Kindly update, widget is not working on iOS 18

Developer Response
Apple removed all the old style widgets in iOS 18.We tried last year to build a new style widget, and it didn't work well enough for a properly interactive widget. It was quite slow to enter numbers, and if you typed too fast, the system would open up the main app because of bugs in the widget support. It's still something we would like to do, but it's not going to be anywhere as good as the existing widget.We will do what we can!

Widget STILL doesn't work on iOS 26

Just noticed that the Dev has replied to my previous review. Thanks Apple for not sending me a notification! I’ve noticed the same issue with many other calculator widgets in that the numbers need to be typed really slow, else a number or two could be skipped. It’s really annoying! I’d happily make a one time payment if I can just get a working widget like it was before. ————————————————The widget worked perfectly until the iOS 18 update. Now it wouldn't come up to choose in the widgets section. Without the widget, I have no use for this app as the native iPhone calculator app works just fine. Hope the developers will update it for iOS 18.

Amazing calculator

It’s just a calculator that calculates with no ads for free. Good product. What would be really cool was if instead of the icon saying 42 at all times that number was the result of the most recent calculation.

At the base minimum the app should offer localization which it sadly did not. While i still use it, it's not my calculator of choice. Please add localization support.
