## What is Powertora?

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.

MEASURE
• Real power and torque curves vs RPM
• Crank-equivalent output — the coast run captures drivetrain loss automatically
• A quality score on every run, so you know how much to trust it
• Works with RaceBox, Dragy and other NMEA GPS sensors

FREE FOREVER
• Unlimited measurement
• Shareable power-curve card
• Web reports

POWERTORA PRO
• PDF dyno reports with quality breakdowns
• Merge 3–6 runs into one high-confidence curve
• Before/after comparison exports
• Multi-GPS fusion for extra accuracy
• Unlimited garage
• Road maps — curvature, grade and wind per run
• Cloud backup and recovery

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.
