## Description

PRO TREK Connected is a Bluetooth 4.0 companion app that pairs CASIO PRO TREK watches with an iPhone, enabling Mobile Link and on-screen watch controls.

Version 3.0 enables data transfer to the CASIO WATCHES app, guiding users to migrate their data and continue using CASIO WATCHES in place of this app. It supports PRT-B50 and PRT-B70 watches. iOS 14+ is recommended, and the app notes that background GPS can drain battery life; some watches may be region-restricted.

## Review summary

The PRO TREK Connected app is useful and pairs well with iPhone, with easy setup and a valued step-counter feature. However, users repeatedly report connectivity problems, limited health data integration (Apple Health), and step-count calibration issues. Many feel the app’s features are too basic beyond setup and desire enhancements like social features. The auto light feature is also intermittently unreliable. Improving reliability, data sharing, and feature depth would better meet user expectations for a connected wearable experience.

### Pros

- Seamless iPhone experience and reliable pairing
- Easy setup and pairing with the watch via the app
- Step counter is a valued feature of the watch/app
- Useful and effective app ecosystem for the Pro Trek

### Cons

- Frequent connectivity and pairing failures with iPhone (app cannot connect, needs updates)
- Lack of Apple Health / health data integration (no easy data sharing to Health apps)
- Step counter accuracy issues and calibration options missing (over-counting, weekly view offset)
- App features feel basic or limited (route tracking/waypoint recorder, lack of social features)
- Auto light/backlight feature is unreliable (turns off randomly)
