You don't just watch a car anymore. You feel it. MotorPulse reads a car engine's acoustic signature in real time and translates it into precision vibrations through your iPhone. Every rev, every idle, every redline, felt through your hands. When it revs you feel it build. When it settles you feel it calm. When it hits redline your phone comes alive. It's the first app that lets you feel an engine, not just hear it. WHY EVERY ENGINE FEELS DIFFERENT Every engine has its own fingerprint. A big block V8 feels nothing like a flat-six. A muscle car idle feels nothing like an exotic at full song. MotorPulse captures that character, the fundamental frequency and the overtones unique to each car's displacement, cylinder count, exhaust, and tune. You can feel the difference between cars with your eyes closed. THE GARAGE Launch with hand-picked iconic builds, including a Ruffian Mustang and a 1973 Black Pantera. Feel them free, the moment you download. More legendary cars are on the way, dropping into the garage as the collection grows. FEEL YOUR OWN CAR Upload any car video from your phone and feel your own build come alive. Your daily driver, your project car, that exotic you filmed at a cruise night. If you have video of it, you can feel it. HOW IT WORKS MotorPulse uses Apple's Taptic Engine and real-time audio analysis to read the engine hundreds of times per second. Louder engine, stronger vibration. Higher RPM, sharper feel. It works with iPhone camera videos and downloaded clips alike. Best experienced on iPhone 13 and newer. NO SUBSCRIPTIONS You pay once and own it forever. No monthly fees, no recurring charges. Unlock uploads and the full garage with a single one-time purchase. Inspired by the moment audiences first felt an F1 car through their seats, MotorPulse brings that experience to everyday car culture. Resto mods, classics, exotics, muscle, cruise nights. The cars that deserve to be felt, not just seen. Download it. Feel it. You won't believe it's coming from your phone.
