Prototyping mobile apps faster with a 208-screen UI kit

Why we built a modular design system instead of redesigning the same buttons for every South Florida startup.

The bottleneck

When building mobile apps for local startups, the design phase is always where weeks disappear. Agencies reinvent the same buttons, navigation bars, and list views for every client. That drives cost up and shipping speed down.

The kit

To fix it I built the TGA Mobile UI Kit, a reusable React prototype vocabulary organized around six product verticals: education, navigation, news and media, productivity, shopping, and social.

It is not a handful of screens. It is a system that generates more than 200 distinct layouts.

  1. Strict tokens: mint for primary actions, electric violet for accents, vibrant pink for anything critical.
  2. Current React: built on React 19 and Vite so prototypes compile and load instantly.
  3. Modular components: interactive suite components per vertical, restyled through data-theme attributes rather than rebuilt.

Stop designing, start shipping

If you are getting a product off the ground, stop paying to have standard UI elements designed from scratch. Use a system rigid enough that nobody can wander off it, and spend the time on your actual business logic.
