What is the ⚡️FASTEST⚡️ way of building a "nocode" desktop and mobile app?

Requirements:

1) it needs user registration
2) it needs to match users based on location
3) there is no three, that's all

Some more specifics: it only has to hold a handful of users, say 1000 AT MOST (but probably much less); "some" coding is fine, I have extensive JavaScript knowledge and integrating a couple of APIs could be OK as well, as long as they are near-zero configuration.

probably figma?

That would be for designing, but I'm looking for technologies to build the app.

How is JavaScript nocode?
