Customer Reviews

Very clever calculator features. Intuitive Interface.

This app is so convenient to use for all my calculating needs. The choices of calculators is just what I wanted. Occasionally, scientific features are necessary. Most of the time the standard features fit the bill. The app has performed without error and I do not leave home without it... It completes my iPad Mini 3. I recommend this app.

Very useful and handy!

Love this app for quick calculations! I use it for banking, for craft measurements, for all kinds of applications and having it right on my iPhone or iPad is so convenient! Thanks

It's a calculator. I paid for it.

It works. It adds, subtracts, multiplies.... I wish they would stop trying to sell me other apps. It runs slow. I wish they didn't try to sell me apps that I don't need or want. I paid for this so don't treat it like a freebie
