavior (some reviews report it plays in the background, others require the app to be active)
- Sound volume is too low or not audible enough in many situations
- Limited sound customization (difficulty adding your own cuckoo sound; options appear to be limited to presets)
