Find out what your car really does. Launchly is a GPS acceleration timer for your car: a 0-60 timer, a 0-100 timer and a quarter mile drag timer in one app. It measures every run 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 meter or drag 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 acceleration test 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. FRIENDS, COUNTRY AND WORLD 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. Then see where you stand in your country and in the world. A run you share can go on the public country and world leaderboards too, under your username only, and only when you switch it on. 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 leaderboards. FREE AND PRO Free, forever, with no account: the 0-100 km/h timer, or the 0-60 mph timer on an imperial phone, one car in your garage, your full history, the speed chart, sharing and every 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, a stopwatch for your car, 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.

Add your car's power and torque. Every run keeps them, so you always know what it was measured with. Calibration finishes sooner, and the gauge reads 0 while the car is standing still. Country and world boards open on the top 10. Tap Show more to see up to 50, and your own place stays in view below. The friends leaderboard shows each car on a single row. ### 1.2.4 — 2026-10-14 Country and world rankings. The leaderboard now has three levels: your friends, your country and the whole world. Sharing a run lets you put it on the country and world board too, under your username only. Sprint times are now calibrated against GPS position instead of GPS speed, so two phones agree far more closely. Permission prompts now appear in your language. ### 1.2.2 — 2026-09-05 A big update since the first version. Distance runs: 100/200/400 m and the 1/8 and 1/4 mile, with trap speed. Imperial units: switch to mph and run 0-60 mph as its own finish line. A rebuilt friends leaderboard with a podium, grouped per person and per car. New: a chime and a buzz the moment a run finishes, both switchable. Launchly now also speaks German and Portuguese, and follows your phone's language. Plus quicker calibration, working notifications and a long list of fixes. ### 1.0.0 — 2026-07-22 No release notes. ## Apps similar to Launchly | App | Rating | Price | Category | | --- | --- | --- | --- | | [Vroomist](https://appshunter.io/ios/app/vroomist/id6759291301) | — | Free | Utilities | | [Accel Timer: GPS Speedometer](https://appshunter.io/ios/app/accel-timer-gps-speedometer/id6764881084) | — | Free | Utilities | | [Devim GPS: 0-60 and Drag Timer](https://appshunter.io/ios/app/devim-gps-0-60-and-drag-timer/id6761691878) | 3.0 (1) | Free | Utilities | | [ZeroTo: 0-60 & Drag Timer](https://appshunter.io/ios/app/zeroto-0-60-and-drag-timer/id6816867700) | — | Free | Utilities | | [Speed Timer - GPS Speedometer](https://appshunter.io/ios/app/speed-timer-gps-speedometer/id6761398337) | — | Free | Utilities | | [PitLaunch](https://appshunter.io/ios/app/pitlaunch/id6783879705) | — | Free | Utilities | ## Related topics [car performance tracker](https://appshunter.io/ios/topics/car-performance-tracker) · [0-60 time](https://appshunter.io/ios/topics/0-60-time) · [0-60 performance](https://appshunter.io/ios/topics/0-60-performance) · [0-60 car](https://appshunter.io/ios/topics/0-60-car) · [quarter mile](https://appshunter.io/ios/topics/quarter-mile) · [0-60 speed](https://appshunter.io/ios/topics/0-60-speed) · [apps for vehicle speed testing](https://appshunter.io/ios/topics/apps-for-vehicle-speed-testing) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
