Accel Timer vs Launchly

Accel Timer is a GPS performance timing app built for drivers, riders and anyone who wants clear, repeatable run data. Measure acceleration and distance runs with live speed, G-force telemetry, countdown starts and GPS-based timing. Choose between automatic movement detection, custom speed ranges or countdown starts, then review your best results in a clean history view. Use the live map to follow your route, switch between map styles, and record your runs with the optional camera mode. Share polished summary cards showing your time, distance, speed and altitude difference. Perfect for 0–100 km/h, 0–60 mph, 400 m, 1/4 mile, custom speed ranges, cycling sprints and running distance tests. Key features: • GPS speedometer with analog gauge styles • Real-time G-force telemetry • 0–100 km/h, 0–60 mph and custom speed timing • Distance runs from 100 m to 5 km • Countdown, movement or speed-threshold start methods • Live Mapbox route view with map, satellite and hybrid styles • Optional camera preview and run recording mode • Local run history with best results • Clean share cards for posting your runs • Flexible settings for units, timing, sounds, layout and video behavior Accel Timer helps you test, compare and share performance runs without clutter.

Find out what your car really does. Launchly is a GPS acceleration timer for your car. It measures 0-60 mph, 0-100 km/h and the quarter mile from a standing start, to within about a tenth of a second. Pick a target, floor it, and the time is on screen before you have come to a stop. MEASURE A SPEED OR A DISTANCE Run to a speed: 0-50, 0-100, 0-150 and 0-200 km/h, or 0-30, 0-60, 0-90 and 0-120 mph if your phone is set to imperial. 0-60 mph is a finish line of its own rather than a converted 0-100, so your acceleration time is comparable with what the motoring press publishes. Or run a distance: 100, 200 and 400 m, or the 1/8 and the 1/4 mile. Every distance run reports the elapsed time and the trap speed over the line, the two numbers a drag strip time slip gives you. Whichever you pick, the run records its splits at every line it crossed on the way, in both unit systems. Switch between km/h and mph and your history and your records come with you. ACCURATE ON AN ORDINARY PHONE Most phones deliver GPS just once per second. Across a four second launch that is five data points, nowhere near enough on its own. Launchly reads the accelerometer at 100 times a second and fuses both signals live, then refits the whole curve against every GPS reading once the run is over. No external performance box to buy or charge. The launch is detected by the accelerometer, so your timing does not have to be perfect, and the start and finish moments are interpolated between samples rather than rounded to the nearest reading. SEE WHAT THE CAR DID Every run is kept with its full speed curve, its G-force trace and peak G, its split times and the conditions you set it in. Not just the number it ended on. There is a live speedometer while you drive and a gauge you can switch to a face you like. Export the raw GPS log and the fused speed curve as JSON if you want to dig further, or share a rendered card of your run. YOUR GARAGE Add every car, bike or van you drive, each with a photo and a licence plate. A Dutch plate pulls make, model, year, engine and colour from the open RDW registry automatically. Every run is filed against the vehicle that set it, and a personal best is kept per car per target. YOUR FRIENDS Add friends by invite code and every run you choose to share lands on one leaderboard, ranked per person and per car, with the top three on a podium. Metric and imperial runs sit on the same board and are compared on the same finish line, so a friend in Rotterdam and a friend in Austin are actually racing each other. Nothing is shared until you share it, and nothing is public. Only friends you have accepted can see your times. ON YOUR PHONE, IN YOUR LANGUAGE English, Dutch, German and Portuguese, following your phone by default. Units follow your device region. Dark and light theme. A chime and a buzz the moment a run finishes, both switchable. Your runs, cars and charts stay on your device. An account is only needed for the friends leaderboard. FREE AND PRO Free, forever, with no account: measure 0-100 km/h, or 0-60 mph on an imperial phone, keep one car in your garage, and get your full history, the speed chart, sharing and the friends leaderboard. Launchly PRO unlocks every other speed target, all distance runs up to the quarter mile, unlimited cars, every gauge face and the G-force chart. Monthly or yearly. MEASURE RESPONSIBLY Launchly is a measuring instrument, not an invitation. Only measure on a closed course or a track, never on public roads. Mount your phone securely and keep your eyes where they belong. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://launchlygo.app/privacy-en
