Carpenter Square is the best application for builders, contractors, and mathematicians alike. Instead of squaring your corners with decimals, Carpenter Square will auto convert and calculate from readable units like feet, inches and sixteenths.

Enter any 2 of the edges in your calculation, and the application will automatically calculate the 3rd. Or use ARKit and use your camera - just point and let the phone create measurements for you!

Perfect for quick calculations on-site without any extra conversion or hassle. Now, faster than ever, contractors and builders can take their calculations directly from the tape measure into our application, and immediately return to measurements in seconds. Additionally, users can now store their previous calculations for quick return to their measurements without typing in anything! We'll even show you diagrams of all your present and previous measurements. No sign up or account necessary. Just download and go!

The app had been designed an engineered for quick use in the field by contractors with more than 30 years in the building industry. Carpenter Square is guaranteed to satisfy your squaring needs better than any other application.
