Measure from any point with a movable zero, A–B markers and fractional-inch precision—then keep going beyond one screen.

Infinite Ruler

The perfect app for when you've forgotten your tape measurer in the shed and want to know how tall your coffee mug is. Or maybe you need to settle an argument about how big your cat's head is.

Measure in centimeters or fractional inches, then keep going beyond the length of one screen.

• Choose 1/8, 1/16 or 1/32-inch precision • Move the zero point to start anywhere • Place A and B markers for a live distance • Continue measuring across as many ruler pages as you need • Put the scale on the left or right edge • Calibrate per phone for better real-world accuracy

Your measurements and calibration values stay on your device.
