Race Lap Counter
Give every racer their own tap button. Live lap count, last lap, best lap, and gap-to-leader update per racer, with a finish banner the instant someone hits the target lap count.

How to play
- Type each racer's name, one per line, and set an optional target lap count.
- Tap Start Race, then tap a racer's Lap button every time that racer completes a lap.
- Watch each racer's live lap count, last lap, best lap, and gap-to-leader update after every tap.
- The finish banner fires the instant a racer hits the target; use Show Finish Order anytime for a full ranked list, and each racer's own Undo button fixes a mis-tap.
Race Lap Counter gives every competitor their own giant tap button for track days, karting, RC racing, or any repeated-lap event with several racers going at once. Type in your roster, set an optional target lap count, and tap a racer's button every time they cross the line — that tap is never debounced, so a pack of close finishers all still get counted accurately. Each racer's card shows a live lap count, their last lap time, their best lap of the session, and a gap-to-leader that shows a time difference for racers on the same lap or a laps-down count for anyone behind. The moment any racer reaches the target lap count a finish banner celebrates them while everyone else keeps racing, and Undo on any racer's card removes just their last lap without touching anyone else's count.
Frequently asked questions
- How is this different from the Relay Race Timer?
- Relay Race Timer times ONE team running sequential legs, with a single handoff button that advances through a fixed number of runners. Race Lap Counter is the opposite shape: several racers competing concurrently, each with their own button, each lapping independently toward a shared target — there's no handoff or leg order involved.
- What does the gap-to-leader number actually mean?
- If a racer is on the same lap as the leader, the gap is the time difference between their total lap times so far. If they're behind on lap count, the gap shows as laps-down instead of a time difference, since comparing raw times across different lap counts would be misleading.
- Does tapping a racer's Lap button too fast risk missing a lap?
- No — every tap is counted, with no debounce or cooldown on the lap button, because a real lap crossing deserves a real count even if a fast racer laps in quick succession.
