App Detail

Ruler turns your device's screen into a ruler for measuring small everyday objects such as screws, coins, photos, cards, and pieces of cable. Place the object on or next to the screen and read its length in centimeters or inches.

MEASUREMENT MODES
• Ruler — place the object on the screen and drag the marker to measure its length.
• Two-Point — drag two markers to measure the distance between them anywhere on the scale.
• Rectangle — drag the corners to measure width and height together.
• Protractor — line up two arms with the edges of an object to measure an angle.
• Long Ruler — measure objects longer than your screen by sliding the device along them (Pro).

WHERE IT HELPS
• Checking the size of screws, bolts, nails, and beads.
• Measuring jewelry, keys, and small accessories.
• Checking photos, cards, paper, and small packages.
• Measuring the angle of a cut, a corner, or a bend.
• Measuring a shelf, a board, or a frame with Long Ruler (Pro).

FREE — INCLUDED FOR EVERYONE
• Ruler, Two-Point, Rectangle, and Protractor modes.
• Units: cm, inches with fractions down to 1/16, and decimal inches.
• Calibration for accurate measurements.
• Up to 3 saved measurements; restore, copy, or share them.
• Keep-screen-on option.
• Available in many languages.

PRO — ONE-TIME PAYMENT, NO SUBSCRIPTION
• Long Ruler mode.
• Measurement lock.
• Slow Scroll for fine adjustments.
• Measurements to two decimal places or 1/32-inch fractions.
• Unlimited saved measurements.
• Custom theme color and dark theme.

PRIVACY
• No ads, accounts, sign-up, or tracking.
• Measurements are stored on your device. The app does not send them to its own servers.
• If Android backup is enabled, measurements may be included in your device backup.

CALIBRATION
Devices do not always report their screen size exactly, so the scale may be slightly off at first. A quick calibration improves accuracy in the length-measurement modes.

ACCURACY AND LIMITS
This app is a practical aid, not a certified measuring instrument. Results depend on the device, the calibration, and how carefully the object is lined up with the scale. In Long Ruler mode, the device is moved several times, so small errors can add up over longer distances.

Do not rely on this app alone for professional work or safety-critical decisions. Use an appropriate measuring instrument when exact measurements matter.
