Your App Loses 77% of Users in 3 Days. We Design the Fix.
Bad onboarding ends apps before users reach the feature they downloaded for. Redefine is a mobile app design company that maps your user's path to the moment they get value. Then we build the design system that keeps them coming back.
The app users delete and the one they open daily. Here is the only difference.
7 navigation items on screen, user cannot find the core action
3 different button styles, 3 different blues, no design system
Touch targets under 24px, fingers miss them on first tap
Loading... (no skeleton, no progress, no feedback)
Single primary action, above-the-fold, 44px+ touch target
Skeleton states signal loading, user knows the app is working

77% of users leave within 3 days. Bad onboarding is the cause.
Most apps ship the core feature but skip the path that leads users to it. Without research-driven onboarding, users hit a wall and leave before finding the value.
No design system means every new screen starts a new argument.
Inconsistent buttons, mixed spacing, and conflicting colors slow your engineers. They create friction users feel without knowing why. Users stop trusting the app.
Vague developer handoffs cost 3 to 5 weeks of rework.
Designs without annotations, spacing grids, and component specs force developers to guess. Their best guess rarely matches design intent. Your launch date slips.
Redefine delivers a research-backed design system, a fully annotated handoff, and a test-ready prototype. Your engineers build once. No revision cycles on intent.

Brief to Developer Handoff in 6 Weeks
You see real wireframes in week one. Each sprint ends with a deliverable your team can review, test, or hand to engineers. Nothing is skipped to hit the timeline.
Week 1
Research + Discovery
We review your brief, audit your competitors, build user personas, and agree on the metrics that define success. You receive a research report, not assumptions.
Week 1 to 2
Screen Architecture + User Flows
Every screen in your app gets mapped before a pixel is designed. Routes, roles, and decision points are defined. You know exactly what gets built.
Week 2 to 4
Design System Build
A shared component library with color tokens, type tokens, and interaction states. Your engineers get a single source of truth. No guessing, no rework.
Week 4 to 5
Interactive Prototype
High-fidelity screens and a clickable prototype your team tests on a real device. You review flows before a line of code is written.
Week 6
Developer Handoff
120+ annotated Figma frames, 94 design tokens, spacing specs, motion guidelines, and accessibility documentation. Your engineers build without opening a Slack thread to ask what something means.

Prototype link shared with your team. Test on any device before development starts.
Zero-interpretation handoff. Your development team builds directly from annotated Figma. No back-and-forth on intent.
Scoped before work starts. Priced by deliverable, not by the hour. No commitment to receive a proposal.
Your proposal includes every screen, every deliverable, and a fixed total cost. No surprises.
One design system. iOS, Android, React Native, and PWA. All from the same source.
Redefine builds platform-agnostic design tokens first. iOS and Android implementations derive from the same Figma file. You get two production-ready outputs from one sprint, not two separate projects with two separate bills.

Every deliverable your app needs, in one six-week sprint.
User Research + Information Architecture
We start with users, not screens. Persona documentation, competitive audits, and user flow maps come before any visual work. Your information architecture defines every screen and decision point before design begins. This means you are not paying to redesign screens that should never have been built.
Native iOS + Android Design
Built to iOS Human Interface Guidelines and Android Material You specs from day one. No retrofitting. No compliance fixes after handoff. Both platforms come from one sprint sequence.

Interaction + State Design
Every tap, swipe, and transition is designed. Loading states, error states, and empty states are documented before a line of code is written. Your engineers do not encounter gaps. Your users never hit a broken state.
- Onboarding flows
- All loading and error states
- Gesture and motion specifications
Zero-Interpretation Developer Handoff
Annotated Figma files. Design tokens. Spacing grids. Component specs. Motion guidelines. Your engineers build directly from the handoff. No Slack threads asking what a button's active state looks like. No revision cycles on intent.

