Help/Support Need Advice How is IDA pro better than flex3

[DXcool223 11.5k iPhone 12 Pro Max 17.0]

So I believe I Have Mastered flex 3 and now I am trying to learn ida pro, I can jump to address from the binary in hex, and I have changed a bool value true and read many tutorials 

so I have been messing with it a little and I just can't see how this is any better than flex 3... but I heard it was, can I change values that I normal could not in flex 3?

Really I just want to block ads in apps and I normally just hack apps not games and there really are no tutorials on this

I have 2 questions 

1. How is IDA pro better than flex3

2. how can I get better at hacking apps in IDA after coming from flex 3,

Flex allows you to modify Objective-C/Swift methods, as it "dumps" those method. This is nice, especially for tweak development. However, if you take modern games as an example, flex will be useless 99% of the time. This is because game engines strip method names, also known as sub_x methods which you can not modify within flex as flex can not "dump" this.

In IDA, you're loading the game's executable, and have access to all of its code to be modified (note: most games have some server side code that you can not modify, hence why some games don't have things such as currency hacks as the server side validates this).

IDA is more complex than Flex, but with some tutorials you can find around here in the form you can quickly learn to mod games with IDA, especially Unity games as those games can be dumped with a tool called il2cppdumper. This does basically what flex does; It dumps all methods, classes, variables etc of the game and all you have to do is look up the address inside IDA and modify it.
