Is there a custom combo creator app for iOS?

so i know theres a few different good apps out there for different fighting games, but is there any good apps out there, whether specific to fighting games or in general, that you can use to keep track of combos?

ive been trying to search for something like this for a while now because i switch around to so many different games that ill forget combos that i practice or come up with (especially in tekken) and it would be nice if there was an app that i can just punch in arrows and different notations for different games…hell i would even do with just a standard reference guide maker and use text notations if i have to…i see a lot of apps out there that do things and are pretty simple, id think there would be a way to make those without actually having to code an app
