Car Timer vs Launchmeter

Measure your vehicle's performance with acceleration tests, braking measurements, top speed tracking and drag race timing — all from your phone. Whether you're comparing modifications, testing different vehicles or simply satisfying your curiosity, Car Timer helps you record and analyze performance quickly and accurately. Features • Acceleration tests (0-50 km/h, 0-100 km/h, 0-30 mph, 0-60 mph and custom speed ranges) • Distance tests (200 m, 400 m, 800 m, 1/8 mile, 1/4 mile and custom distances) • Braking distance measurements • Top speed tracking • Performance history and result comparison • Share results with friends and fellow enthusiasts • Metric and imperial units • Dark mode and customization options Car Timer uses GPS-based speed measurements together with interpolation techniques to estimate results more accurately than raw GPS updates alone. Always obey local traffic laws, posted speed limits and road conditions. Perform testing only when it is safe and legal to do so. Questions, suggestions or bug reports? contact@codingfy.com

Launchmeter turns your iPhone into a performance meter. Find a safe, open space and measure your car's 0-60 mph time with one tap. ACCELERATION TIMING & SPLITS • 3-second countdown, then timing starts automatically when you pull away • Time several runs at once — 0-30, 0-60 and 0-100 mph — and set your own targets • Every split is compared with your personal best: green when faster, red when slower GPS + MOTION-SENSOR FUSION • Speed fuses GPS with your iPhone's accelerometer and gyroscope: accurate GPS gets more weight, the sensors fill the gaps between fixes • The launch moment is detected by the accelerometer, so the start isn't delayed by GPS updates • Hand shakes and road bumps are filtered out, so readings stay steady EVERYTHING AT A GLANCE • Big three-digit speed and a segmented speed bar • Friction circle for longitudinal and lateral G, plus a live G-force trace • Grade meter — tap to zero • Local temperature, humidity and pressure from Apple Weather, plus your iPhone's barometer RUNS & ROUTES SAVED • Speed and G-force traces, splits and route are saved on your iPhone for every run • Drag across the charts to replay any moment • Routes keep recording with the screen locked LAUNCHMETER PRO (OPTIONAL, ONE-TIME PURCHASE) • Weather-corrected times: air density, density altitude and SAE J1349 correction so runs compare fairly across seasons and altitude • Export CSV data and GPX tracks • Share cards with your splits and speed trace • Multiple cars: log and compare runs per car Everything else stays free forever. PRIVACY Your runs stay on your iPhone and are never uploaded. Location is only used to measure speed, record routes and look up local weather. SAFETY Only test on closed courses or where it's safe and legal. Obey traffic laws and never use your phone while driving. Continuous GPS use during a run increases battery drain. Results depend on GPS signal and phone mounting and are for reference.
