SmartAngle is a small (67mm x 41mm x 17mm) and light (30g) Bluetooth level which connects to your smart phone via an app. SmartAngle provides an extra hand when levelling - the angle is displayed on your smart phone, where you can see it, while you focus on the job, not on holding the level. The app requires the SmartAngle Bluetooth level which is available from Wordcraft International - www.wordcraft.com. SmartAngle's technical features include: Remote angle measurement for Apple iOS phones/tablets. Bluetooth (BLE 4.0) compatible. Size: 67mm x 41mm x 17mm. Weight: 30g. Power source: CR2032 battery - up to 2 year life on standby. Single membrane switch to wake SmartAngle from deep sleep. Power saving functions: user defined auto-timeout period - default 5 minutes. Auto turn off when app loses focus or is ended. Two LEDs used to indicate power on (unconnected), Bluetooth connected and approaching required stop. Unlimited digital stops: set the angles and the SmartAngle app tells you when you are there. An initial set of stops is provided: 0, 22.5, 30, 45, 60, 67.5, 90 - and 75.96 (4:1 ratio for safe ladder angle.) Audible and visual warnings when the correct angle is reached - no need to look at the level - just wait for the "beep". The tones used for warnings are adjustable - ideal for those who are losing their high frequency hearing. Voice message to read out angles This feature may be turned on or off with one tap on the screen. User-defined "voice stability time" - a reading must be stable for this time before the angle is read out. Default: 3 seconds. Angles displayed in degrees, percentages (14.26%), ratios/falls/slopes (1:7), mm/m or in/ft. Tap the screen to change from one to another. Selectable resolution. E.g. for degrees: 1, 1.5, 1.1. Measures the difference between slopes - measure slope 1, zero, measure slope 2, SmartAngle shows the angle between them. Temporary zeroing function for measuring relative angles. Step-by-step calibration instructions and diagrams shown on screen. Two rare earth magnets (internal) hold the long side to metal surfaces. Background colour selection - either as a solid colour or as a radial gradient.

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. 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 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: a full-height, calibrated on-screen ruler in metric or imperial units, with a drag handle that stays clear of the controls. • 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. Exports contain simplified geometry, not a photographic scan. • 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.

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 and no in-app ads. 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/

Verdict
The clearest difference is in-app purchases: SmartAngle at none against Digital Protractor & Level's 1. SmartAngle also leads on device support (3 vs 1) and iOS requirement (8.0 vs 17.0). On price and ads there is nothing between them.
