Lean Angle: Motorcycle Tracker

Lean Angle turns your phone into a motorcycle lean angle meter. Mount it, tap Calibrate and ride: the gauge shows your live bank angle left and right, and Finish ride gives you a summary of the ride, every corner and your personal bests.

LIVE GAUGE
• Lean in degrees, left and right, with green, yellow and red zones at your caution and warning angles
• Max left, max right, G-force, GPS speed (km/h or mph) and ride time
• REC indicator once the zero is set; portrait or landscape; the screen stays on

TRUE LEAN (GPS)
An accelerometer alone reads low in a steady corner. True Lean adds your GPS speed and turn rate to the gyroscope so a held corner shows the real lean. A badge shows when GPS is helping.

HONEST MAX LEAN
Capped at 90°. Moments when GPS says you are stopped do not count, and when you leave the app mid-ride the swing of taking the phone off the mount is not saved.

RIDE SUMMARY AND PERSONAL BESTS
• Max lean left and right, average and top speed, distance, ride time, curves and peak G
• NEW BEST mark when max lean, distance or ride time beats your record; share the summary as an image
• Corner list with side, time, peak lean and speed for each corner, the three deepest highlighted
• Personal bests in History for rides of 1 km or more

HISTORY
• Last 50 rides with lean-over-time and lean distribution charts
• CSV export per ride; statistics report CSV across rides unlocks for 24 hours after a short ad
• Rides are saved automatically when you leave the app after 30 seconds of riding

VOICE ALERTS
Spoken caution and warning when your lean passes the angles you set, from 20° to 60°.

SETUP
Calibrate on the mount in portrait, landscape or flat. Invert left/right if needed. A first-ride card shows the steps.

GOOD TO KNOW
Readings come from the phone's motion sensors: mount the phone firmly and calibrate with the bike upright. True Lean and speed need GPS. A reference tool, not a riding aid; keep your eyes on the road.

Recent changes:
Max lean now leaves out stops and the unmount swing and is capped at 90°. Finish ride opens a summary with NEW BEST marks, History shows personal bests, a REC indicator and first-ride card guide calibration, mph works in History, and the app speaks Czech, Danish, Finnish, Hebrew and Dutch.
