What sorts of tools/apps/programs/etc do people use to journal or record their solo adventures? I would love to have a fancy notebook and roll physical dice but being realistic I think something I could run on my Android as either a web or native app and handle both dice rolls and journaling would be ideal. I'm currently considering RoleGate since I use it for some PBP games with moderate success but I'd love to hear what other people use or have considered, either as all-in-one or standalone journals/dice/etc to make a complete system.
I use obsidian.md on the desktop and android for organising my campaigns, solo or otherwise! I like it because you control/keep the markdown files - they're not at the whim of a cloud-service that may disappear or jack up their prices. It supports add-ins, and I used the dice-roller one to make several oracle pages, for Mythic tables, and others. And of course to just roll dice. Obsidian is very cool, with many features!
@Gunderstank@doggoblingames I've heard that Obsidian is also an excellent choice for notes, yes. It is also used for Second Brain-type stuff just like Emacs which I use.
