Rafter Tools

Rafter Tools is an android app with functions to calculate complex roof framing angles that other roof framing calculators can't and don't offer. Calculating common rafters with a construction calculator is fairly easy, but to be a master carpenter you need more roof framing angle information then the construction calculators offers. With the Rafter Tools android app you'll be able to calculate all of the complex angles for roof framing. The app's main screen uses a left swipe motion to display all of the different calculators.
