Was hoping it wasn’t so clunky

It’s a decent app, but not sure if I can say it’s worth just typing out LaTeX.

For some reason, trying to type a capital L doesn’t work. It just leaves a “box” where a character should be. A little infuriating when trying to consistently write, say, the definition of the limit.

There needs to be some sort of instructions as to what the paste button does. I’m not really sure what the difference is between the 2nd and 3rd buttons from the left.

That said, it’s probably worth $2 if you are typing advanced math on your phone A LOT.

Issues with ios18

Hello there, very recently bought this, as it seemed to be the most flexible scientific keyboard (allowing for tex file generation as well) - it does not currently work on ios18/18.01 - could the developer please address the issue? Will change rating if the issues are addressed.
Thanks

Error with Integral

I get an Error with typing integrals o iPadOS 17.5, the upper limit position of the integral shows in the middle and not at the top. In addition Summation Sign is only addable with top and bottom value, just the summation Symbol by itself would be nice. If fixed this app could be very nice and i would be willing to give full stars.

Not working

I activated the keyboard but if i want to engage it, it just flips to the default IOS keyboard. Not working at all. Lost money. Stay away.

Buy with caution

The app does not work on my iPhone. It does work on my iPad. I emailed the developer but got no response.
