Mobile app design for iOS and Android
How the design process runs
Planning first. Your technical Project Manager documents the full picture before design starts: every screen (login, home, notifications, settings, and the rest), the core functionality and user flows, the technology choice (native iOS or Android, or cross-platform with .NET MAUI or React Native), and the backend architecture the app will need.
Concept and mockups. App UI design starts with designers conceptualizing the interface around your app's purpose and users, then designing every screen defined in the plan, following each platform's conventions: Apple's Human Interface Guidelines for iOS, Material Design for Android. Building for both? The designs keep your brand consistent while respecting each platform's language.
Interactive prototypes. You get a clickable prototype to test on an actual device: navigate the screens, evaluate the flow, share it with stakeholders. Prototypes demonstrate interface and navigation, not backend functionality; they exist to validate direction before development spends money.
Live refinement. We meet online, you comment, and the designer implements changes in real time; sessions often end with an updated prototype the same day. Colleagues can join on short notice, something a physical meeting can't offer.
All designs are made in Figma, so you receive editable source files, interactive prototypes, and developer-ready specifications that work with any development team, including ours.
What's included
Every major screen designed to research-backed standards; custom icons and touch-optimized buttons and controls; navigation consistent with your brand; and a visual hierarchy that guides users to their goal with minimal friction. Optional additions: App Store and Google Play promotional graphics and screenshots, and a companion website (designed and developed by us) that explains the app, supports users, and builds credibility before download.
Native or cross-platform, we design for both
Native apps (separate iOS and Android codebases) deliver maximum performance and full platform features; cross-platform apps (.NET MAUI or React Native) share one codebase and reduce development time with near-native performance. The design process is the same either way, and we design for the constraints and opportunities of your chosen approach.
Our designers train with the Interaction Design Foundation and the Baymard Institute, evidence-based UX research organizations, and they work directly alongside our developers, so every design is technically feasible and maintainable, not just attractive.
Two ways to work with us
Continuous Monthly Development: Send tasks whenever they arise. With Care, everything runs in writing at one fixed monthly price: no estimates to approve, no cost overruns.
Care Plus gives you everything in Care at its own fixed monthly price, plus up to two hours of meetings per month with a Project Manager or any 1902 Software expert (for planning, advice, and technical discussion), up to two ongoing tasks at a time, and up to two developers working on your tasks at the same time.
Care Ultimate is for ongoing engagements, often across multiple systems, that need close collaboration: a fixed price for every task or group of tasks, approved by you before work begins, people with the right expertise added to your project as your needs grow, and meetings with any 1902 Software expert whenever you need them (billed at the going project management rate for the actual time spent).
Fixed Price Projects: For a single, well-defined app project (a new build, a major upgrade) you get one agreed price for the whole thing, fixed before work begins.
Large projects typically start with a Project Scoping phase at an agreed, prepaid fixed price. The purpose is to precisely define what will be built and to establish the final price. This ensures full clarity for both you and us before development begins.
How we use AI
Our designers use modern AI-assisted tools in exploration and production, and every design is thoroughly reviewed, tested, and verified by experienced designers and testers before delivery.
Free, no-commitment
Commonly asked questions
Do you design for iOS, Android, or both?
Whichever your project needs. For both platforms, the designs stay brand-consistent while following each platform’s own conventions.
How functional are the prototypes?
You can click through every screen and evaluate the flow on a real device; backend functionality (data, accounts, purchases) comes with development.
Is development included?
Our app design services and development are separate. Our in-house team can build from the designs with no handoff friction, or your team gets the Figma files and specifications.
How long does app design take?
It depends on the number of screens and flows; the live sessions compress revision cycles substantially, and you get the timeline with the fixed price during planning.
What do we need to provide before design starts?
Your app concept and goals, brand guidelines if you have them, and input during planning. Your technical Project Manager turns that into the screen list and specifications the designers work from.
Do you design app store graphics too?
Yes, as an optional addition: App Store and Google Play promotional graphics, screenshots, and feature highlights.
