True Power

True Power turns your phone into a simple automotive performance tool with three modes:

• Acceleration (timed)

Measure timed acceleration runs between two speeds (example: 0→60 mph). The run starts automatically when the trigger detects movement and stops at the target speed.

• Dyno (power & torque test)

Estimate engine power and torque during a pull using your vehicle setup and either GPS speed (satellite mode) or OBD2 data. Designed for quick, repeatable tests.

• Live monitoring

Display live speed and power while driving (ideal for checking consistency or testing changes).

Measurement sources

GPS / Satellite: speed-based measurement (no dongle required).

OBD2 (ELM327): read speed/RPM from your adapter (Bluetooth).

Notes & history

Save your runs, review charts, and add notes to compare results over time.

Safety

Do not use the app while driving. Use on closed roads/track only and follow local laws. Mount the phone securely and ideally have a passenger operate the app.
