Tools for Athletes & Coaches
18 toolsFor athletes, coaches and referees: a whistle, an electronic scoreboard and a tournament bracket, the beep and Cooper tests, a lap stopwatch, running pace, calories and body fat, jump height and ball speed from video.
Sports & Refereeing
Whistle
A referee whistle with sound: the blast lasts while you hold, signals labeled for your sport, intervals and a WAV download.
Electronic Scoreboard
Score, clock, shot clock, timeouts, fouls and penalties in big digits across the whole screen. The board already knows the rules of twelve sports.
Beep Test and Cooper Test
Audio cues for the 20 m beep test, 15 m PACER and Léger test, a Cooper test timer, tap-to-mark misses, and a class report with VO2max.
Race Timer
Start on a signal, finish by lane or from a mass start: places, gaps, grades and a results sheet — instead of a handful of stopwatches.
Tournament Bracket
Seeded playoffs, round robin with a crosstable, groups that feed a playoff, a draw with a code, schedule and print.
Rep Counter
The camera counts reps by joint angle, says the count out loud and flags short reps separately.
Jump Height
Film the jump on a phone — height comes from flight time, and take-off and landing are visible on the frames and can be corrected by hand.
Ball Speed from Video
Film the shot from the side, tap the ball — the track and the speed work themselves out.

Precise online stopwatch with laps, splits, sparkline and shareable link
Online Chess Clock
Free chess clock for two players on one device — Bullet, Blitz, Rapid, Classical with Fischer, Bronstein and delay modes.

Build an award document and print it — one, or a whole class at once.
Reaction Time Test
Measure your reaction speed in visual, audio, and reflex modes with millisecond precision.
GPS Speedometer
See your real speed from GPS: max, average, distance and track export. Check what your dashboard reads against true speed. No install.
GPX Viewer and Converter
Open GPX, KML, KMZ, FIT or TCX files on a map with an elevation profile and climbs, draw a route, and save it for Garmin, Strava or Google Earth.
Tally Counter
Count events with one tap: people at the door, knitting rows, training laps. Several categories at once, step, target, undo, pace and CSV export.
