Introducing TouchRuler, a feature-filled, accurate ruler for your display, & Touch Bar.

TouchRuler comes with an on-screen 20 centimetre ruler, and a 12 centimetre ruler for your MacBook Pro's Touch Bar.

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 adjust it manually later.

You can customise your on-screen ruler with any of four themes; Minimalistic, Classic, Warm, & Cool. You can also make the ruler transparent to easily measure on-screen elements, and also calibrate the ruler in rare circumstances where TouchRuler may not be automatically accurate.

TouchRuler operates fully without an internet connection and does not mine user information.
