The App Store and Bubble

This needs to be addressed very quickly to new Bubble users. Bubble isn’t meant for building mobile apps. It is mainly a platform to build webapps, so creating an app will not be as easy as you think. Many users have successfully linked their apps to Dropsource via API, and I successfully used Thunkable to create an app to publish on Google Play. There are also a lot of forum threads about it:

And you can check out webview wrappers like Webview Gold or SuperView.

The only example of a successfully published app (to iOS and Google Play Store) is Yumbook.

Hope this helps!
