Fantastic. I rarely give 5 stars. Only possible improvement I can think of would be a larger text option. old dirty, calloused hands need space for tapping on stuff.

This seems like a good thing. I just went straight for the paid version. Looks useful. This is the first time I've seen a refund option Wich I think it's quite honest and increases my trust level with this app and developer.

First app I've paid for. I do a lot of woodworking and this is very handy. Any chance you can add a feature in calculators to get volume of a cylinder and cone. That is useful in calculating board feet of a log. 1 board foot is 12 x 12 x 1
