Latest release
What’s New
New in v2.19: • External keyboard support Plug in a USB or Bluetooth keyboard or numpad and type distances straight in. 0-9 enter a distance, Backspace clears the current target, "." clears all. On SPA, "/" swaps distance and slope, "-" and "+" set the sign. • More screen for your numbers With a keyboard connected the on-screen keypad steps aside, so the readouts get bigger and history shows more targets. Prefer the keypad? Settings > On-Screen Keypad keeps it.
