Vouxa

Vouxa is a rewards app I designed as client work: it connects to a user's email inbox to detect purchases automatically and turns them into cashback-style rewards, no manual receipt scanning or card-linking required. I designed the whole product end to end, shipping 6 distinct visual themes in under 30 days. This project stays under NDA, so the client, the real product name, and the company behind it aren't named here — everything below is about the product and the design work, not who it was for.

Most rewards and cashback apps ask people to manually scan receipts or link a card, and that friction is exactly where most users give up after the first try. The client wanted something that worked passively instead: connect once, and rewards show up on their own as purchases come in by email. That meant designing an onboarding flow trustworthy enough that a stranger would grant a brand-new app access to their inbox, and a rewards experience compelling enough to make that trust worth it.

• Getting a first-time user comfortable granting email access to a brand-new app, without the permission request feeling invasive or like a dark pattern.

• Designing an AI-assisted search for rewards and offers that actually helped people find something relevant, instead of a chatbot bolted onto a normal search bar.

• Shipping 6 visually distinct app themes from one shared design system in under 30 days, without each theme needing its own from-scratch design pass.

• Designing six different notification categories, new reward found, online-only reward, special promotions, affiliate offer, nearby reward, expiring soon, that stayed useful instead of turning into six sources of notification fatigue.

• Designed onboarding around two visible permission toggles, defaulted on but clearly overridable, with plain-language copy explaining exactly what each one does and why, instead of a generic "Allow Access" prompt.

• Built AI search as a set of predefined prompt chips routing to an AI-curated response, plus an "Ask AI" shortcut inside normal results, so it augmented the existing search instead of replacing it with an unfamiliar chat interface.

• Designed one token-based theme system, colour, iconography, and layout all swappable from a shared component library, so the same screens could ship in 6 distinct looks without redesigning each one from scratch.

• Gave each of the six notification types its own distinct visual treatment, and paired it with a wallet using quick-sort chips (Nearby, Online, Max Savings), so users could act on a notification or ignore it without feeling nagged.