Accessibility
A multi-role mobile platform. Redesigned. Delivered in 6 weeks.
DrivingI serves driving schools, instructors, and students. Instructors work from mobile devices in the field. Students book and pay from phones. Admins manage fleets from a web dashboard.
The portal had no mobile design system. Instructors could not complete core tasks on phones, which drove high support volume. Students hit a 60% drop-off at the payment screen. Admin views were desktop-only and broke on any mobile device.
60%+ drop-off at payment screen
No mobile design system across 3 user roles
A mobile-first redesign across three user roles: student, instructor, and admin. A new design system with annotated components, gesture specs, and platform-native patterns. The onboarding flow was rebuilt from user research, not assumptions. Headless ecommerce handled lesson package purchase. Developer handoff was zero-interpretation.
User flows designed and handoff-ready across 3 roles, delivered in 6 weeks
120 annotated Figma frames. 94 design tokens. iOS and mobile web implementation guides. The development team built from handoff without revision cycles on any design intent. The payment screen drop-off had a clear, research-backed fix designed into the flow.
Four things every mobile app design agency promises. Here is how we prove each one.
Mobile-First. Not Mobile-Adapted.
Most design agencies build for desktop, then squeeze the layout onto a phone. Redefine starts at 375px. Mobile touch targets, mobile performance budgets, and mobile navigation patterns are the design foundation. Desktop views are derived from mobile, not the reverse.
Every component is reviewed and approved at 375px viewport before desktop work begins.
iOS + Android in One Sprint Cycle.
Two separate projects for iOS and Android double your timeline and your budget. Redefine builds one platform-agnostic design system and derives both implementations in the same sprint. One brief. Two handoff-ready outputs.
iOS and Android Figma variants are delivered side by side, same component, both platform implementations, in one file.
A Clickable Prototype at Every Sprint Review.
You will never review a static PDF from Redefine. At every sprint review, you get a Figma prototype that runs on a real device. You tap through the actual flow. Feedback is grounded in how the app feels to use, not how it looks in an export.
Sprint prototypes cover onboarding, the core task flow, and error states. Not just the happy path.
Handoff with Zero Developer Interpretation.
Most agencies ship screens. Redefine ships the reasoning behind every screen. Spacing annotations, token names, interaction logic, state definitions, gesture specs, and platform safe zone guidance. Developers build the first time, correctly.
Incomplete handoffs create revision cycles. Those cycles cost your launch date. The Redefine handoff eliminates both.
Questions buyers ask before signing a mobile app design engagement
Every engagement covers six deliverables. First: a user research report with persona documentation. Second: user experience architecture with complete user flow maps. Third: a Figma design system with all components and design tokens. Fourth: high-fidelity screens across every required platform viewport. Fifth: a clickable prototype for each sprint review. Sixth: a full developer handoff with annotated frames, spacing specs, motion guidelines, and accessibility documentation. Scope is confirmed in writing before Sprint 1 begins.
Redefine designs for iOS, Android, or both in one sprint cycle. The design system is built platform-agnostically first. Platform-specific Figma variants then derive from that single system for iOS (Human Interface Guidelines) and Android (Material You). React Native and Flutter projects receive both implementations from the same source. Specify your platform targets in the brief. The proposal scopes to exactly what you need.
Responsive web design adapts a web layout to fit smaller screens. Mobile app design starts from scratch with native patterns: gesture navigation, hardware button behaviors, platform safe zones (like the iOS Dynamic Island), offline states, push notification flows, and app store submission requirements. The component libraries and navigation systems are entirely different. Using a responsive web design system for a native mobile app produces an app that looks like a website. It performs like one too.
A standard engagement completes in 6 weeks. Research and discovery run in week 1. Screen architecture and user flows run weeks 1 to 2. Design system and core screens build through weeks 2 to 4. The interactive prototype arrives in weeks 4 to 5. Developer handoff delivers in week 6. Scope and timeline are fixed before Sprint 1. If you have a hard launch date, flag it in your brief. The sprint sequence is built around it.
Priced by scope, not by the hour. Your proposal lists every deliverable and a fixed total cost before Sprint 1 begins. Cost is based on user role count, screen count, platform targets, and research depth. See current pricing at the pricing page. Submit your brief for a scoped proposal within 3 business days. No commitment needed to receive it.
This service is built for a specific type of project. Here is how to know if yours qualifies.
- You are building a native iOS or Android app and need UX/UI design from research through developer handoff
- You have an app with poor retention or high drop-off in a key flow and need a research-driven redesign
- Your engineers can build from annotated Figma files and a design token system — or will be able to by handoff
- You can dedicate 2 to 3 hours per week for sprint reviews and async feedback on prototype screens
- You need development alongside the design. This engagement covers design only. Redefine delivers the design. You bring the engineers.
- You need 3D graphics, motion design, or game UI. Those are specialized disciplines outside this engagement.
- You want to skip user research and go straight to screens. Research is not optional. It is the reason the screens work.
