SQLite offline first sync options?

I'm confused, and my AI chat buddies seem to be too. I have an iOS React Native app that stores data in a sqlite db. What are the best options these days for getting that data synced to the cloud and back?

My goals:

- offer this local data as something users can maybe alter and use from a web app or another device. There won't be a lot of frequent real time merging and syncing going on. I imagine it's going to be an infrequent sync operation. - I'd rather not rewrite everything to use a different datastore. - I see there are sqlite merging and hosting options (fly.io and litesync.io) but I'm not quickly groking if they are what I want here.

Really curious what you all are doing with projects similar to this.
