TrueLean™ measures how far your motorcycle actually leans - the real angle through a corner, not what a bubble level would show. In a steady corner, gravity and cornering force combine to point straight down the bike's own vertical axis, which is exactly why a plain accelerometer reads near zero mid-turn. TrueLean fuses gyroscope attitude with cornering physics, so the number on screen is the lean you're really carrying - accurate through transitions and steady-state alike. One tap zeroes your mount, and it works at any mount angle. A LIVE INSTRUMENT CLUSTER • Big, glanceable lean gauge with zone colors and max-lean markers • Speed, distance, lean, and g-force tiles, plus a ride timer • Portrait or landscape, with an OLED-friendly dark cluster • Keeps recording with the screen off or the app in the background EVERY RIDE, SAVED • Full ride history with personal bests • Route map colored by lean angle, with your deepest-lean markers • Lean and speed timelines, g-forces, and complete stats • 0–60 mph / 0–100 km/h acceleration timing YOURS TO KEEP • Export any ride as GPX (with lean/speed) or CSV from the share sheet • Hands-free start/stop via the Action Button and Siri • Built for long rides: adapts the screen, sensors, and processing to save battery without ever dropping recording fidelity PRIVATE BY DESIGN • No accounts, no ads, no analytics, no third-party SDKs • Your ride data stays on your device and is never sent to us • Nothing leaves your phone unless you choose to export and share it RIDE RESPONSIBLY TrueLean is a recreational tool for reviewing your rides - not a safety device, and its readings are estimates. Mount your phone securely, set up before you move, and never interact with the app while riding. Obey the law, ride within your limits, and save record-chasing for a closed course. Requires an iPhone with a gyroscope. Designed for a rigid handlebar/fork mount.
