It is missing helium.

I noticed that P for phosphorus is listed twice in the second main group and in the S shortcut group, but He isn’t listed at all.
Otherwise, I am pleased! :)

Not working in other apps

I bought this app to be able to write all the formulas in my chemistry notes but i have the settings turned on and i added it to my keyboards but for some reason im unable to use the keyboard in any app so i have to keep opening up the app and typing out what i need and then copy paste it into my notes :/

very good and some question

This chemistry keyboard app is user-friendly, but it’s missing key chemical symbols. I hope all standard chemical notations (like ↑, ↓, ) can be added in future updates. It would be much more useful then!

so useful for digital notes

i study biochemistry and this genuinely saves me so much time. i hate writing out equations manually or having to google sub and superscript to paste into my notes, this keyboard has changed the game for me!!! i love being able to do my notes on my ipad rather than laptop, not only is this saving time but also saving my shoulder from having to carry around a laptop all day!!

Response from developer

Thank you so much for the kind review. It made my day. ∞

Does not allow custom subscript or superscript lettering not preset

This app does not allow for superscript or subscript lettering that has not been predefined. Possibly useful for chemistry only representations.

Response from developer

It is limited to Unicode subscripts and superscript. If you can find one that is useful, I’d consider adding it. —glenn
