Why it exists

Plenty of good cars came with a dashboard that tells you very little. A speedometer that reads a few miles an hour high, no idea what the limit is, and a wealth of engine data locked behind a diagnostic port nobody plugs anything into.

Meanwhile, most people already own a tablet or an old phone. BTYSHU joins the two up.

What we care about

• Open hardware. Nothing to buy from us and no approved device list. Standard parts, open standards and open map data.
• Working offline. A car isn't always somewhere with signal, so the parts that matter don't depend on it.
• Respect for the driver. No nagging, no alarms, and nothing on screen that isn't backed by real data.
