How to make changes to sqlite database for app that is installed in multiple devices?

I started developing an app that uses sqlite that is to be installed on multiple devices and any updates done on sqlite database from any device are to be reflected in other devices as well. I have researched a little and found that Sqlite DB is local to a device and changes done in one device are not reflected in others and for that I have to use external server. Is there any way around it? Is it optimal to directly store data in external server or use sqlite and sync it regularly with external database? Thanks in advance
