Relay Race Timer
Time every relay lane with one giant handoff button per leg. Splits are recorded exactly at each handoff, the total always matches the sum of legs, and a podium ranks every team.

How to play
- List your teams (1-8 lanes) and set how many runners/legs each relay has, then tap Set Up Lanes.
- Tap a lane's button once to start its clock for the first runner.
- Tap the same button at every handoff — it records that leg's exact split time and starts the next leg instantly.
- After the last leg's handoff the lane locks in its total time; tap Reveal Podium to rank every finished team by total time.
List your teams and how many runners are in each relay, then hand one phone or tablet per lane to a judge, or run every lane from one screen side by side. Tapping a lane's button starts its clock, and every following tap is a handoff: it records the exact time that leg just took, shows it as a split chip, and instantly starts timing the next runner with no gap or overlap. The final tap on the last leg locks in the lane's total time, and that total is always the exact sum of every recorded split, so there's never a mismatch between the splits and the finish time. Once every lane you care about has finished, tap Reveal Podium to rank every team from fastest total time to slowest.
Frequently asked questions
- Does the total race time always match the sum of the leg splits?
- Yes. Every handoff tap records the exact elapsed time since the previous handoff as that leg's split, and the final total is calculated as the exact sum of all recorded splits — never a separate, possibly mismatched clock reading.
- Can one lane's handoff button affect the other lanes?
- No. Each lane's start, handoff, and finish taps are tracked completely independently, so timing one team's runners never pauses, resets, or interferes with any other lane's clock.
- What if I tap the handoff button twice very quickly by accident?
- Each lane has its own guard against double-recording a single handoff, so an accidental double-tap won't create a duplicate split or skip a runner's leg.
