Best Calculator App Ever

I love this app for calculating all of the “maths” used in writing knitting pattern instructions for my design work! I’m so far on the right side of my brain that I can honestly say I can’t do long division on a piece of paper any more (pretty pathetic) and I can really confuse myself doing multiplications to determine the perfect shaping of the garment I’m designing for different sizes.
Simple and clear to use,doesn’t suddenly interject past calculations into the current actions, which makes me totally doubt my sanity! Thanks App Creators!

Incredibly Awesome

This Calculator App tops them all
It is the ultimate I have used since the advent of smart phones.
I downloaded the free version. On seeing the potentials, I immediately downloaded the paid version same day.
Worth every dime I paid.

Perfect calculator app

I was using the free version of this app for awhile before I finally got the paid version. Worth every cent not to have to deal with advertising. This is the best calculator app I've used, hands down.
