Most apps are downloaded once and opened twice. We design for the second month, not the first session: flows that solve a real job, interfaces that feel native on both platforms, and prototypes tested with real users before development spends a rupee. Handoff is clean enough that your engineers build exactly what was validated.
The job the app does, for whom, and against which competitors, defined before design begins.
Every journey from open to outcome mapped and paper-tested, so structure is settled before styling.
Native-feel interfaces for iOS and Android that make the brand tangible on a five-inch screen.
A component library both platforms share, so the product scales without the design drifting.
High-fidelity prototypes that feel like the shipped product, testable on real devices early.
Real users, real tasks, before development. The cheapest bugs you will ever fix.
Feedback, delight, and orientation through motion, used purposefully rather than decoratively.
Specifications, assets, and prototypes engineered for clean implementation, with support during build.
Five stages, one goal: an app that earns daily use, validated with real users before a line of code ships. Proven on consumer and fintech products across five countries.
Users, context, and competition researched until the core job the app must do is beyond debate. Two weeks, complete picture.
Journeys and screens structured and paper-tested with the team before any visual design.
Native-feel UI and a shared design system built for both platforms together.
Interactive prototypes on real devices, tested with users, iterated until tasks succeed.
Annotated specs and pairing with engineering through build, so what ships is what tested.
Agentic app design puts autonomous AI agents inside the product workflow. They generate screen variants inside the design system, run unmoderated usability studies at scale, and audit every flow against platform guidelines. At Grapes, every agent workflow ends at a human desk, where a named product designer reviews, corrects, and approves before anything reaches your users.
Agents produce screen and flow variants within the design system for designers to curate.
Agents run unmoderated studies across users and synthesize task success data.
Agents check every screen against Apple and Google platform guidelines.
Agents audit contrast, touch targets, and screen reader support continuously.
Agents compare built screens against specs and flag drift instantly.
Dashboards linking design changes to retention and task success, in plain language.
What changes for you
AI multiplies our output. It never replaces our judgment.
The questions CXOs ask us before signing, answered straight.
App design covers product discovery, user flows and wireframes, UI design for iOS and Android, the design system, interactive prototypes, usability testing, motion design, and developer handoff. The goal is an interface people use daily and your engineers can build without guesswork.
Platform conventions, interaction depth, and the retention battle. Apps live or die by daily use, so we design for the second month: faster flows, native gestures, and feedback loops. The testing bar is also higher, because app store reviews punish clumsy releases publicly.
Yes, as one design system with platform-specific adaptations. Shared tokens and components keep the brand and logic consistent, while each platform gets the navigation, gestures, and feel its users expect.
Regularly. We audit the current experience, design within or alongside your existing system, and hand off in whatever form your engineers consume best, with pairing sessions during build so intent survives translation.
A full design cycle from discovery to developer-ready handoff typically runs 6 to 10 weeks per major product area. Prototypes arrive in week three or four, so you can test direction long before the full system lands.
Agentic app design puts autonomous AI agents inside the product workflow. They generate variants inside the design system, run usability studies at scale, and audit platform guidelines continuously. Every agent workflow passes a human checkpoint where a named designer approves what ships.
Three reasons clients cite. Our design work helped grow app installs 189% for WazirX alongside ASO. Research, design, and engineering sit in one team, so handoff never eats the intent. And we measure design in retention and task success, from five offices worldwide.
