The Problem
What I did
Built the product from scratch, esearch, information architecture, UX writing, visual design, and developer collaboration through build. The core strategic decision was to flip the standard onboarding sequence: show value first, ask for an account second. Most cashback apps front-load a registration wall before users have any reason to care.
Beyond onboarding, every feature was designed around the same trust principle, a cashback flow reduced to three steps, four clearly differentiated receipt statuses to eliminate post-scan anxiety, a wallet with a visible progress indicator toward the withdrawal threshold, and notifications tied to opt-in preferences rather than volume.
Trust isn't a feature, it's the architecture. Every drop-off point in a cashback app is a trust failure in disguise: unclear status, unexpected friction, ambiguous next step. Designing for clarity at each of those moments wasn't a UX decision, it was a retention decision.
VALIDATION
App Store/Google Play reviews are one of the clearest signals of whether a product's UX is working. A 4.6★ average across millions of downloads suggests the trust-first design strategy landed, users found the experience clear enough, reliable enough, and valuable enough to come back and tell others.
