Great Keyboard- With Add-On


This keyboard is pretty good in the free version. Has a lot of the standard keys and the interface is easy enough. But it really shines when you get the full set of symbols for 99¢. It has everything one needs for any math or physics writing. The thing I could most see making this better would be the ability to add multiple symbols to each key like the standard keyboard (ex: holding $ lets you access ₽¥€¢£₩). Not sure why the app needs full access for customization, but I'm not typing anything sensitive with it so I don't mind.

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!

Lots of options but needs some more


I got this app so I could write out chemical equations and calculus problems to my lab partner, so I wanted an integrated keyboard for texting. The superscript and subscript options are very helpful but I need a superscript plus sign (+) to be able to write the charges on cations, etc. I would also like to be able to turn off the keyboard sounds for the SciKey keyboard because they're very annoying if you're used to keyboard sounds being off.
