Best 0-60 and 0-100 acceleration timer apps in 2026
To time 0-100 km/h, 100-200 km/h or a quarter mile with nothing but your phone, LM - Vehicle Analysis, which fuses GPS with the accelerometer. For a GPS performance meter with a leaderboard and video overlays, dragy Connect, which needs the dragy device. For the same kind of equipment car makers and magazines use, VBOX Sport Performance Test, which needs the VBOX Sport. Every one of them is meant for a closed track, never a public road. Full breakdown below.
How we picked: an acceleration timer is only as good as its data and the place you use it. We read each developer’s own App Store description for which intervals it measures, whether it works on the phone alone or needs an external GPS unit, and how it shares results.
Time 0-100 with only your phone
LM - Vehicle Analysis, also called Launchmeter, is a vehicle motion data logger that uses GPS and the phone’s sensors together. It times the speed ranges 0-60, 0-100, 50-150, 100-200 and 0-200 km/h, and the quarter mile of 402 metres with elapsed time and trap speed. It also measures road gradient so you can judge whether a run is valid, shows a GPS speedometer with maximum speed, distance and trip time, keeps data for more than one vehicle and exports a statistics card to share. Its own rule is clear: use it on closed test tracks or private facilities, with a passenger operating the phone.
A dedicated GPS performance meter
dragy Connect is the app for the dragy GPS performance meter, and it does not time runs without the device. With it you track 0-60, 60-130 and 0-130 mph and the quarter and half mile, share results on a leaderboard and export videos with a real-time speedometer and a performance report. VBOX Sport Performance Test pairs over Bluetooth with Racelogic’s VBOX Sport, a GPS receiver that samples far more often than a phone, and measures 0-60, quarter mile with trap speed, braking and VMAX; without the unit it runs only in demo mode.
Phone or box: which to choose
A phone-only app is the quickest way to start, since there is nothing to buy or charge; LM makes up for the phone’s slower GPS by fusing it with the accelerometer. A dedicated GPS unit such as dragy or VBOX Sport records position much more often, which matters when you compare fractions of a second. Whatever you use, time runs only where it is allowed, on a closed course. To read what the engine itself reports, see car diagnostics apps.

Frequently asked questions
Can I measure 0-100 km/h with just my phone?
Yes. LM - Vehicle Analysis times 0-100 km/h and other ranges with the phone’s GPS and accelerometer, with no extra hardware, on closed tracks only.
Do dragy and VBOX apps work without their devices?
No. dragy Connect needs the dragy device for performance testing, and VBOX Sport Performance Test needs the VBOX Sport; without it the app runs only in demo mode.
Which app times a quarter mile with trap speed?
LM - Vehicle Analysis and VBOX Sport Performance Test both report quarter-mile time with trap speed, and dragy Connect tracks the quarter and half mile.
