Hi. I want to use adobe animate at home, but it's hard with a mouse, and I can't afford a drawing tablet. I currently have an iPad Pro and I've seen app suggestions that help use iPad as a drawing tablet for animate, but they all need subscriptions and I can't afford those either. I do have some USB type stuff so I can plug my iPad into the PC, but I don't know where to go from there. Are there any free alternatives I can use?
