About Smash Time

A squash coach that measures instead of guessing.

What it does

You put one phone on the viewing gallery rail and record a game. Or you upload a video you already have.

A squash court is the same size everywhere: 9.75 by 6.40 metres. You mark six points on one frame, and the app uses them to work out where the camera is. Then it finds both players’ feet in every frame and places them on the court in metres. This runs in the cloud, or on an iPhone itself.

You get where you stood, how far you were from the T, how much of each rally you held it, and how much ground you covered. The coach turns that into two or three findings, each with its number and the rallies it came from.

What it does not do

It does not track the ball. Every measurement comes from the two players and the sound of the court.
It does not keep your footage. A video is uploaded only when you press the button, so it can be measured. It is deleted from the server after seven days. On an iPhone the whole measurement can run on the phone instead, so the video never leaves it.
It has no accounts. There is nothing to sign in to.
It covers squash only. The court’s size is a setting, not code, so padel is planned as the second sport. It is not built yet.

Where it stands

Smash Time is in testing. The web app is live. The iPhone and Android apps are in beta and are not in the stores yet. It is free.

Each measurement had to pass an accuracy check before any coaching was built on it. The checks compare the app with footage a person marked by hand:

Where players stood: passed. Typical error 19 cm, and the right player identified in 96.3% of frames. So the coach talks about where you stood.
Rallies and shots, from the sound: not passed yet. So the coach says nothing that depends on them.

These checks were run on broadcast footage of the Auckland Open 2021, not a club court.

Your data

There is no account. A recording stays on the device that made it until you press the button to upload it. The privacy policy sets out what does and does not leave your device, including what to agree with the other people on court.
