Angle Meter

Acerca de Angle Meter

Angle Meter turns your phone into a precision measurement tool. Whether you are checking if a shelf is perfectly level, measuring the slope of a wheelchair ramp, aligning a solar panel, or setting a saw blade to an exact bevel angle, this app gives you accurate, real-time readings straight from the sensors already built into your device. No extra hardware, no setup wizard, no account to create — just open the app and start measuring.KEY FEATURES• Real-time inclinometer — see pitch and roll values update continuously as you tilt your device in any direction• Full protractor overlay — drag the needle to set or read any angle from 0 to 360 degrees with a clean visual display• Angle lock — freeze the current reading so you can hold the device against a surface without watching the screen• Save measurements — log any angle with a single tap and build a persistent list of recorded values you can review later• Calibration — set any physical position as your personal zero reference point for relative or offset measurements• Dual display mode — view inclination as degrees or as a percentage gradient, whichever suits your workflow• Large, high-contrast readout — digits are easy to read in direct sunlight, on a dusty job site, and in low indoor light• Portrait and landscape support — use the app comfortably in whichever orientation makes sense for what you are measuring• Works fully offline — no internet connection needed at any point; the app never phones home• Lightweight — minimal drain on battery and negligible use of storage spaceHOW IT WORKSAngle Meter reads data from your device's built-in accelerometer. The sensor detects how your phone is oriented relative to the pull of gravity, and the app translates that into a precise angle value displayed on screen. The reading updates many times per second, so you can move slowly along a surface and watch the value change in real time, stopping when you reach the angle you want.For the protractor, you drag an on-screen arm to align it with a physical edge or surface, letting you measure angles visually without needing a separate protractor or combination square. This is especially useful when you want to match an existing angle from one object and transfer it to another.The lock feature captures the live reading at any moment and holds it steady on screen. You can then step back, compare surfaces, make marks, or take notes without the number shifting. When you are done, unlock and the live feed resumes instantly.Saved measurements are stored locally on your device and remain available between sessions. There is no export or sharing function — the list is a simple personal reference you can scroll through and clear at any time.WHO IS THIS FORAngle Meter is useful for anyone who needs to measure tilt, slope, or inclination without carrying a spirit level, protractor, or other specialist equipment. Tradespeople and serious DIY enthusiasts reach for it to hang pictures perfectly straight, set door frames plumb, check concrete pours, verify that installed fixtures sit at the correct angle, and align shelving brackets. Cyclists and vehicle owners use it to measure fork rake, check suspension geometry, or confirm a trailer hitch drop angle. Students and hobbyists use the protractor for geometry work and craft projects where angles matter. Outdoor users apply it to measure trail gradients, set up equipment on uneven ground, or position a solar panel for better sun exposure.If you have ever needed to know quickly and reliably how far off level something is, this app gives you that answer in seconds — without reaching for a bag of tools.No subscriptions.
