Top Mobile App UI Design Companies

Mobile app UI design studios produce the screens a development team builds from: user flows, wireframes, high-fidelity designs in Figma, clickable prototypes, a component library, and handoff specs. Companies hire them before a build so engineers are not guessing, during a redesign when ratings and retention have slipped, or when a dev team has no designer and the app looks like it.

Shortlist from this page by opening the apps a studio has designed on your own phone, not by looking at screenshots. Check whether the studio designs for iOS and Android conventions separately or skins one for both, what its Figma files look like at handoff, and whether its minimum project size fits a single flow or a full app.
