Rafter calculator

★★★★★ I believe dimension H on the input on the free version should show to the bottom of the rafter. If I enter for instance a 100 mm rise and a 100 mm rafter thickness it still gives me a rafter angle. Also, the birds mouth often gives me a height greater than the thickness of the rafter. A good little app if you know what you are doing but dislike math or just don't do it often enough to remember the formulae like me. Ads can be intrusive, but you have to pay your way somehow.

★★★★★ I spent hours trying to find an app that'd explain

★★★★★ Good app. Had no clew how to make a rafter. With this app and a framing square my shed roof is perfect.

★★★★★ Just downloaded this app because I was having trouble getting my angles on my cuts to line up for my shed roof im building. This app helped with all my measurements. It came out perfect.

★★☆☆☆ Needs way better instruction on use... Also, if I had all those numbers what do I need this app for

★★☆☆☆ I paid the two dollars, and it still has ads and doesn't offer inches

★★☆☆☆ It didn't calculate anything. It cleared all my data on several attempts and kept switching to metric.

★★☆☆☆ This app does nothing. It doesn't calculate anything. Absolutely useless!

★★☆☆☆ This app does not work. The measurements it gave were completely off, I had to just measure them by hand.
