Send and receive data from a BLE device to your MQTT broker with this app. Perfect for BLE enabled IOT devices. Example Arduino sketch available on the support website.

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.
