Interested in tabletop RPG games

Hi everyone! This is actually a couple questions, but hopefully you guys will be interested?

First off, I was wondering what iPhone apps are there to help play RPG games? I have already gotten ready to roll as my dice set. But as for character sheets I’m not quite sure where to start. I don’t know if there is a better app for it? Or if it’s just easier to write it down in something like Google documents. And what’s the best way to get rules/handbooks for different games? I can’t use a computer so I’m trying to figure it out on my phone. If there are any free samples that I could try to look at that would be wonderful!
Also, once I start feeling more comfortable with these types of games, I was wondering what kind of tips are there for trying to run a session? There might be a few people at camp who would be interested in learning but that’s kind of complicating things a bit.

Lastly, I was wondering if anyone on here plays RPG‘s? I’ve joined a couple discord channels and I’ve already played my first in person session! But I wanted to see if anyone on here would be interested in playing with me. I’m still really really really new to the whole game thing So I still don’t really know what I’m doing, anyone with experience would be a great help! Nothing too complicated, but I’m always up for an exciting and stressful story! My first game was actually call of Cthulhu… And surprisingly only one of us died LOL

Anyways, thank you for listening to my ramblings. Let me know if you know something, and have a wonderful Day/night
