SciKey - Scientific Keyboard

As title, any way of getting superscript + and - please.

Does not work at all

I Use this app all the time on my iPad pro for school work, especially Biology and Chemistry. It makes it so much easier to write notes and makes them look so much better. For example instead of 2^ to show squared, I can simply write ². It has an obscene amount of charaters, I doubt anyone knows what they all mean, but you can customise 3 seperate keyboards to have any of the characters, anywhere you want them. The ones I use most are subscripts for chemistry, for example: Cl₂, forward reaction sign →, reversible reaction sign ⇌, superscript ⁺, ⁻, therefore symbol∴, proportional to symbol ∝ and sum of symbol Σ. Can I make a suggestion to app developers though? Chemists like me would find it very useful to have subscript letters to show things like aqueous (AQ), solid (S), or liquid (L)

Great for school

:(

This is great and gives three keyboards of customisable symbols. My only gripe is that I’d like to be able to add another keyboard as I can’t fit on all the symbols I use onto 3.

Its a helpful keyboard for someone studying finance. Only annoying thing is the keyboard doesn’t appear while Ipad Pro keyboard is set up :(

This is a great free app. I have installed this and had a play. So far it has every thing I need in it. Thank you

I like how customisable it is, but I for me it would be more useful if you had the option of adding more rows of keys of the keyboard since for iPads (especially iPad pros) the keyboard looks quite sparse.

Not very useful on iPad Pro with external keyboard attached. Unlike emoji keyboard, this keyboard will not display while the external keyboard is attached. You see it for a second then it disappears.
