I loaded this app today onto my iPhone 13Pro Max, and I then double checked the software ruler on my iPhone against a physical ruler. I am happy to report that the software ruler in this app is 100% accurate. This is true for both the inch scale as well as the cm scale. Both are perfect. ## Frequently asked questions about Ruler Pro ### How precise is Ruler Pro? Ruler Pro is designed to be 100% precise by automatically adapting to your device's size and resolution.
