Check out this handy link courtesy of the Obisidan discord. Syncing between devices can be somewhat cumbersome if you don't want to pay for Obsidian Sync, but a lot of people (myself included) have success with using FolderSync on android with whatever cloud service you have your notes on.

I pay for Obsidian Sync because I really like what the developers have built and want to support them.

It is extremely convenient. I mostly use my Rocketbook for drafting and brainstorming and then refine it by rewriting it into Obsidian.

I'd imagine the Android App and Sync would be sufficient since RocketBook supports OCR.

I sync my Obsidian vault with my Nextcloid using the app "FolderSync". In Rocketbook, I can set a folder in my vault (on the nextcloud) as destination for the export. Then it syncs to Obsidian on all my devices.

I use an iphone and ipad and have shortcuts that paste images of scans into my daily notes and other places. I actually use Scanner Pro app which produces a pretty good image. I use exercise books (A5-ish size) as I found the slighly smaller pages more useful. The ios shortcuts are super-simple to make.

I do have a Rocketbook and used to use it a few years ago when I had my notes stored in Evernote. Rocketbook is a great idea but I never got used to the plastic, textureless feel of the pages.

What I don’t do is any form of OCR on my handwritten notes though.

Not Rocketbook, but somewhat adjacent. When I want to handwrite, I use Nebo because it has remarkably good handwriting recognition and even allows for drawn markdown syntax. Then I just copy/pasta in Obsidian. Nebo is installed on my Galaxy Tab S7+. Not very elegant, but works well enough for when note taking on a laptop is disruptive vs using the S-pen and tablet combo.

TIL about Rocketbook, thanks!

When I'm on mobile, I'm capturing notes, images, links, and thoughts using the Android App and sync them through with Syncthing to my desktop and office laptop.
