Much better than the 12c

Fast, great to use and reliable. Replaced my 20 year old 12c calc with this app a few years ago and never looked back

iPad Keyboard Fix

With the keyboard fix I now have a 4-star app that I can use both on the iPhone and iPad. Outstanding!

It upsets me.

A single, brief glance at the version history of this “once great” 12-C emulator tells a story of intrigue (essentially no updates since 2014). Come on. What happened to valuing loyal and appreciative customers? From your own description of this product, there seemed to have been no small amount of passion you poured into this calculator when you actually introduced fun to Finance. You’ve lost that loving feeling. Get it back, please?
