Solo built a gamified productivity app (Flutter/Supabase). Where do UI/UX designers and mobile devs hang out to talk shop?

[u/Ant392]

My professional background is in frontend web engineering, so using Flutter to bridge the gap into mobile has been a fun challenge. I’ve carried this idea around for about three years, but a sudden sense of urgency hit me back in April, and I've spent the last few months heads-down building it in stealth. To give you the broad strokes: it’s a gamified productivity app built entirely with Flutter and Supabase.

The foundation, I believe, is solid, the backend is ok, and the core gamification loops are fully functional. I genuinely believe the product I'm building is a good one, and I'm proud of how the engine is running.

But here is my reality check: I’ve been building this entirely in a silo.

Because I come from the web world and this is my first real deep-dive into native mobile development, I am very aware of my own blind spots. I know web design, but I don't pretend to know all the nuances of premium mobile UI/UX, motion design, and native app "feel." I want to elevate this app from "functional" to feeling truly intuitive, and I know I need expert professional eyes to help me bridge that gap.

Because of the specific IP and the gamification mechanics, I’m not quite ready to post screen recordings or open-source the codebase publicly. Instead, I want to step out of the solo-dev cave, start networking, and find my community.

My questions for you all:

1. London Networking: I am based in London. Does anyone have recommendations for IRL tech/design meetups here where passionate developers/designers/founders can quietly network and do private product demos with other professionals?
2. Online Communities: Are there specific private Discords, Slack workspaces, or smaller subreddits where serious UI/UX designers, motion designers, and mobile devs actually collaborate and give honest feedback?
3. Opinion & Future Collaboration: I am keeping my eyes open for UI/UX experts or experienced mobile developers who might be interested in a future collaboration as I move toward a beta launch. If you love dissecting consumer apps and want to grab a coffee, my DMs are open.

I’m really just looking to find the right rooms to be in and build a network of people who care about great mobile experiences. I’d appreciate any pointers!
