Custom List Via External App

Hi all,

Appologies if this has been asked before, I've tried searching but couldn't find anything.

I'm looking for the best way to add films of interest to a list via an android app, that will then appear on stremio ready for me to watch.

For example, if someone tells me about a film, I'll add it to the list on my phone ready to watch later.

Does anyone have any suggestions please?

I currently use aiolists and mdblists if I can someone incorporate these.

Many thanks.
