Thumb-first. Platform-native. Kept-installed.
Mobile UX fails at the seams between platforms: designs that look correct in Figma but feel wrong on a real device, iOS navigation patterns applied to Android and vice versa, touch targets that are pixel-perfect on a 375pt canvas but impossible to tap accurately in the real world, and onboarding flows designed by people who've never watched someone use an app for the first time on a bus. We design mobile apps with the platform constraints built in from the first frame — and we test every design on physical devices, not just device frames in Figma.
Mobile app UI/UX design at Origin Softwares is built around platform conventions and physical device constraints, not Figma device frames. We design for iOS and Android as distinct platforms with their own navigation models and interaction patterns, test prototypes on real hardware from the wireframe stage, and deliver handoff files with platform-specific annotations that prevent implementation errors. Clients choose us because we have the platform knowledge and physical testing discipline that produces apps that feel genuinely native on both platforms.
What makes mobile UI/UX design different from web or desktop design?
Mobile design operates under constraints that web design does not. The interaction model is gesture-based rather than cursor-based, which changes how navigation, scrolling, and actions are designed. Platform conventions — iOS Human Interface Guidelines and Android Material Design 3 — define user expectations for how the phone responds, and departing from them produces apps that feel unfamiliar. Touch targets must be large enough for accurate tapping under real-world conditions, not just pixel-perfect in a design tool. Origin Softwares tests all wireframes and prototypes on physical devices, designs explicitly for both iOS and Android conventions, and delivers platform-specific annotations in every handoff.
The problems this solves
- Designs look correct in Figma device frames but feel wrong when tested on a real phone due to unaddressed platform-specific constraints
- iOS and Android receive the same design file without platform-specific interaction patterns, resulting in an app that feels foreign on one or both platforms
- Onboarding flows are designed by people who know the app deeply and fail to account for how users experience it for the first time on a bus with divided attention
- Loading and offline states are treated as afterthoughts and either missing from the design or inconsistent across the app
- Touch targets are sized for visual proportionality in design tools rather than for accurate tapping under real-world conditions
- Premium design intent is lost in implementation because micro-interactions and transition behaviours were never specified
Business outcomes
- Higher App Store ratings when the app follows platform conventions correctly and delivers the interactions users expect on their operating system
- Reduced development iteration cycles when prototypes are tested on physical devices before handoff rather than after implementation begins
- Lower uninstall rates when onboarding gets users to first meaningful action quickly and without friction
- Reduced support contact related to navigation confusion when gesture-based navigation follows platform conventions
- Faster time to first action because thumb-zone-optimised layouts put primary actions where users can reach them one-handed
- Stronger perception of quality from users when micro-interactions and transitions are designed explicitly rather than using platform defaults

When Mobile App UI/UX Design may not be the right fit
We'd rather tell you upfront than waste your time and budget.
- You only need a mobile-responsive web experience rather than a native app — responsive web design is a different service
- Your app's primary differentiator is backend capability or data rather than user experience — if the interface is secondary, a lighter-touch design engagement may be more appropriate
- You have very limited ability to provide real users for testing — physical device testing is central to our quality standard and cannot be replaced by design tool simulation
- You are rebuilding an existing app with no design changes — if the existing designs are validated and only the implementation needs work, you need development rather than design

How long does a mobile app design project take?
A focused mobile app design engagement at Origin Softwares — covering one primary user journey, both iOS and Android designs, and a tested prototype — runs six to ten weeks. A full app with multiple user roles, onboarding flows, complex feature sets, and App Store asset production runs ten to sixteen weeks. The timeline is driven by the number of core user flows and the depth of research required. We provide a project-specific estimate after a discovery call and hold to the agreed timeline through milestone-based reviews. Physical device testing begins at the wireframe stage, typically in week two or three of the engagement.
Technologies we use
- Figma
- Framer
- Maze
- UserTesting
- Lookback
- Principle
- ProtoPie
- Zeroheight
Architecture & scalability
- Navigation architecture must be designed separately for iOS (tab bar, push navigation, modals) and Android (navigation bar, bottom navigation, drawers) — using the wrong model on either platform produces immediate usability issues
- Design token architecture for mobile should include platform-specific overrides for system font, default border radii, and shadow treatment at the semantic layer
- Gesture specification must distinguish between platform-native gestures (iOS back-swipe, Android back button) and custom gestures, with fallback behaviour defined for each
- Touch target size enforcement requires a separate review pass — visual proportionality in design tools does not guarantee 44pt iOS minimum or 48dp Android minimum compliance
- Loading and offline state design should be specified at the screen level, not just at the component level — the app's overall behaviour during network degradation should be a documented design decision
- App navigation depth should be audited at the information architecture stage — more than three levels of navigation depth on mobile requires a fundamental rethinking of the hierarchy, not just deeper navigation

Why Origin for Mobile App UI/UX Design
Physical device testing — not just device frames
A design that looks correct in a Figma device frame can feel wrong on a real device. We test wireframes and prototypes on physical iOS and Android hardware before we go high-fidelity.
Platform conventions implemented correctly
HIG compliance on iOS and Material Design 3 on Android are not suggestions. We implement them correctly — users notice when apps don't follow the platform they're on.
Micro-interactions and transitions designed explicitly
Premium mobile feel comes from designed interactions, not default transitions. We prototype spring-physics animations, haptic feedback moments, and gesture responses before handoff.

