I would like to use my laptop for note taking in class, and use an android based e-ink tablet for handwriting and diagrams. What are your recommendations for delivering the tablet’s notes to the vault? Obsidian on the tablet with first party sync looks like a possibility. What about another app that can use SyncThing or similar that the laptop vault can turn pull?
I use Dropbox to sync between my tablet, phone, and laptop. Dropbox let’s you use three devices for free so I don’t pay anything for this solution and everything is backed up to Dropbox. My phone and tablet are both android devices so I use dropsync to actually do the syncing with Dropbox so that they can be accessed via Obsidian.
