OverLap – FPV Drone Lap Timer

Lap times from your camera

Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.

Time every lap with just your iPhone camera: no transponder, nothing on the drone. Import your goggle DVR, export it with a stats overlay and follow your progress. OverLap turns your iPhone into a lap timer for FPV drones. Stand the phone beside the gate, in line with it, and fly: the camera sees the drone cross and times every lap. No transponder, no timing system, no setup on the drone. Made for FPV pilots who train on a track, from tiny whoops in the living room to 5" quads at the field, alone or with friends. TIME EVERY LAP • Camera timing: take off when you're ready, the phone detects each crossing of the gate and calls out every lap • Easy setup: pick the rear lens (0.5×, 1× or 2×), fit the detection window to the gate or draw the zone with a finger • Goggle DVR: import the recording from your goggles, OverLap lines it up with the race through a code shown on the phone • Video export with a stats overlay (Tower style) for sharing • Race formats: free practice, a number of laps or a time limit • Lap statistics: best lap, average and your best laps in a row, live on the race screen, with a callout for each new best • Tracks with a goal (best lap or best laps in a row) • Track maps: import a track drawn in tinylaps, see it in 3D or in augmented reality on your floor, and fly through it • Apple Watch: start and stop the race from your wrist, see your last and best laps and the lap count, pick the pack with the Digital Crown • Hangar: your drones beside your packs, picked for each race, with each drone's best laps per track • Battery packs: numbered packs, printable QR labels scanned by the camera, rotation, C-rating and air time per pack; switch packs between races without redoing the setup • Streak and stats: your race days, air time, laps, personal bests and records OVERLAP PRO, PAID ONCE One purchase unlocks everything, for good, shared with your family. No subscription. • Sectors: split each lap into sectors from your goggle footage and see where the time goes • Battery from the OSD of analog and HDZero recordings: mAh and voltage per lap, pack health, endurance per pack and drone, and when to land • Drone compare: your laps by camera angle and before and after each build change • Five more overlay styles (Telemetry, Numeral, Ticker, Broadcast, OSD), previewable before you buy • Exports without the watermark • CSV export of your laps WHAT YOU NEED • An iPhone • Optional: an Apple Watch, and goggles that record DVR footage PRIVATE BY DESIGN No account, no ads, no data collected. Your races stay on your devices and sync only through your own private iCloud; the camera is only used on the device.
