## Description

The Tune Delivery Network app enables your TDN tuner to send you their tunes for your vehicle. An HP Tuners RTD+, MPVI3, MPVI2+, or other TDN-compatible delivery device is required.

Please note that this app is designed for users who have a relationship with a tuner that is part of the TDN system, and is not intended as a solution for self-tuners or non-TDN tuners.

## Review summary

Users praise the app for fast, integrated tuning tasks (flashing tunes, data logging, DTC read/clear) and for helping with customer workflows and scheduling. However, the majority of reviews cite reliability issues: frequent crashes or inability to open, persistent Bluetooth/MPVI sync problems, login failures, tune transfer/file errors, and compatibility problems after updates. Overall, the app shows strong functionality in theory but is plagued by stability and reliability issues in practice.

### Pros

- Fast and easy flashing of tunes, data logging, and reading/clearing DTCs.
- Helps streamline tuning workflows for customers, including scheduling.
- Multi-function app enabling tune downloads and on-device tune operations.

### Cons

- Frequent crashes and instability; app often won’t open or crashes during use.
- Ongoing sync/connection issues with MPVI hardware and Bluetooth; frequent resyncs.
- Login problems: app logs out or won't log in.
- Tune transfer/download errors and file not-found issues.
- Update/firmware compatibility problems with iOS and devices (QA issues).
