Problem and audience
We define the product goal, target users, and the essential tasks to support.
Mobile App Design and Development
I turn your app's core tasks into user flows, screens and an interactive prototype. UI/UX design alone, or design and app development together, are both possible; programming, integrations and store release are agreed in the brief.
Mobile app UI/UX design that clarifies user flows, expresses the brand, and can be handed over to development in a structured way.
In mobile product design, user goals and decision points matter more than the number of screens. I define core scenarios, content hierarchy, and interaction behavior to create an experience that is clear, visually consistent, and ready for a structured handoff.
What can be included?
- Core user scenarios, flow diagrams, and information architecture
- Wireframes and high-fidelity UI for agreed key screens
- Reusable components and a focused design system
- When development is in scope, the iOS/Android app and store release; otherwise a complete developer handoff
How the work is scoped
The four things worth knowing before asking for a quote. No figures here — only what the figures depend on.
- What sets the scope
- The number of distinct flows rather than the number of screens. Empty, loaded, loading and error states inside a flow are design decisions too, and they are usually what grows the scope. The number of platforms adds to it.
- How it is delivered
- Ready to hand to development: a design file with components and their states, dimensions and colour values readable, a clickable prototype, and the icon and image assets required.
- How feedback works
- The flow and the direction of the main screens are approved first. Once the component structure exists, revisions apply to the component rather than to individual screens, which is why the direction sign-off is the critical step.
- What you need to start
- What the app does, the task the user has to complete, and any existing version or competitor examples. If you have a development team, knowing the technical constraints upfront makes this easier.
Inventory flows and states before counting screens
List the tasks users need to complete and the screens each task crosses. Sign-in, permissions, empty, loading, error and success states are separate decisions even within one screen. User roles, iOS/Android needs and existing product constraints also matter. Separating essential first-release flows from later ideas makes the proposed scope easier to assess.
What belongs in the prototype and developer handoff?
We agree which tasks the prototype demonstrates interactively and which states are explained in the design file. Handoff includes Figma screens, component states, dimensions and color values, required assets and behavior notes. A prototype is not a working app or completed user research; programming, research and testing requirements are scoped separately.
How to review OtoKonfor and MoodVerse
OtoKonfor illustrates bringing automotive services into one mobile experience; MoodVerse presents mood logging, characters, themes and reusable interface components. Compare task order, information density and component behavior rather than screen count alone. Your brief can include the product goal, priority flows, an existing design or product link, development team and target date.
Working process
Flow and prototype
Critical paths are reviewed through wireframes and an interactive prototype.
UI system, development and handoff
The approved flow becomes a visual system; when development is in scope, the app is built on it and prepared for release.
Who is it for?
A fit for teams visualizing a new mobile product or redesigning an existing app flow for greater clarity and consistency.
Frequently asked questions
What does the mobile app design service cover?
Core user scenarios, flow diagrams, and information architecture; wireframes plus high-fidelity UI design for key screens; reusable components and a base design system; and screen states with interface notes for developer handoff.
Is app development included?
Yes, depending on scope. UI/UX design with a structured developer handoff, or design together with iOS and Android app development, are both possible. Which platforms, integrations and store release are included is settled in the brief; the design and the build share the same screen system.
Is a clickable prototype provided?
Yes. Critical user paths are evaluated through wireframes and a clickable prototype, so the flow can be tested before visual design begins.
How does the mobile app design process work?
The problem and user are defined first: product goal, target users, and the core tasks to solve. Critical paths are then evaluated through wireframes and a prototype. Finally the approved flow becomes a visual system, organized for development.
Who is this service a fit for?
Teams making a new mobile product idea tangible, or rethinking an existing app flow so it reads more clearly and consistently.
How long does mobile app design take?
The timeline is set by the number of screens and flows and the product's complexity; a few-screen MVP and a multi-module app are different schedules. Scope is clarified in the problem-and-user step, and the timeline follows.
How is mobile app design priced?
Pricing is per project, driven by screen count, flow complexity, the scope of the component library, and developer-handoff needs. After the brief is clear, the proposal matches the agreed scope.
How does the revision process work?
Flows are approved first on wireframes and a clickable prototype; the visual system is applied to the approved flow. Structural feedback is resolved at the prototype stage, so UI-stage revisions focus on visual refinement.
Can I request a mobile UI/UX quote without a finished screen list?
Yes. The product goal, users' core tasks, any existing version and platform preference are enough to start. A flow and screen/state inventory can be prepared during discovery, with that work scoped separately from detailed interface design in the proposal.
