Diagnosing a rough engine? Don't guess. Don't dismantle. Don't pay for hours of workshop time. Crankotix is the world's first iPhone-based relative compression tester. Using nothing but your phone's built-in magnetometer, it reveals the health of any 3 or 4 cylinder engine - diesel or petrol- in less than 30 seconds. HOW IT WORKS 1. Remove the fuel pump fuse, disconnect camshaft sensors or disconnect the ignition system... (according to the engine technology) 2. Place your iPhone near the negative battery terminal 3. Crank the engine for 5 seconds (Follow the audio instructions) 4. Get instant relative compression results That's it. No probes. No Bluetooth dongles. No mechanical tools. Just your iPhone. WHY IT WORKS When the starter motor cranks your engine, every compression cycle creates a current spike. These current spikes generate magnetic field variations which your iPhone's magnetometer captures. Crankotix analyzes these signals and tells if the relative compressions are well balanced. WHO IT'S FOR * Used car buyers who want peace of mind before signing the check * DIY mechanics tired of mechanical compression testers and oily workshops * Independent garages looking for a fast pre-diagnostic tool * Anyone who values their engine KEY FEATURES - 10-second test, instant
