Measure which boule is closest to the jack — from a photo.
- Once: choose your phone in Settings.
- Tap Measure, hold the phone about 1 m above the jack and tap the button. Then slide the phone 30 cm sideways, slowly, keeping the jack in the middle of the screen. No ring needed: the ground itself, seen from two places, gives the distances.
- Check the circles the app draws. Drag any that are off, or add missing balls.
- Close calls are flagged “too close to call” with the reason. They get rarer as the app learns your phone’s camera over the first few sweeps.
