Read full description

A protractor, bubble level, tape measure, ruler and room-planning toolkit in your pocket. Digital Protractor & Level brings 15 tools together with large readings, familiar instruments and a quick tool selector. Choose any tool as your default at launch. Now in English, Spanish, French and German. ANGLES & LEVELS • Protractor: read angles with a realistic dial and clear numerical display. • Level: a traditional bubble vial with degrees, percent slope and rise per 12. • 4 Corners: a bullseye surface level for tabletops and other flat surfaces. • Photo Angle: choose a photo and drag the corner and endpoints to measure an angle. • Camera Level: use on-screen alignment guides over the live camera. • Compass & Tilt: check direction and inclination. MEASURE & PLAN • Tape Measure: place a start and end point in augmented reality, with a bold measurement line and visible point markers. Chain segments, capture dimensions and save measurements with Expanded Toolkit. • Ruler: a full-height, calibrated on-screen ruler in metric or imperial units, with a drag handle that stays clear of the controls. • Feet & Inches: calculate fractions, convert metric lengths, add or subtract dimensions, multiply, divide and find equal spacing. • Height: mark a base and top to estimate vertical height. • Area: outline a flat surface to estimate its area. • Floor Plan: enter wall lengths or mark floor corners, then save and share a plan. • Room Layout: scan a room with LiDAR on a supported iPhone. Export USDZ, OBJ, SVG and JSON files to a computer for compatible 3D, drawing and rendering software.
