About this gig

The most expensive mistake in app development is building the wrong screens beautifully.


We design mobile app interfaces and experiences for founders, product teams and funded startups delivered as an interactive Figma prototype your developers and investors can actually use.


WHAT MAKES THIS DIFFERENT

We design the flow before the pixels. Every project starts with the core user journeys, mapped and agreed, so the interface solves a real path through your product. You approve the structure before we design a single screen.


WHAT YOU RECEIVE

- Complete iOS and Android-ready UI, designed for real devices

- Interactive clickable prototype, testable on your phone

- Full design system: components, typography, colour, spacing, states

- Empty, loading and error states the screens most designers skip

- Developer handoff with specs, assets and exports

- Editable Figma source file and full commercial rights


WHO WE WORK WITH

Founders validating a product, teams preparing for development, and companies raising capital who need something investors can hold.


Fixed scope. Fixed timeline. Direct communication with your designer.
