Great app

Just utilised this App' to find some angles on a motorcycle frame I'm currently modifying. Works perfectly and for FREE, you couldn't ask for more.

Looks great on my iPhone 4 too. Some apps I've paid for haven't even bothered to update a new hi-res icon.

Does not work

This app does not work unless you send a tip or purchase it, totally misleading when it says it’s free

Developer Response ,

You can use the right triangle calculator, and conversion charts without paying a thing. You only need to pay to use the oblique triangle and circle segment calculators.
