## What is kakdo°?

Opening angles and angles in photos.
kakdo° lets you check a compatible device’s opening angle as a number, and measure and record angles in photos.

■ See the opening angle
On compatible hardware, the angle follows the hinge as it opens and closes. Check the opening angle and its supplementary angle as numbers.

■ Measure photo angles
Measure an angle that catches your eye in a photo. Keep several angles on one image.

■ Keep your photo measurements
Add notes and save photo measurements on your device. Reopen and edit them later, or share a PNG image or CSV.

One purchase. No ads or subscriptions.

Photo features require iOS/iPadOS 26.5 or later. Separate Live hinge readings require compatible iPhone Duo hardware, iOS 27.1 or later, and available public-API data.
Photo measurements are 2D angles in the image plane. Viewing direction and point placement can make them differ from the real object’s angles.
