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.
