A field tool for measuring the height of trees, poles, and structures using a rope, a known distance, and your phone's tilt sensor.
Instructions
- Measure your eye height and enter it as Eye Height.

- Tap Done to calculate the height.
- Measure your eye height using the marked end of the rope. Enter it as Eye Height.
- Place the rope stake at the base of the object. Lay the rope along the ground.
- Stand at the 10 ft, 30 ft, or 60 ft mark. Enter that distance as Distance.
- Tap Enable Sensors below, then rotate your phone to Landscape Mode (auto-rotate must be on).
