How to connect Webflow website to mobile app?

Hey guys!

I need to know if it is possible to connect the Webflow website to custom-made mobile app.

More info:
My client wants a new website built in Webflow and needs the option to sign up for an account. The problem is, he wants to sync data with the mobile app.

Use case:
The user creates an account on the website. After creating the account on the website, he downloads the mobile app and just logs in to the mobile app. It looks like the website and mobile app should be connected to one database…

The question is… Is this doable in Webflow? If so, how is it doable?

Thank you!
