Bf wrong?

Pretty sure the bf calculator for lumber is wrong. In which case this app is useless cuz if that's not right how can anything else b trusted.

Very Good But

The fonts need to be larger to make the numbers easier to see. Color and contrast is good but lacking in the totals section making the numbers a little bit difficult to read especially in the bright sunshine. A running total would be very handy so you don't have to switch back-and-forth to the Kalkulator application. More species would be good also. There's plenty of room on the screen of an iPhone for larger numbers.

Doesn’t work.

I own a sawmill business. I downloaded this app because I was sick of always going to the web to pull up a website to do log volume calculations. This app does not calculate the board feet from logs accurately. It’s wrong every time, which makes it useless. I hope Norwood puts more thought into their mills than they did into this app. I bought another app that appears to have been written by an individual and it works great. Not sure why a company like Norwood couldn’t get it right.
