You'll use the TDN (Tune Delivery Network) App to manage tuning:
Flash between stock and custom tunes
Send and receive tune files
Record and share data logs
Read and clear DTCs (Diagnostic Trouble Codes)
... all from your mobile device.
Here's a quick video on how it works: HP Tuners - YouTube Short - How to tune with the TDN App.
