Mobile App Design for iOS and Android That People Keep Using
We design mobile apps around the first minute of use and the tasks people repeat every day: clear onboarding, simple navigation and screens that feel native on iOS and Android. Our mobile app design ends with tested prototypes and a design system your developers can build from.
What mobile app design includes
A good app is easy to learn and fast to use one-handed. These are the parts of the design work.
Research and user flows
Users, goals and competitors reviewed, then flows and an app wireframe drawn for the main tasks before any screen is styled.
Onboarding and navigation
A short first run and a navigation pattern that fits the app, so users find features without a manual.
UI in Figma
Mobile app UI design in Figma: iOS app design and Android app design that follow platform guidelines and your brand, with light and dark modes.
Prototypes and testing
Clickable prototypes tested with real users on real phones before development.
Accessibility
Readable text, large touch targets and contrast that works outdoors and for users with limited vision.
Handoff
A design system, assets and specs for developers, plus app icon design and store screenshots.
Why app teams choose us
App stores punish confusing first impressions. We design and test the first minute carefully.
Native feel on both platforms
We follow Human Interface Guidelines on iOS and Material Design on Android, and share what can be shared.
Retention in mind
Onboarding, empty states and notifications are designed to bring users back, not only to look good.
From design to build
The same company can build the app. See UI UX design services for research-led product work.
Scope fixed in writing
After a short call you get deliverables, schedule and price in writing before work starts.
How an app design project runs
Discover
We define users, key tasks, platforms and success metrics.
Flows and wireframes
We map the flows and sketch screens for the core journeys.
UI and prototype
We style the screens, build a clickable prototype and test it on phones.
Handoff
We deliver the design system and specs, and support the developers during the build.
Native, cross-platform or hybrid design
The technical choice affects design effort and how the app feels.
| Approach | Design effort | Best for |
|---|---|---|
| Native iOS and Android | Two tailored designs | Premium feel, platform features |
| Cross-platform | One shared design with small differences | Faster launch, shared code |
| Progressive web app | Responsive web design | Simple tools, no store |
| MVP | Core screens only | Testing an idea quickly |
| Mobile app redesign | Audit of the current app, then new flows and UI | Apps with low retention or an outdated look |
| App designer on demand | A designer embedded in your team | Teams that already have developers |
We recommend the approach after talking through your users, budget and timeline.

What good app design looks like in practice
Mobile design is constrained by a small screen, a thumb and a distracted user. We start with the main task and remove everything that slows it down. Onboarding is short, navigation is predictable and gestures follow platform habits. We design for push notifications, empty states and errors, because users meet them early, and we design dark mode from the start.
People search for this work as app UI design, iOS and Android design, mobile UX design or an app design agency, and the scope is the same: flows, screens, prototypes and handoff. We work in Figma, test prototypes on real phones and check typography and spacing against platform guidelines. We also prepare app store screenshots and the icon, since they influence installs.
Cost depends on the number of screens, the platforms and the amount of research and testing. App design cost is agreed in writing after a scoping call, and teams that want to hire app designers from us receive a scope, a schedule and a price. If you also need development, the same team can build the app from the approved design system. Teams comparing an app design company, an app design agency or a mobile design studio should ask for the scope and the price first, and an app designer in our team works in Figma from wireframe to handoff. App design services also cover a redesign of an existing app, and the question of how much it costs to design an app is answered in writing before work starts.
Questions we get on the first call
What does mobile app design include?
User flows, onboarding, navigation, UI for iOS and Android, prototypes, usability testing and a design system with specs for developers.
How much does app design cost?
The price depends on the number of screens, platforms and research. We fix it in writing after a short scoping call.
Do you design for both iOS and Android?
Yes. We follow each platform's guidelines and share components where it makes sense, so the app feels native and stays consistent.
Can you design an MVP?
Yes. We can design only the core screens first, so you can test the idea before investing in the full product.
Do you test on real phones?
Yes. Prototypes are tested with users on real devices, which shows problems that desktop previews hide.
Can you also build the app?
Yes. The same team can develop the app from the design system, or hand the design to your developers.
Do you redesign existing apps?
Yes. We review the current flows, analytics and reviews, then redesign onboarding, navigation and the screens that lose users.
Do you design the app icon and store screenshots?
Yes. App icon design and app store screenshots are part of the handoff, because they influence installs.
