Stringing machines · team rooms

Know the machine is free before you walk over.

Crosses keeps every stringing machine your team shares on one live screen. Hold a window when you need one, tap the machine's tag to start, and every job logs itself.

The room

Status nobody has to maintain.

State comes from what people are doing on the machines. It changes the second someone finishes: no sign-up sheet, no asking the group chat.

One accent, one meaning

Orange marks what is live right now, or what is yours. Nothing else is ever orange, so the room reads the same way every time you look at it.

Hold a window

Request a time on a specific machine and get a reminder before it starts. Your own time is hatched, so you can pick it out of a full day at a glance.

Finish and free it

Tap done and the machine frees for everyone immediately. The job drops into history: racquet, string, tension, who strung it, and when.

A session

Three moves, every time.

The same three, which is why they're on the mark. Tap, string, log.

01 · Tap

Hold your phone to the tag on the machine. Crosses opens on it and claims it for you, even from the lock screen.

02 · String

A timer runs while you work and rides the Lock Screen. Extend it if the job is bigger than you thought.

03 · Log

Done frees the machine for the room the same second, and writes the job into the room's history.

Machine tags

One tag per machine.

Pair a sticker to a machine once, from inside the app. After that the tag is the shortest path into a session.

With Crosses installed, the tap opens the app straight to that machine and starts the session.
Without it, the same tag opens a page naming the machine: a guest stringer or an Android phone still lands somewhere useful.
