Race Stats vs Speed Timer

Your phone is the drag strip — and now the race track too. Race Stats turns your iPhone into a GPS performance timer for cars and motorcycles. Time 0-100 km/h and quarter-mile runs, watch your lean angle live through every corner, and log lap times — no extra hardware needed. NEW FOR RIDERS • Live lean angle for both sides, with a rider that leans with you • Max left and max right lean tracked separately, every session • Lap timer: set your start/finish line and ride — laps are timed automatically • Spoken lap times and gap to your best, straight to your headset • Lap map of your best lap, coloured by lean angle or speed • Share a session slip with your best lap, map and max lean • Best lap, last lap and the gap to your best • A garage for cars and motorcycles, with lean records per bike DRAG & ACCELERATION TIMING • 0-100 km/h (0-60 mph), 0-160, 1/8 mile, ¼ mile, 1 mile • Custom speed ranges and rolling starts, e.g. 60-100 km/h (Pro) • Auto-arm when stopped, auto-start the moment you launch • GPS fused with the accelerometer for precise launch and finish detection • Weather-corrected results (density altitude), like a real drag strip • Estimated wheel horsepower from your run • Personal best alerts on every run HISTORY & SHARING • Every run saved with its speed curve • Personal bests flagged automatically • Compare two runs side by side • Share a branded timing slip with your crew • Export full telemetry as CSV MORE • Real-time g-force meter: launch, braking and cornering grip • Global leaderboards per benchmark — see where you rank • Maintenance reminders: insurance, road tax, oil and service dates • Works with external Bluetooth GPS receivers (RaceBox, NMEA) for 10-25 Hz timing • Metric and imperial units • Your runs and garage are stored on your device FREE AND PRO Timing your runs and the live lean angle gauge are free. Race Stats Pro unlocks the lap timer, saved track sessions with lap maps, the g-force meter, the full garage and run history, run comparison, CSV export and external GPS support. Always obey the law and ride and drive responsibly. Use Race Stats only on closed courses, tracks and drag strips, and mount your phone securely before you set off.

Speed Timer is a precision GPS-based acceleration measurement tool designed for car enthusiasts, automotive journalists, and anyone who wants to know their vehicle's real-world performance. MEASURE ANY SPEED RANGE Set custom start and end speeds or use built-in presets like 0-100, 0-200, 100-200, and 60-130 km/h. Switch between km/h and mph units instantly. HOW IT WORKS 1. Select your speed range 2. Tap Start to arm the measurement 3. Accelerate — the app automatically detects when you cross the start speed 4. Timer stops precisely when you reach the target speed 5. View your corrected time with detailed analysis PRECISION ENGINEERING - Dual EMA (Exponential Moving Average) filtering for noise-free readings - Sub-sample threshold crossing interpolation for accurate timing - Automatic GPS bias and filter lag correction - Confidence rating (High / Medium / Low) based on GPS accuracy and acceleration data REAL-TIME SPEED GAUGE A beautifully designed gauge displays your current speed with smooth animations, color-coded status indicators, and live elapsed time during measurement. DETAILED ANALYTICS Every measurement includes: - Speed vs Time chart - Acceleration vs Time chart - Distance vs Time chart - Speed vs Distance chart - Corrected and raw times - Maximum speed reached - Average acceleration - GPS accuracy metrics COMPARE RUNS Side-by-side comparison of your last two runs with overlay speed charts and a detailed metrics table showing which run was faster. HISTORY & EXPORT - All measurements saved locally with up to 200 records - Swipe to delete unwanted records - Export individual runs as CSV - Export full history as JSON backup - Share data via any app CUSTOMIZABLE - Dark and light themes - km/h or mph units - Haptic feedback toggle - Advanced tuning: deadband, snap-to-zero, EMA filter alphas, correction bias offset PRIVACY FIRST Speed Timer works entirely offline. Your location data is used only for speed calculation and is never uploaded, shared, or stored beyond your device. Note: GPS accuracy depends on device hardware and environmental conditions. For best results, use in open areas with clear sky visibility. Speed Timer is intended for use on private roads and closed courses only.
