How to make Special Scenes

I was wondering if someone could tell me online apps that they use to make special scenes because I would love to learn how to make some for myself and not give all the helpers such a hard time

Ibis Paint X is a good source

is it online?
Also I’m on computer

No it’s an app you can download on your phone

okay i’ll test it out

I use Medibang Paint Pro on my Laptop, it’s a software.

ok thx
