In order to get most of the utility out of the app, you need to make an in app purchase.

Amazing even the basic plan has plenty of utility and with the premium plan, of which I’m yet to purchase, you get access to tons of symbols, keyboard customisation, and the ability to add your own Unicode characters. If you’re even looking at this you should download it and consider the premium plan later on if you want it.

The only thing I would add is writing letters in lowercase and uppercase

Cara, por que eu pagaria 5,00 reais em uns símbolos que eu usaria de vez em quando? Sinceramente, as únicas coisas que adicionam no teclado de graça são o expoente e o número pi

Thank you! The super and subscript shortcuts are very nice. Many common symbols for mathematics are present. I would wish for more „hidden keys“ (e.g. ⇒ in the other direction).

I think there are way too many thing that need to be paid for, for example you have to pay a dollar just to change the color of the keyboard, and if you think about it if the developer keeps getting people to pay one dollar guess how much money they’ll have😡

It says you can unlock new layouts by paying(of course, who would’ve thought), but it doesn’t say you only get half α keyboard for installing. Rate it 5/10 because the normal version of the all gives you no symbols you can’t find on the regular keyboard.

Not sure if I’d buy this without seeing better samples of what it could do. Does this allow formulas? Not clear!
