Solo Roleplaying

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.
