Read full descriptionHide full description
A protractor, bubble level, tape measure, ruler and room-planning toolkit in your pocket. Digital Protractor & Level brings 14 tools together with large readings, familiar instruments and a quick tool selector. Choose any tool as your default at launch. ANGLES & LEVELS • Protractor: read angles with a realistic dial and clear numerical display. • Level: a traditional bubble vial with a tilt reading. • 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: measure small objects against the screen, with calibration and metric or imperial units. • 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. OBJ exports contain simplified geometry. • TV Sizer: preview a selected screen size on a wall. • Magnetic Field: view nearby magnetic field strength. QUICK ACCESS Switch tools from the Tools button, revisit recent tools, set your preferred startup tool, and organize saved measurements. Portrait and landscape layouts keep controls within reach. FREE & PAID ACCESS Use the basic Protractor, Level, Ruler and single-line Tape Measure free. Opening a tool preview is free; paid tools and actions show the available purchase options when you use them. Expanded Toolkit unlocks all paid features. Choose $1.99 per month, $4.99 every three months, or a $14.99 one-time lifetime purchase in the U.S. Prices vary by country and are shown before purchase. Monthly and three-month subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Manage or cancel subscriptions in your App Store account settings. Lifetime does not renew. Restore Purchases is available in the app. Existing Original Tools buyers keep the tools and features included in their original purchase. Expanded Toolkit is an optional upgrade for the additional tools. DEVICE & MEASUREMENT NOTES AR measurements are estimates and depend on lighting, surfaces and tracking. Room scanning requires a LiDAR-equipped iPhone. Camera Level displays virtual guides; it does not project a laser. Magnetic Field is not a dependable wire or stud detector. Photo angles can be affected by perspective. Check critical measurements with appropriate physical tools. No account or advertising. Photos, scans and saved measurements stay on your device unless you choose to share them. Camera access supports camera and AR tools; optional location access supports true north. Purchases and restores require internet access. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Digital Protractor & Level's advantage is update cadence (every 9 days vs every 9 months). On price and ads there is nothing between them.
