Needs work. I found error. Wrong answer for sides a & b when givens of 14 side c and angle A of 22.5° This error can cost $ thousands of dollars in any machine shop!
★☆☆☆☆ Jordan Kallinen · May 1, 2020
Low accuracy, it rounded my inputs in some weird ways too.
★☆☆☆☆ Adrian3ngblom · Sep 14, 2020
Keeps crashing when I press solve. Edit. It does work if I set my phone to English (UK) instead of Swedish. Hope it helps.
★★☆☆☆ Ken Krozel · Oct 2, 2019
OK app-ads in free are unreasonably long for the little number of calculations performed. Uninstalling and will use Excel or google sheets.
