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.
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.
This is what I've been looking for for months, expression editor with instant answer, simple UI, fast one, it also came with extra features like keyboard, widget, great settings, clipboard, and everything you need, I didn't even know how much this were important until I saw 'em here, BIG LOVE DEVELOPERS
