- Fix bugs on iPhone X and iOS 13
Ratings and Reviews
Working with ios 13 after latest app update!
My favorite calculator for iPhone stopped working after I upgraded to iOS 13 BUT the developer fixed that problem. The app is once again working like it should.
Developer Response ,
We are so sorry for the problem you have. Hicalc has been updated to be compatible with iOS 13. Please go to the app and take a look. Please share your experience with us by rating and reviewing Hicalc. Thank you so much.
Not supported anymore and several bugs introduced.
I have been using this app for the longest due to its many features but since the last update there are a couple of significant bugs (can’t change the tax rate in the top calculator and the calculator doesn’t fit on the screen when doing time/date add and subtract operations). The support page on the web doesn’t send the form and the Feedback section in the app doesn’t allow to send emails.
This is a gem of an app. I use the conversion part of it frequently and it covers almost any kind of conversion you can think of. I got it for the calculator that shows the tape of your entries and still like that feature.
