Angle Meter

An angle finder, bubble level and protractor in one app, made for woodworking, electrical work and DIY. Stand the phone on an edge or lay it on a board, and it shows the angle in degrees, or in percent, roof pitch or radians. Ask for readings by voice, and find a calculator, laser level, conduit bending and more in the side menu. MEASURE ANGLES • Edge: stand the phone on any edge to read its angle. Back: the slope under the phone. Level: both directions, like a bubble level. • A tap on the dial freezes the reading. • Degrees with your choice of decimals, or radians, percent, x/12 roof pitch, 1:n, mm/m or in/ft. • Ranges of 0–90°, 0–180° or 0–360°, the complement, the difference between two angles, angles from a reference, and your own zero mark. • More than 20 dial styles, five free, with Neon and Rosewood in Plus and the rest in Pro. HANDS-FREE (NEW) With voice commands (Pro), "hold", "save it" and "show degrees" work without a tap, and "read it" speaks the angle. Say "15 degrees" and Target lock (Plus) stops the meter when you've held that angle steady, with a beep, vibration or speech. Cues (Plus) beep, buzz or speak as the angle changes. On the free plan, all three can be tested before you upgrade. RECORD OVER TIME (PRO) Interval measurement logs readings at a pace you set, from ten per second to one every few minutes. See them on a chart with the average, minimum, maximum and spread, add a photo per reading, and share a spreadsheet or PDF. MORE ANGLE TOOLS • Rotation angle (new): fix the phone to a wrench, valve, wheel or door and see how far it turns, past full turns and either way. Set a target such as 90° and it beeps right there. • Corner angle finder (Pro): set the phone on each wall to get the corner angle and the miter for both sides. • Protractor: drag two arms over the camera view, follow the plumb line or type the angle, then keep a photo. • Laser Level: a level laser line across the camera view, with sighting and angles between points. CALCULATORS • Calculator (new): a scientific calculator in degrees, minutes and seconds that can use the phone's angle, a fractions calculator with steps, and triangle and percent calculators. Pro adds polygon, compound miter, bolt circle, threads, survey and more. • Electrical calculator (Pro): Ohm's law, power, cable and motor math, resistor color codes and wire colors. • Unit converter (Plus), with slope and angle taken from the phone. FOR THE TRADES • Conduit bending: lay your phone along the pipe and bend to the exact angle, with springback, offsets, saddles and 90s marked out. • Ruler: length, diameters, thread pitch and wrench sizes on the screen. • Tachometer: an RPM meter by sound, camera, vibration or spin. SENSORS AND DIRECTION • Sensor test (new): check that motion sensors, compass, barometer, GPS and microphone work, with a guided checkup. • Decibel meter (Pro): sound level with A, C and Z weighting, plus audio and video recording. • Lux meter (Pro): room light, plant light and photo exposure. • Compass with bezel and globe faces. KEEP YOUR WORK Records hold your readings with tags, photos, voice notes and reminders, and export Excel, CSV or PDF files. Charts plot them, the Gallery keeps every photo and video you take, and the To-do list holds your tasks with notes and reminders. PLANS The app is free and shows ads. A Plus or Pro plan, billed by the month or the year, removes them and opens extra tools and dial styles. Prefer one payment? The Pro edition sells as its own app with every feature. Every phone's sensors differ, so run a calibration on something flat for the best results. Questions or ideas: smarttoolfactory@icloud.com
