It’s all that I need

I Use it daily
This is the best basic calculator I have found. It functions well and it shows the progression of your work, almost like an old fashioned calculator with a paper readout would do. The buttons are a good size, so not too many “big finger” issues, and they’re sensitive enough to not miss numbers as I input them.

I downloaded this app years ago and it was my go to calculator. The other day I went to use it for a quick basic calculation and when I clicked the button the clear I got a pop up that this is a paid feature. The app now has several tiers of subscription and is basically unusable without a subscription. A subscription for a calculator...really? A paid calculator app-ok that I can understand but to pay a monthly fee. No thanks. I was particularly upset because I have been using this app for years. I hate when companies take an existing product and customer and try to force them into paying more for something that that the customer is already used to using. Believe I paid 99 cents when I first downloaded this app but I may be wrong. Go find another calc app that is free or simply a flat fee of $.99 or $4.99 there are literally hundreds of options. I deleted the app and for me went back to apples calc For the basic needs I have.

Wish you contacted us so we could remedy your particular case. The app is still usable for basic use if you tap and hold the delete/backspace button to clear instead of the AC button. We had to change our pricing structure in order to continue providing the same quality user services and experience going forward. Thank you for your past patronage!

A really well made Calculator app that replace the default calculator app on both my iPhone and iPad. Many convenient features, clean UI. Can’t recall any crash in the years I have been using it.
