Built by track coaches for coaches and fans. A relay timer for 1–4 teams, the Ultimate Stopwatch, a meters-feet converter and race plans. Free to start; Pro is packed.
Time up to four relay teams on one gun - every handoff, every split, live. One big HANDOFF button per team, splits that turn green or red against your plan, and race plans your athletes can actually read. No more juggling three stopwatches at the exchange zone.
FREE - NO ACCOUNT NEEDED
- Multi-Team Relay Timer: two teams on one gun, a HANDOFF button for each, false start, cancel and undo
- Ultimate Stopwatch: laps for races, plus Reps & Rest in sets of 2 with a rest countdown
- FAT estimate: the NFHS hand-to-FAT conversion, one tap
- Meters to Feet: convert field event marks both ways, rounded down the way the rules require
PRO - FOR PRACTICE AND RACE DAY
Relays
- Up to four relay teams on one gun
- Race-day setup: pick the relay (medleys and shuttle hurdles included) and the meet, name each team, choose its colors and put a runner on every leg from your roster
- Relay Race Plan: set the goal, get the split every leg needs, add a note, then share it as text or print a one-page PDF
- Targets on race day: every split turns green or red the moment it is run
- Lineup comparison: every runner's splits on every leg from your saved races, and the fastest four for your goal
Group timing
- A whole group on one clock: tap each runner's name every time they cross
- Heats with their own start that can overlap - start Heat 2 while Heat 1 is still running
- Missed someone in a close finish? Place them between the runners ahead and behind, clearly marked "edited by coach"
- Results by heat or all together, with every split
Practice
- Reps & Rest up to 50 reps, with a rest countdown that beeps and buzzes GO and ticks at 10 seconds
- Workout builder for ladders and pyramids: every rep its own distance, target and rest, with what's up next shown big on the rest card
- Several heats at once, each with its own rest - start the next heat right from the screen you're on
- Stopwatch race plans from 800 m to 10,000 m with even-pace lap targets, odd first laps built in, indoor tracks of any size
Results
- Save every race and workout to History, then share it as a PDF with your team logo or a spreadsheet
- Show hand times or FAT estimates everywhere - your choice
- Dark mode for bright sun or a dark stadium
Pro comes as a yearly plan or a one-time Pro for life purchase. Every free tool stays free.
