It’s ok but could be so much better

The superscript and subscript numbers are helpful, no doubt, however I wish there was a way to expand the repertoire of superscript/subscript options. As other people has noted, this app lacks the superscript + and -, which would be useful in writing chemical equations and such. Furthermore, an entire subscript and superscript alphabet (or something of that nature) would be exceedingly helpful for writing equations, variables, fractions, etc.
Finally, while I do find the lack of many Greek letters such as μ to be odd for a scientific keyboard, I get around this by adding a Greek keyboard to my set of options. It is, however, rather cumbersome having to constantly switch between multiple keyboards just to write one equation.

Needs more symbols

This math symbols keyboard is the best of the various free ones I could find. Still, it's missing a lot of symbols that would be good to have. Most notably an arrow symbol --> for writing limits and functions is missing.

There are also some symbols in here that we DO NOT need. Particularly, much of the keyboard is devoted to Latin and Greek letters. However, not all the letters are included. For letters we can switch to the normal keyboard. And apple already has a Greek keyboard that works fine.

I would rather have one specialized keyboard for ONLY symbols that I could switch back and forth from. This is a clearer goal than trying to make a keyboard that you would never have to leave to type math (which may be overambitious?) By eliminating the letters you make space for more symbols.

That said, this flawed all is still the best free app on the App Store for its purpose. Thank you to the author, and please listen to the feedback!

Not a good keyboard

I needed a math keyboard for writing proofs. Unfortunately it is very inconsistent; There are 3 panels to choose from. Among them, one panel has an entire row dedicated to ordinary variables such as a b x y z etc. Why? The issue is that instead of wasting space with these letters (as iPhones already have letters like this) why not add more symbols? This keyboard includes the conjunction symbol, but not disjunction? Quantifiers? Implication? set notation? These symbols could’ve easily been added instead of letters like a b d i j ... Instead we see clear poor design choices. This is the best math keyboard and that says a lot. Unfortunately it isn’t practical. For lower level math this is sufficient; for higher level, don’t waste your time.
