Lean Angle is a motorcycle lean angle meter and ride tracker: mount your phone, tap Calibrate, ride, and see your live bank angle, then tap Finish ride for a summary of every corner and your personal bests. ▶ Live lean gauge • Left and right lean in degrees on a big gauge that turns green, yellow and red at your caution and warning angles • Max left, max right and G-force tiles, plus GPS speed (km/h or mph) and ride time • A REC indicator shows when the zero is set and the ride is recording • Portrait or landscape, and the screen stays on while the gauge is open ▶ True Lean with GPS In a steady corner an accelerometer alone reads too little, because gravity and cornering force add up along the bike. True Lean combines the gyroscope with your GPS speed and turn rate so a held corner shows the lean you are really carrying. A badge tells you when GPS is helping and when it is still waiting for a fix. ▶ Max lean you can trust The lean is 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 left out of the saved ride. Your max lean is a number from the road, not from your pocket. ▶ Ride summary and personal bests Tap Finish ride and the summary shows max lean left and right, average and top speed, distance, ride time, number of curves and peak G. Max lean, distance and ride time tiles that beat your personal best get a NEW BEST mark, and the card can be shared as an image. • Corner list: every corner with its side, time, peak lean and speed, the three deepest highlighted • Personal bests in History: deepest left and right lean, longest ride, total distance (rides of 1 km or more) ▶ History • Your last 50 rides, each with a lean-over-time graph and a lean distribution chart • Export any ride as CSV; a statistics report CSV across all 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 Hear a spoken caution and warning when your lean passes the angles you set (20° to 60°), so you never have to look down at the phone. ▶ Set up once • Calibrate on the mount: portrait, landscape or flat • Invert left/right if your mount reads the wrong way • A first-ride card walks you through mount, Calibrate, ride and Finish ride ▶ Good to know Readings come from the phone's motion sensors, so mount the phone firmly and calibrate it with the bike upright. True Lean and speed need GPS. This is a reference tool for curious riders, not a riding aid: keep your eyes on the road and ride within the law. For sport and touring riders, track-day riders and anyone who wants to know how far they really lean.

Verdict
The clearest difference is price: Lean Angle at Free against Alert Position's $1.99. Lean Angle also leads on update cadence (every 10 days vs every 11 months). Alert Position's advantage is rating (5.0 vs 3.0) and ads (none vs shown). On ratings volume, in-app purchases and iOS requirement there is nothing between them.
