User Reviews

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).

Recent reviews

If I could give 0 stars I would. It’s unbelievable to me that HP Tuners forces me to use TDN to tune some car combos and it just doesn’t work more than half the time. On top of that they have the slowest support system ever, I opened a ticket 14 days ago and have gotten 2 replies, both asking for info I provided when I originally opened the ticket. I never write reviews for anything but it’s honestly that bad.
