Fast Distance Measure

Fast Distance is a smart camera rangefinder tool that lets you measure distance and object height instantly using your smartphone camera and motion sensors!

No tape measure or bulky equipment needed. Fast Distance combines your camera view with trigonometric calculations based on device tilt and height to deliver fast and reliable estimates.

Key Features:
- Real-time Distance Measure: Aim at the base of any target on the floor to calculate distance instantly.
- Height Measure Mode: Measure the ground point and the top point consecutively to determine the total height.
- Reticle Fine Adjustment: Drag the crosshair up and down for precise alignment, or double tap to reset.
- Value Lock & Capture: Lock measured readings on screen and take snapshots to save or share.
- Sensor Calibration: Recalibrate internal tilt sensors easily for enhanced accuracy.
- Metric & Imperial Units: Effortlessly toggle between meters (m) and feet (ft).

How to Use:
1. Set your device camera height (from floor to phone) while standing naturally.
2. Aim the crosshair at the ground where the target touches the floor, not the top.
3. Read the instant calculated distance and press Lock to freeze the reading.

※ Measure targets at least 1m (3ft) away for best results. Optimal accuracy: 1–5m. Usable range: up to 10m.

Ideal for room planning, interior design, furniture arrangement, and quick outdoor estimation!
