Measure acceleration times such as 0–60 mph, 60–120 mph and 1/4 mile directly with your iPhone — accurately and without extra hardware. The app is designed so it doesn’t need to be operated while driving; you just set everything up beforehand while stationary. Measurements then start automatically — when the target speed is reached or when a start is detected. You can save results locally on your iPhone and, if needed, export them or transfer them to other devices. Preset timers: 60 ft, 1/8 mile, 1/4 mile, 1/2 mile, 1 mile, 0 – 60 mph, 0 – 120 mph, 50 – 75 mph, 60 – 120 mph, 0 – 100 km/h, 0 – 200 km/h, 80 – 120 km/h, 100 – 200 km/h. All timers are, of course, fully adjustable. The free version measures up to two times per run. How to use the app: Check the timer settings on the start screen. If everything looks good, place your iPhone in the car where it has good GPS reception and is held securely, then start the acceleration test. You can adjust the timer configuration in the Settings screen (just tap the relevant timer). Then return to the race screen and follow the previous instruction. Optional PRO version (in-app purchase): 1. Up to four timers in parallel (instead of two) 2. Precise determination of elevation differences 3. Simulation of a Sportsman start and reaction-time measurement 4. No ad banners

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 call
