The tape test tape first, then the app

  1. Take the photo with something you know the length of in the shot.
  2. Mark both ends of that known thing, and tell the app what it is.
  3. Read "the whole photo is X across". Believable? If not, the reference is wrong. Fix it before you measure.
  4. Measure with the tape. Write it down. Then read the app.
Case Frame reads OK? Tape App Diff
1   Flat, facing you — fence, gate, doorTape in the shot. If this is off, nothing else works.
2   Angled away — a path, a bed edgeHow fast it goes wrong off-square.
3   Further off than the referenceShould be wrong. Did confidence drop?
4   Break it — mark a brick, call it 6 ftLine should look ridiculous. Would you have spotted it?

Measuring on the map never run on hardware

For things too far apart to fit in one photo. It uses GPS, not the photo. Pace or tape the same gap and compare — nobody has ever checked this.

What Tape / paced App ± shown Diff
Pin to pin, both snapped
Pin to a free point
Two free points
Tapped the track between two pins
