TouchRuler 4+

Meet TouchRuler! The most accurate digital ruler for your Mac's display, Notification Center, and Touch Bar!

TouchRuler comes with an on-screen 20 centimetre ruler, and a 12 centimetre ruler for your MacBook Pro's Touch Bar. Plus, with TouchRuler mini, you can add your ruler to your Notification Center, allowing you to drag it out to your desktop or full-screen app at any time to measure on the fly.

Just like a real ruler, TouchRuler shows the centimetre values beneath the tick marks in large text, allowing you to make a measurement at a glance. You can also use the Click Pad to grab an exact measurement and copy it to your clipboard in a flash, with a simple click on the ruler.

TouchRuler is great for designers, architects, students, scientists, mathematicians, and the rest of us who just need a ruler available to access wherever we are.

TouchRuler automatically calibrates based on your display's information, so you don't have to deal with an annoying first-time set-up. You can also manually adjust it with pin-point calibration tools later.

TouchRuler and TouchRuler mini come with four themes; Minimalistic, Classic, Warm, & Cool. In addition, you can also make the ruler transparent or float above all other windows to easily measure on-screen elements.

TouchRuler operates fully without an internet connection, has zero ads or in-app purchases, and does not require any user information.
