Is it possible to move data to external SD

My android phone memory is limited but I have a very big external sd card. I moved the app to external SD but it is only 50MB but still about 600MB of data, for airports and planes, are still in main memory.
Can I move them to card, if not unfortunately I need to delete this app while I love it.

What kind of issues are you having? Lag?

It is not supported currently, sorry.
