SplitShift Race Timer

SplitShift turns your Android phone into a focused track-day recorder for closed-course motorsport. TIME EVERY RUN Capture drag launches, 0-100 km/h acceleration, quarter-mile times, reaction estimates, circuit laps, and sector splits using your phone's GPS. RECORD THE COMPLETE SESSION Pair synchronized video with speed, G-force, route, lap, and sector data. Review the session in the app, then export a clean MP4 with your chosen telemetry overlay. BUILD YOUR GARAGE Keep vehicles and modifications organized so every result has the right context. Mark a primary car, document changes, and compare sessions over time. CONNECT TRACK HARDWARE Use the phone's sensors, a compatible Bluetooth NMEA GPS receiver, or a paired ELM327 OBD-II adapter. Available vehicle data such as RPM and throttle can be added to recordings. PRIVATE BY DEFAULT Your vehicles, location traces, telemetry, and recordings stay on your device. SplitShift has no advertising or analytics SDKs. Data leaves the app only when you choose an export or share destination. IMPORTANT SAFETY NOTICE SplitShift is designed only for closed, controlled racing circuits. Secure the phone before moving and never interact with it while driving. GPS, camera, and sensor timing are estimates and are not a replacement for official timing or safety equipment.