Before you start — a checklist
Use this to prepare for your first conversation with us.
- Are you building a native app or a mobile-responsive web experience? Native app design requires platform-specific expertise that web design does not.
- Do you need both iOS and Android? Both platforms have distinct conventions that require separate design decisions — confirm the platform scope before starting.
- Is your primary target audience consumer (daily personal use) or enterprise (professional field use)? The design priorities differ significantly.
- Do you have access to real users for physical device testing? Our testing standard requires participants using the prototype on actual hardware.
- Is this a new app or a redesign of an existing one? Redesigns require an audit of existing user habits that shapes the change approach.
- Does the app need to work offline or in low-connectivity environments? Offline state design is a distinct requirement that must be scoped explicitly.
Maintenance & support
- Post-handoff support window for platform-specific implementation questions from the development team
- Mid-build implementation review to verify platform conventions are being built correctly
- Post-launch App Store review analysis and user feedback synthesis for iteration planning
- Feature addition design retainer for teams shipping new features that need to stay within the established design system
- Annual platform compliance review when major iOS or Android platform updates change convention requirements
“We'd had two other design agencies on this app. Both produced beautiful Figma files that felt wrong the moment you used the prototype on a phone. Origin tested on real devices from week two. The difference was immediate.”
Frequently asked questions
Planning & scope
- How much does a mobile app design project cost?
- A focused engagement covering one or two core journeys, both iOS and Android, and a tested prototype runs ₹5–10 lakh. A full app design with multiple user types, onboarding, complex feature sets, and App Store assets runs ₹12–25 lakh. We provide a fixed-price proposal after a scoping call.
- Do we need to design both iOS and Android from the start?
- If you plan to launch on both platforms, designing them together is significantly more efficient than designing one first and adapting it later. The navigation model decisions made early in the engagement are platform-specific and affect the entire design — retrofitting Android conventions onto an iOS-first design produces a sub-standard result.
- How early in the project should we involve design?
- Before the app architecture is decided. Navigation model, screen hierarchy, and core user flow decisions made by engineers before design starts can significantly constrain the user experience. The most effective engagements start with a design discovery workshop that informs the technical architecture.
- We have wireframes already — can you start with visual design?
- If the wireframes have been validated with real users on physical devices and the navigation model is platform-correct, we can start at the visual design stage. If the wireframes were produced in a tool without device testing, we recommend a review and validation step before visual design begins — visual redesign of a structurally flawed flow is expensive to redo.
Technical
- What file format are the final designs delivered in?
- All designs are delivered in Figma with separate pages for iOS and Android. Platform-specific annotations are included inline. We also deliver the interactive prototype link and, for complex micro-interactions, reference video recordings of the prototype behaviour.
- How do you specify micro-interactions for developers?
- We provide timing specifications with duration in milliseconds, easing curve values, and trigger conditions for every micro-interaction. For spring-physics animations, we specify stiffness, damping, and mass values. For complex sequences, we produce Framer or ProtoPie prototypes as reference implementations so developers have a direct model to match.
- Do you design for different screen sizes within iOS and Android?
- Yes — we design for the minimum and maximum screen sizes within each platform range. For iOS, that typically means iPhone SE (375pt) and iPhone 14 Pro Max (430pt). For Android, minimum phone size (360dp) and common large phone (412dp). Auto-layout in Figma handles intermediate sizes; we validate the extremes.
- How do you handle designs for dark mode?
- We design light and dark mode variants using a semantic token layer where components reference contextual colour tokens rather than primitive values. Switching between modes is a token-level change that propagates across all components. Dark mode designs are delivered as a separate Figma page or as toggle variants using Figma Variables.
Engagement & process
- Who owns the final design files?
- All design files become the client's property upon full payment. We retain the right to reference the work in portfolio contexts unless a specific NDA or app confidentiality requirement prevents it.
- Can you work with our existing brand guidelines?
- Yes — in most cases we receive brand guidelines from the client and adapt them for mobile platform conventions. Mobile design constraints (minimum touch targets, platform-specific component conventions, small screen information hierarchy) sometimes require adapting brand elements that work in print or web contexts but do not translate well to native mobile.
- How do you handle App Store submission requirements?
- App Store screenshot and listing design is a standard deliverable. We produce screenshots in all required device sizes and aspect ratios for both App Store and Google Play. We do not handle the submission process itself — that is a development team function — but we provide all design assets at the specification the stores require.
- What happens if the platform guidelines change after delivery?
- Major iOS and Android platform updates sometimes change conventions that affect existing app designs. We flag anticipated platform changes during the engagement if they are already announced. Post-delivery platform updates are scoped as a maintenance engagement — a platform compliance review and update — rather than being covered in the original engagement.
Should we design iOS and Android separately or use one universal design?
We design a shared visual identity — one colour system, typography scale, and component library — but implement it with platform-correct interaction patterns for each operating system. Navigation on iOS uses bottom tabs and back-swipe gestures; Android uses a navigation bar and back button. Dialogs, pickers, and switches follow different conventions. Typography defaults and system font sizes differ. Users who use both platforms notice when an app does not follow the conventions of the platform they are on. Origin Softwares delivers iOS HIG-compliant and Material Design 3-compliant versions as distinct but visually consistent designs. The two platform files are delivered in parallel, with a shared base component page referenced by both, keeping design changes in sync.
