The Math Keyboard

I wrote the following review 6 years ago when the app was a welcomed addition to my workflow. Unfortunately, the app has become more buggy in that time and has not been updated in 4 years. I think we can assume the developers have abandoned the app. “Great keyboard for math and physics teachers and students. I have noticed a less than optimal behavior with respect to superscripts and subscripts. Not all symbols render. For example, I can display U₁ but not Ug. The number 1 displays as a true subscript. But the g is a regular lower case g. Perhaps the developers reasoned that a regular lower case g looks close enough to a subscript g. But as a physics instructor, this is less than optimal. It would be great if the developers would look at this and consider expanding the subscript functionality.”

I like this keyboard a lot. It has most of the symbols I need. Some symbols I wish could be extracted. For example, inverse trig functions is just the letters and a superscript -1 exponent, so superscript could just be one symbol. Other square roots would be nice. Also, the alpha symbol is super small. Can that be fixed? It’s not legible due to it’s size. Lastly, can you add a favorites section? It would make using the keyboard easier. Thanks for the app.

I tried this app because I wanted one that worked well with the iPad, and it does. However, there is no integration symbol, and d/dx I can just type manually, so why is that even there? Even the free iPhone math keyboard app has this symbol. Not worth paying for, in my opinion.
