iPhone
The folding rule for your iPhone: ruler, protractor, level and diameter gauge. And on iPhone Duo, the hinge itself measures – to the degree, live as you fold.
Foldmeter turns your iPhone into a measuring tool – and your iPhone Duo into a folding rule: unfold it and the app shows its angle to the degree, live as you fold.
ON EVERY IPHONE
• Ruler: Centimeters or inches along both screen edges.
• Diameter: Lay a screw or drill bit on the screen, drag the lines to its edges, read the size – with a hint for the matching thread size (e.g. M6 or 1/4″).
• Protractor: Place an object on the screen, drag the arms to its edges, read the angle.
• Level: Upright for shelves and picture frames, flat as a bubble level for tables and surfaces.
ON IPHONE DUO
• Hinge angle: Your Duo's angle in large digits, with a side view of the device.
• Hold values: Keep up to three readings and compare them.
• Ruler and diameter on both the inner and the outer display.
PRIVACY
No ads, no tracking, no account. All readings stay on your device.
