If your going to charge money

Just charge it. Without “pro” my phone has 90% of this stuff and that percent marker is proof

Don’t waste your time

Have to pay for the pro version in order to get basic symbols, which are already available on a normal keyboard, including the basic iPhone keyboard. Plenty of better apps out there, don’t waste your time or money for nothing!!!

It's sorta cool until you pay for the pro version. Until then relational operators and curly & square brackets among other symbols are blocked? SciKey gives all for free. Just sayin.
