Typically I use pen and paper, but I’ve been interested in a tablet or similar device for a while and am interested in what other people are using.
The reMarkable 2 seems like a really cool option to play with, but also pretty pricey for trying it out to see if it would even work well.
While it’s not directly related, when playing in games, I usually use a paper character sheet for reference, a notepad for consumables, story notes, and HP, and Pathbuilder on my phone for spells.
I’ve been using Foundry for our face to face games. One of the players logs in and casts their screen up onto a TV (which has a Chromecast plugged in). That person typically just moves the tokens for anyone who isn’t using a laptop. When we’re doing exploration, they just pile all the tokens into one space, so they can be moved as a group. Everyone does their character sheets on Pathbuilder, and the import to Foundry works fine most of the time. I don’t care if people roll their own dice or do it through Foundry, either way works fine.
We don’t tend to sit around the kitchen table anymore, so this is still less awkward than trying to get everyone to come look at a battle map on their turn when combat is going on. Setting up the tokens and maps ahead of time is much faster than hunting for miniatures and drawing maps on a wet erase battle mat, too.
