What's Included in App UI/UX Design
Most app projects go wrong long before development. Screens are designed on guesswork, the developer fills the gaps, and users find the confusing parts after launch, when every change costs ten times more. Our App UI/UX Design service fixes that at the cheapest stage: before code.
Every project includes:
- Discovery and user research: stakeholder workshop, user interviews, competitor app teardown and analytics review (for existing apps).
- Information architecture: navigation structure, screen inventory and content hierarchy.
- User flows: end-to-end journeys for onboarding, sign-up, search, checkout, booking, payments and every other task that matters.
- Wireframes: low-fidelity layouts to agree on structure before visual design begins.
- High-fidelity UI design: pixel-perfect screens for Android and iOS, including empty, loading, error and success states.
- Clickable prototype: an interactive Figma prototype you can use on your own phone and show to investors or stakeholders.
- Usability testing: sessions with real users to find friction, followed by a round of fixes.
- Design system: colours, typography, spacing tokens and reusable components.
- Developer handoff: specs, exported assets, icons, micro-interaction notes and Figma Dev Mode access.
Who is App UI/UX Design for?
- Startups and founders who need an investor-ready prototype or a validated MVP design before spending on development.
- Businesses with an existing app that has poor ratings, low retention or high drop-off at sign-up or checkout.
- SMEs and D2C brands launching their first customer app for ordering, booking or loyalty.
- Enterprises building internal apps for field staff, sales teams or operations that people actually adopt.
- Development agencies and in-house tech teams who need a dedicated design partner while they focus on code.
- SaaS companies extending their web product to mobile with a consistent experience.
What We Offer
- New app UI/UX design: from idea to complete, tested, developer-ready screens.
- App redesign: modernise an outdated app without confusing your existing users.
- UX audit: a heuristic and analytics review of your current app with a prioritised fix list.
- MVP and prototype design: a focused, clickable prototype for validation and fundraising.
- Design system creation: a scalable component library for teams shipping new features every sprint.
- Platform-specific design: native-feeling interfaces for Android, iOS, tablets and wearables, or one consistent design for Flutter and React Native builds.
- Dashboard and admin panel UI: the back-office screens that run your app.
What Makes Our App UI/UX Design Different
We test before you build. Every core flow is tested with real users on a clickable prototype. Fixing a confusing screen in Figma takes an hour; fixing it after launch takes a sprint.
We design for Indian users. Budget Android phones, patchy 4G, UPI-first payments, OTP logins, regional languages and first-time smartphone users are part of our brief, not an afterthought.
We design for conversion, not just for looks. Our performance marketing team works alongside our designers, so onboarding, sign-up and checkout screens are built around the numbers: activation, retention and revenue.
We design what developers can build. Our designers work next to our own Android, iOS and Flutter developers, so every screen is realistic, efficient to build and documented for handoff.

Our buyers in labs and industry used to call us just to check a spec. Now the full catalogue is online with exact details, and bulk enquiries come in with the right information from the start. Cartel Planet understood how a precision-parts business actually sells.
Ashwin GuptaDirector, Manufacturing company, Ambala · 26 days ago
We wanted to sell our honey, agarbattis and masalas directly and tell the hive-to-jar story behind them. Cartel Planet built a store that does both. Customers now see why our products are worth the price.

Sandeep SinghManaging Director, Real Estate Industry · 3 months ago
We sell software to schools, hospitals and labs, plus hosting, training and SMS. Our old site made everyone read about everything. Cartel Planet restructured it so each visitor lands on what’s relevant to them.
