TinyFpvTimer turns your phone into a FPV lap timer. Simply position your phone's camera about 1m/3ft from the start/finish gate, open the app, and go. No connections, calibrations, or accounts required. Launch in under 5 seconds and focus on flying, not setup. Optimized for micro-class whoops on tight indoor courses, TinyFpvTimer delivers reliable lap detection using only your camera. It also works seamlessly with modern digital FPV systems and handles even the fastest passes through the gate. Fly with a friend. Multiplayer lets two pilots share one gate and one phone. The timer learns what each pilot's drone looks like and calls out every lap by name, so you both get your own times out of the same session, and those laps count towards your single-player progress too. Key Features: • Plug-and-Play Timing: No extra hardware or wireless links, just your phone's camera. • Rapid Launch: From app icon to ready in under 5 seconds. • Tight Courses: Optimized for compact tracks and micro drones. • Multiplayer: Fly together on one gate, with every lap timed and called out by pilot name. • AI Lap Detection: On-device AI reads every frame for sharp, reliable lap times, and it all runs on your phone. • Detailed Performance Data: Records your fastest laps and your best streak of consecutive laps (e.g., your top 3 laps flown back to back), with per-track stats and trend graphs on the home screen. • Lap Editor: Correct a misread lap, disable one you didn't want, and check your fastest laps frame by frame. • Hands-Free Control: Start and stop a race with the play/pause button on your Bluetooth headset. • No Monthly Fees or Registration: Fully functional free version, no subscription, no sign-up. TinyFpvTimer is designed for solo training and flying with friends, giving FPV pilots clear feedback on every session. Improve your consistency, chase personal bests, and track your progress over time, all with the convenience of a single app on your phone. Download now and start timing your laps instantly!
