microfeller® studio designed this mobile app UX for Surveys, a mini-app on the World Network where users earn Worldcoin by responding to short questions.

The design brief behind Surveys was clear: make earning feel effortless. microfeller® studio, working alongside collaborators Ilya Murashko and Alex Kush, created a mobile app UX that sits inside the World Network—Sam Altman’s human-verification ecosystem—and serves two audiences at once. Regular users open the app, pick a survey, answer a few questions, and pocket Worldcoin directly into their World App wallet. Businesses get a manager console to build and launch custom surveys and pull results as CSV exports. The interface has to speak fluently to both sides without feeling cluttered or compromised.

What sets the visual direction apart is its deep, almost midnight navy background, lit by sweeping teal and cyan gradient accents. This is not the blank white canvas typical of survey tools. The dark base makes the glowing card elements feel focused and premium, directing the eye to the action on screen. Survey cards surface with readable type, estimated completion time, and a clear earnings figure—everything a user needs to decide in under three seconds.

The mobile app UX behind the two-sided survey experience

Navigation stays simple. A persistent bottom bar with icon tabs and an active-state highlight pill keeps orientation clear throughout the flow. The onboarding sequence uses step-progress indicators and a calm, linear path—no unnecessary friction between signup and first survey taken. Survey questions appear in a single-focus format: one question per screen, with large touch targets and no visual noise around them.

The business side of Surveys operates in a different register. The manager console presents survey creation as a structured grid of question-format options, letting operators choose from multiple-choice, rating scales, or open text without consulting documentation. Results display in a clean data view with export controls positioned at the top. The entire experience—from survey build to insight download—is compressed into a focused, distraction-free workspace.

What microfeller® studio achieved with this mobile app UX is a product design that earns trust from both sides of a two-sided market. The consumer interface feels like a rewards app. The business interface feels like a lightweight analytics tool. The visual language—dark backgrounds, teal gradients, rounded card modules, and high-contrast type—holds both experiences together under one coherent design system. Every screen in this mobile app UX carries the same intention: minimal, purposeful, and built for speed. That coherence is what makes Surveys feel like a finished product rather than a prototype.
