iPhone
Turn your phone and a GPS sensor into a dyno. Measure real crank power and torque from a single pull — no rollers, no shop. Now on iPhone.
Powertora turns your iPhone and a Bluetooth GPS sensor into a rolling-road dyno. Do one full-throttle pull followed by a coast-down on a quiet road, and Powertora calculates your car's real power and torque curves — crank-equivalent, in metric PS — from how it accelerates and how it slows.
No rollers. No dyno shop. Just your car, a GPS sensor, and a stretch of road.

HOW IT WORKS
Pick your car, enter its weight, and drive: one pull to the limiter, then coast back down on the same road. Powertora does the physics. Measuring is free — upgrade to Pro for the full tuning workflow.
Powertora Pro is an auto-renewable subscription (monthly or yearly) or a one-time lifetime purchase. Payment is charged to your Apple Account; a subscription auto-renews unless turned off at least 24 hours before the period ends, managed in your Apple Account settings.
