iPhone Screenshots


Calipers lets you take measurements when you're on the go.

For the big things, there's 5 meter tape measure. Simply place your iPhone on a surface so the ‘zero’ aligns with where you want to start your measurement. Next, place a finger near the bottom of your iPhone and slide your iPhone along the surface, keeping your finger still. Finally, when your finger reaches the top, repeat the process again until you’ve completed your measurement

For the little things, the calipers mode will let you measure objects within a tenth of a millimeter. Simply place an object on the screen, and drag the top and bottom guides until they are just visible. To get really accurate readings, you can use the ‘plus’ and ‘minus’ buttons to move the guides closer or further apart by a 1/10th of a millimeter.

6 out of the top 10 free apps in this category are off by as much as 10% on the iPhone 12 & 13 Mini, or when some accessibility features are enabled. Since most people don't check their app against a ruler - we felt it was really important we did! This app has been throughly tested to ensure the measurements are accurate in every scenario.

What’s New

Version 1.4

Improves some animations and fixes formatting of markers placed before the ‘zero’

Free app that doesn’t take data

For a free app that does not collect any info, it is quite nice & useful. Can’t really complain about anything. (From Reddit)

Good in a pinch

Initially I was a little confused on how to use this but it works great after you figure out how to use this. The calipers are cool too
