I'm not sure if I have fully gotten it correctly. It's a distributed database that syncs without conflict. So, cool for collaboration tools. What other things would you do with it?
Yes, it excels at synchronization, you could just put a server synchronized and you have your backup, or let each user of an application have his own server which is synchronized with others (e.g., for a smart lock system). That's something pretty useful for privacy or if you have connectivity problems like in a mesh network with interruptions.
For the app itself, its really about getting end-to-end encryption be able to use the app while offline without loosing data.
