What’s New in Mathintosh 1.5: • Made for iPhone Duo. Mathintosh adapts to every pose: closed, open, half-open with the display above the fold and the keys below, or turned sideways with your paper tape alongside. • One clean toolbar. Paper Tape, Tools and Settings sit in the same place in every mode. • Crisper light themes. Bars, the clock and every mode are now easy to read. • Better layouts everywhere. Displays and keypads make better use of your screen, with bigger keys and a consistent look on iPad. • Fraction mode, upgraded. It fits on screen without scrolling, with a new compact keypad in landscape. • A redesigned paper tape. Clearer entries, easier sharing, and colors that match your theme. Plus a more readable clock on Apple Watch light themes, and many smaller fixes.
