Zethic is a mobile app design agency that treats iOS and Android as genuinely different design problems, not one interface stretched across two platforms. Our mobile UI/UX design work runs from user research through visual design to a build-ready handoff.

What you get from this work.
Our mobile app design services move through stages: research and structure, then platform-specific visual design, then a build-ready handoff. For products needing deeper research first, our user experience design services cover that discovery.
User-centered research grounded in how people use a phone.
User-centered app designUser interviews & testingJourney mappingCompetitive app audit
Good mobile UI/UX design starts with user-centered app design, watching how people actually try to complete tasks on a phone. A flow that fails on a five-inch screen looks fine in a desktop mockup.
Navigation and flow tested while changes are still cheap.
App wireframing & prototypingLow & high-fidelity wireframesClickable prototypesInformation architecture
Structure gets decided here, before visual polish, using app wireframing and prototyping to test navigation while changes are cheap. If deeper validation is needed first, our prototype development services cover that stage.
Platform-specific UI, typography, and touch targets.

We design for iOS and Android conventions as genuinely separate disciplines, not a shared template with a different icon set, a mismatch we cover in our mobile app development trends roundup.
Specs engineers can build from, in a system built to scale.

Design that never reaches engineering intact gets rebuilt from memory, one guess at a time. We hand off specs engineers can actually build from, in a system built to hold together as the app grows.
UI UX Design Services, our team for the research and structure behind every interface.
Why teams pick us for this.
Shipping one interface for both platforms is cutting a corner users notice immediately. We design against each platform's real conventions.
Our mobile app design services document components and patterns so the app stays consistent after the tenth feature request, not just the first release, the same governance our dedicated user interface design services apply to any product.
Handing off a Figma link without documented states and edge cases is not finishing the job. We ship specs engineering can actually build from.
QA and design system maintenance are part of the same scope, connecting to the broader shift we've tracked in the mobile app development market.
This is the discovery phase every mobile app design project starts with, and it is how our services, part of Zethic's broader AI and digital solutions, move to a shipped, platform-appropriate app.
Talk to us{ 01 }· Week 1-2
We interview users, review analytics, and map the current or planned experience end to end, grounded in user-centered app design from the start.
{ 02 }· Week 2-4
App wireframing and prototyping happen here, tested with real users before visual design starts, so structural problems surface early.
{ 03 }· Week 4-8
Platform-specific screens and a documented design system get built out, then handed off with the specs engineering needs.
{ 04 }· Ongoing
We stay through the build to catch drift between the design and the shipped app, then keep testing and refining after launch.
Questions, answered.
Separately. iOS and Android app design follows genuinely different conventions, from navigation patterns to touch targets, so shipping one shared design for both platforms is cutting a real corner.
Cost depends on scope: a single-platform app with a handful of screens costs less than a full iOS and Android design system with a complete component library. Most projects are quoted after a short review.
A focused project, like wireframes and design for one platform, usually runs four to six weeks. A full iOS and Android build with a documented design system typically runs eight to twelve weeks.
Yes. Most redesign projects start with our design audit services on the current app, since a redesign built on an unclear diagnosis usually repeats the same usability problems in a new interface.
Handoff is part of the same project scope: specs, states, and component documentation ship with the design, and our team stays available through the build, closing the gap so many shipped apps drift into.

Tell us the app
What it does, which platforms, and where it's already drifted. We sign an NDA first.
Platform-specific, not shared
A senior designer builds for iOS and Android conventions, not one shared template.
Handoff that actually ships
Specs engineers can build from, plus a system that scales past launch.
