The Math Keyboard

It doesn't work on iPad at all

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.”
