Compatible with iOS 12.0.x and 12.4
MathTeacher is a brand new package that allows you fully customize your Calculator app and enhances it.
There are two new views that adds some additional functionality to the Calculator app: a new copy button that replaces the long tap gesture to copy the result and a label at the top that displays your current calculation.
You can access MathTeacher settings page within the Calculator app by tapping and holding the new copy button for a couple of seconds. Here you can easily change button colors, change calculator layout and other cool stuff. You can also quick toggle dark mode just by swiping with two fingers to the top or bottom anywhere.
KNOWN ISSUE: The history label can be buggy.
