Great tool for a sawyer. It is very handy to be able to give a board foot total in the log. Best for a small sawing job or hobby users, because it does not save the tally. It is probably wise to pay for the pro version. The log weight estimator is the cherry on the cake.
Awesome Freaking Cool app man exactly what I was looking for to use when buying logs for my sawmill. The free one works great but I needed to retain my tallys so I payed for it great apps does exactly what I needed to do. Highly recommended.
v3.1.0: add Scribner Table log rule, add Custom Species, change 7" tabs to default to 3 panes.
