Stopwatch · 05:52 at the gallops
Time the work. Read the pace.
A clock for every horse in the string, a split at the distance you choose, and the speed of every split the moment you tap. No account, nothing to install, and once it has loaded, no signal needed.
Illustration of a stopwatch showing a sample run: Copper Lantern, a four-furlong breeze split every furlong in 13.62, 12.84, 12.31 and 11.98 seconds, stopped at 50.98 seconds, an average of 56.5 kilometres per hour.
Several horses at once
Clock the whole string. Every horse on its own clock.
Add a timer for each horse in the lot. Start, split, pause or stop one and the others never notice. When the string pulls up, Save all stops every running clock at one shared instant and keeps the morning together.
Stopped together means stopped together: every clock is read at the same instant, so no horse gains a hundredth waiting its turn.
Splits · 1f to 8f
Tap at every pole. Read the pace before the next.
Each tap records that split's time, the running total and the speed over it, and colours the split by pace in five fixed bands. Full Hisani Gold starts at 66 km/h.
| Mark | Split | Time elapsed | Speed |
|---|---|---|---|
| 1f | 13.62 | 00:13.62 | 52.9 km/h32.8 mph |

The same run, on paper
Every split, kept three ways. Its own time, the total, its speed.
The clock reads minutes, seconds and hundredths and cuts rather than rounds: 50.989 seconds reads 00:50.98. The milliseconds underneath are kept, so every speed is worked out from the measured time.
| Mark | Split | Time elapsed | Speed |

Focus Mode · phone and tablet
Eyes on the horse. Thumb on the glass.
On a phone or tablet, Focus Mode turns one timer into a full-screen slab you can work without looking down. Tap the surface to start or record a split; double-tap or hold to stop. Pause and distance stay in the top band.
- The whole surface is the button.
- One surface starts the run, splits it, resumes it and saves it when it's done.
- Double-tap or hold to stop.
- A double-tap or half-second hold stops at the first press instant. A single tap records a split or resumes.
- Made for glare.
- Deep ink in both appearances, a sound for every action, a vibration where the phone allows it, and a request to keep the screen awake.
Practice · nothing is saved
Try it: tap the slab, or press Space.
History and sharing
Send the morning before you leave the rail.
Copy or share one run, or a whole day, as plain text for any message. At a desk, Timing history adds search, filters, four summary figures and CSV export.
History doesn't sync. A run timed on your phone stays on your phone for seven rolling days.
- With an account
- Stopwatch suggests names from My Horses as you type. Only the name is kept with the run.
- In a Stable
- Save a finished session to a Stable horse and it joins that horse's timeline, beyond the seven days.

Out of signal
Signal drops. Timing doesn't. And a crash never invents time.
App crashed at 00:37.40Back, paused at 00:35.00Not counted · 2.40 s
Once Stopwatch has loaded, it times, splits and saves with no connection. A running timer is saved to the device at least every five seconds, and again the moment the screen hides. If the app is closed or crashes mid-run, the timer comes back paused at its last saved time, without the time it didn't see, and says so:
The first visit needs a connection, so open Stopwatch once before you head out.
Timing was interrupted while the app was suspended; 1 timer(s) paused at the last saved time.
Straight answers
What Stopwatch does, and what it doesn't.
Do I need an account?
No. Open Stopwatch and start timing. Signing in adds name suggestions from My Horses and, inside a Stable, saving a session to a Stable horse.
Does it work without signal?
Yes, once it has loaded on your device. The first visit needs a connection.
Does it time automatically?
No. A GPS track does not time the horse. You time by hand, with a tap at each pole, so every time is as good as the thumb that took it.
Does my history sync between my phone and my laptop?
No. Saved runs stay on the device that timed them for seven rolling days. A session saved to a Stable horse is the exception: it stays on that horse's record.
How long can a split be?
From 1f to 8f (200 m to 1,600 m). Choose the distance before each split; changing it later doesn't rewrite the splits already taken.
Is there an app to download?
No. Stopwatch runs in the browser on a phone, tablet or computer, and you can add it to your Home Screen.
