Pouchdb

Should I use Pouchdb or Firebase?

I want to store text documents and notes. Most of them are very short, just a means of tracking information while I'm doing research.

I want to be able to access them from multiple locations, preferably through a web browser but that is not a necessity.

I've also considered putting my information in a text document or word document but I would like to be a little more formal about the process.

What databases do note applications use to keep their users' notes synced across devices? The only option I keep bumping into is Pouchdb/CouchDB, but that takes me out of the AWS stack and introduces other issues and more costs.

With so many note-taking apps out there, I thought there must be a solution or a template stack. Most resources are either for a chat app with WebSockets or for toy apps without cross-device sync.

We are building an offline-first Android SDK app. The solution we're working on runs on a mobile device in areas where internet connectivity is intermittent or does not exist. The applications needs to be able to collect data and when it reaches a home base or finds internet connectivity, we'll sync it with the host.

We've heard Realm and Pouchdb could be a good solution, but we are curious if anyone has any experience with either or have another path forward.
