Your Yarbo knows more than it tells you.
Yardstick records what your machine actually did — where it lost its position, where it stopped, which corner of the garden it never finishes — and shows it to you on a map of your own yard. It runs on your computer, on your own network.
The app shows you a percentage. This shows you the problem.
A robotic mower publishes far more about itself than any app displays: satellite quality, heading confidence, correction age, blade currents, every cell temperature in the battery. All of it arrives on your network and then disappears, because nothing is listening.
Yardstick listens, keeps it, and turns it into sentences you can act on.
Not "coverage was 94%". A place, a size, a direction from the dock, and how often it has gone wrong — so you know whether to move the route or cut a branch.
What it shows you
Where the position degrades
A map of your yard coloured by how well the machine was positioned there, across every session — not one run, all of them.
Trouble spots, in words
Places that keep going wrong, grouped by what you would do about them: sky view, or the correction stream from your Data Center.
Coverage against the plan
Recorded area beside the job's real size, so a patch is never mistaken for the whole yard.
Battery and blade health
All six cell temperatures and both blade currents over time, so a cell drifting hot shows up months before it strands you.
Alerts that do not cry wolf
Stuck, stopped in the yard, left the map, cannot get home. Every threshold set by replaying real recordings — roughly one alert every three hours, and each one a real event.
A wall display
A full-screen summary for a television: progress, battery, speed, signal. Alerts take over the screen in red.
It runs where your robot is
Yardstick talks to your Data Center directly over your own network. It does not depend on anybody's cloud being up — which matters, because that is the part that goes down. When the app loses your machine, Yardstick usually carries on recording.
The recordings live in a single database file on your computer. Nothing is kept anywhere else.
What you need
- A Yarbo with its Data Center on your network.
- A computer on that same network, left running. Windows 10 or 11 has a one-click installer. macOS and Linux use a setup script that does the same work — it finds or installs a suitable Python, then registers Yardstick as a login agent or a systemd service.
- It has to stay awake. A sleeping computer records nothing — this is the one thing people get caught by. On Windows and Linux it runs before anyone logs in; on macOS it records while you are logged in and the machine is awake.
