User friendly

I have not used all of the various calculation functions but the ones I have used are easy to understand and therefore user friendly.

This is pretty handy!

Bravo! I wish I searched for this app sooner. I used to just search Google for these calculators and now I have it in a flash. Worth the $7.99 I paid for lifetime use.

Feature Update Request:
Be able to have multiple pie calculations that I can save, title, label, view, edit and maybe compare. Maybe scroll or swipe to access saved pies. Pies inside pies would be really helpful too.

Thanks for everything this is a great app!!!
