EASYRULER · EVERYDAY MEASURING
How wide is that paper cutout? What angle do those two edges make? Open a quiet screen ruler and give everyday measurements a clear place to start.
iPhone & iPad · iOS 16 / iPadOS 16 or later
A ruler. And a protractor.
TWO WAYS TO MEASURE
Align a small object with the scale at the screen edge. Move the orange and blue cursors to read the distance between two points.
Drag edges A and B independently, move the vertex, or turn the graduated ring to rotate both edges together.
INSIDE EASYRULER
Length, smaller angles, reflex angles and angle entry each have a clear place. Open any image to see the complete screen.
Read millimeters and inches between the orange and blue markers.
Position the vertex, each edge, and the graduated ring.
Keep the same edges and switch to the 300° reflex angle.
Use direct entry or common presets such as 30°, 45° and 90°.
Real app screens with example measurements and unchanged readings. See the App Store listing for device compatibility and the current version.
A USEFUL TOOL, WITH CLEAR LIMITS
Length conversion depends on your device’s screen information. Check against a reliable physical ruler on first use, after a device change, or whenever the scales disagree. Angle measurements do not need length calibration.
How to calibrateAlign a small flat object with the visible edges, or use the protractor as an on-screen angle reference. The screen cannot reveal a drawing underneath. Alignment and viewing angle both affect the result.

No ads crowding the scale. No subscription interrupting a measurement. The ruler, protractor and calibration work on your device, without an account.
Apple handles purchase and download through the App Store. See the listing for the price, current version and device compatibility. Opening support email or the privacy page uses the external service you choose.
PrivacyCheck the length scale against a reliable physical ruler, especially on first use, on a new device, or when the app recommends calibration. If the scales disagree, calibrate until they match. The protractor measures the angle between two edges and does not need length calibration.
No. iPhone and iPad screens are opaque, so you cannot see lines underneath. Use the protractor as an on-screen angle reference, or align a small flat object with the visible measuring edges.
No. They are adjustment steps for the cursors and measuring edges. Screen information, length calibration, manual alignment and viewing angle all affect the result. Check with a suitable physical measuring tool when strict accuracy is required.
The same two edges make two angles. The smaller angle ranges from 0° to 180°; the reflex angle ranges from 180° to 360°. A 60° smaller angle, for example, has a 300° reflex angle. Switch the protractor’s angle mode to read either side.
It does not save a measurement history or send measurements to us. Calibration and preferences stay on your device. Switching between Length and Angle during the same app session keeps each measurement available.
EasyRuler is a one-time App Store purchase, without subscriptions, ads or accounts. It supports iPhone with iOS 16 or later and iPad with iPadOS 16 or later. Length measurements are designed for the built-in screen; external displays are not supported.
