TapSplit vs Run This Stopwatch

TapSplit is a no-nonsense stopwatch built for coaches and athletes who need to trust their timing. TAP ANYWHERE — START, LAP, RESUME The whole screen is your button. Tap to start, tap for every lap (zero debounce — every touch counts), tap to resume after a stop. Each tap fires a crisp haptic. No tiny targets, no missed splits — just keep your eyes on the athlete. LAP & SPLIT AT A GLANCE See each lap time and its cumulative split side by side, with a running BEST / AVERAGE / WORST strip so trends jump out at a glance. PLAN YOUR SETS Save a set like 8×100m on 1:30 and load it onto the stopwatch. TapSplit counts the reps and shows live "Rep 3 of 8" progress, so you just tap the splits — no counting in your head. Give the set a send-off interval and it counts down to your next rep during the rest, buzzing when it's time to go — a real interval trainer. Keep a reusable library of your go-to sets, each with its own note. TIME YOUR WHOLE SQUAD It all happens on one Stopwatch screen. Start with one big tap-anywhere clock, then tap + to add another stopwatch whenever you need it — even while the first one runs — up to six on one screen. Tap a stopwatch's name to pick an athlete from your saved list, or leave it unnamed. Start them all together for a mass start, or each one as they go. Every run saves as its own session. HEAR EVERY LAP Turn on Speak times and TapSplit calls each lap aloud through your earbud, on every stopwatch — with the athlete's name or number when you time more than one — so your eyes stay on the water. Pick Normal, Fast, or Faster in Speaking speed. STROKE RATE IN A FEW TAPS Press and hold while you count a few cycles — strokes, steps, or pedal strokes — and release. TapSplit times the hold and gives you the rate per minute. Measure mid-session and it pairs with the lap you took it on, so rate sits right beside that length's split. REVIEW EVERYTHING IN HISTORY Every session is saved the moment you start — there's no Save button to forget. Filter by stopwatch, set, or athlete, search your sessions, and browse them grouped by day. Rename sessions and add notes. ROCK-SOLID ACCURACY TapSplit runs on a monotonic clock that never drifts — accurate across stop and resume, and it keeps running even when your phone is locked or the app is in the background.

One shared clock. Every phone in sync. Time a race with the devices already in your volunteers' pockets. No account, no login, just the code from your race director. The start only fires once, so the clock should only exist once. Run This Stopwatch keeps the official race clock on the server, and every phone at the course reads the same time to the second. Start the clock when the race starts, tap Record as runners cross, and type the bib now or tie it on later when the rush clears. AT THE FINISH LINE • One big Record button, built for fast taps in gloves • Times are stamped by the click so two devices never disagree • Tap a bib from the roster and the runner's name fills in automatically • Missed a bib in the rush? Record the time anyway. Rows that still need a bib stay flagged until someone ties them on • A running count of finishes, and how many still need bibs ONE CLOCK, MANY DEVICES • A two-person finish line sees each other's taps within seconds • Fix a time, bib, or name from any device, and every device updates • Show newest finishes first, or finish order, per device • Stopping the clock pauses it for everyone, and you can still record late finishers SPLITS, NOT JUST THE FINISH • Your director can set up checkpoints along the course. Pick the one you are standing at • Put a phone at mile 5 and another at the finish, and both feed the same race WHEN THE DUST SETTLES • Every tap appears live in your race director's dashboard • Export the full list as a CSV, or email it in one tap • Your director can publish finish times straight to the event's results on Run This MADE FOR VOLUNTEERS • No account and no login. Just the code from your race director. • Everyone timing the race uses the same code • Dark mode for when it's your vibe Run This Stopwatch works with events that use Run This for registration. You will need a stopwatch code from your race director to get started.
