Price issue

This app was in AppsGoneFree on June 2, 2019. The download was free, and the upgrade was supposed to be free, but I got charged for the upgrade. Not crying over the $2.15, but still not happy about being charged for something that was supposed to be free.

Developer Response ,

The free app promotion ended this morning 5/3 EST. The advanced features (in-app offer) were not part of the promotion. You can always ask for refund on any charges on the AppStore using Apple’s official refund procedures :-)

Used to be good

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.

Developer Response ,

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!

Now a subscription app

This is a very good app and was my go to calculator. Now it’s a subscription app, but it’s cheap enough. However I hate subscriptions. So I ended up switching to their upfront single purchase price calculator to avoid going with a subscription. There are a lot of calculator apps out there but this one is one of the better ones. I do wish it had haptic feedback. I do love the widget that’s available. I do wish there was an option to shrink the equal button and put the division button in the same column as the other operators.

Developer Response ,

You can actually switch to haptics feedback if you tap and hold the Options button in the top left corner. We’ll look into providing options for the equal/division buttons 👍🏼

Old response:
The app still provides the basic calculations for free along with the widget among other things. Plus we provide number of options if 0.5 USD/year subscription is not something you’d be interested in.
