## Description

OnTrack is a CarPlay-enabled OBD2 scanner that connects to your car's OBD interface to deliver real-time performance data on the track. Monitor RPM, coolant temperature, oil pressure, and more with a clean, racing-focused display.

New feature: custom temperature alerts with instant notifications, so you can define limits for coolant or oil temperature and stay ahead of issues. The app integrates with CarPlay for on-dash monitoring and requires a Bluetooth 4.0 OBD adapter.

## Review summary

OnTrack shows promise with CarPlay integration and real-time data display, and some users report automatic startup connections and responsive support. However, a pattern of connectivity problems with multiple adapters, iOS stability issues, and pricing/feature limitations dominates the feedback. Users desire more gauges, more PID support, and clearer pricing. Overall, CarPlay functionality is a strength, but reliability and feature parity need work.

### Pros

- CarPlay compatibility allows viewing vehicle data on the CarPlay screen.
- Real-time data display with quick updates.
- Automatic connection on app launch reported by some users.
- Positive developer responsiveness to feedback.
- Works with at least some OBD adapters and shows readings when connected.

### Cons

- Frequent connection failures or unreliable pairing with several OBD adapters (OBDLink CX/MX+, BlueDriver, Vgate iCar Pro BLE, etc.).
- Stability issues on newer iOS versions (iOS 18) causing crashes when connected.
- Pricing and feature limitations (subscription around $4/month; unpaid version limited to two sensors; limited features).
- Limited feature set (few PIDs, no gauges, no light mode, limited UI options).
- Support response can be slow or inconsistent (variable user experiences).
