## Review summary

Users frequently report issues connecting the GBA-400 watch with the app, especially on certain devices such as OnePlus and Oppo, often encountering Bluetooth pairing failures. However, clearing previous pairing data sometimes resolves these issues. The app allows music control on multiple third-party apps but lacks full support for notifications and certain music players like JioSaavn. Time adjustment features in the app also do not work properly. Despite repeated connectivity problems, some users appreciate the app's music control functionality and ongoing updates supporting their older watches.

- After clearing previous pairing data, connection with the watch can be successful.
- App provides ability to control music apps without needing to download songs locally or use a separate music app like GMix.
- The app shows ongoing efforts to support older G-Shock watches and Android updates improve compatibility.
- User-friendly enough for some users to easily pair their watch and control music.

### Cons

- Frequent connectivity issues with GBA-400 watch pairing across many phone models, especially OnePlus, Poco, Huawei, and Oppo devices.
- Bluetooth connection often fails or turns off during pairing process despite granting permissions and battery optimization.
- Limited or no support for notification alerts (e.g., call or message notifications) through the app.
- Some features like time adjustment on the watch via the app do not work or are difficult to use.
- App does not support certain music apps like JioSaavn, limiting music control options.
