iOS app design services built to pass App Store review and keep users coming back
An iOS app that fails App Store review, loses users in the first session, or cannot scale a component library is an iOS app design problem, not a development one. Redefine delivers Human Interface Guideline-compliant iOS app UI design, interactive Figma prototypes, and a complete component library your team can build from and extend.

Most iOS apps lose users before the second launch
77%
of users abandon an app within 3 days of first download
Poor onboarding, unclear navigation, and confusing interactions are the leading causes
33%
of iOS apps are rejected on first App Store submission
HIG violations, missing accessibility, and incorrect metadata are the top rejection reasons
5s
before a user decides to keep or delete your app
The first screen is the only screen that matters for retention decisions
What teams tell us before engaging Redefine
"Our developer built the app from spec but users cannot figure out the navigation. We got rejected by the App Store twice. We have a product that works but nobody wants to use it."
That is an iOS design problem. HIG violations, unclear information architecture, and missing usability testing all produce the same result: an app that technically functions and behaviorally fails.
Navigation patterns that violate iOS conventions, users cannot find core features
Tap targets smaller than 44px, App Store rejection and user frustration
No Figma component library, development guesses at states, variants, and edge cases
From app brief to App Store-ready design in 6 weeks
Every milestone is agreed before Sprint 1. You see each deliverable as it develops, not all at once at the end.
Week 1
Discovery and user research
Brief review, competitor audit, user persona development, and key flow mapping
Week 2
Information architecture and flows
Navigation structure, user journey maps, and screen-level flow documentation
Weeks 3 to 4
Wireframes and low-fidelity prototype
Low-fidelity screens for all primary journeys, stakeholder review, and approval gate before high-fidelity
Weeks 4 to 5
High-fidelity iOS UI design
Pixel-perfect iOS screens, HIG compliance review, component library, and color system
Week 6
Prototype, handoff, and App Store assets
Interactive Figma prototype, developer specifications, App Store icon, and submission screenshots
User personas (3 defined)
Primary: Active commuter, 28 to 34
Secondary: Weekend user, 35 to 45

Every iOS app UI design project ships these five things
HIG-compliant iOS app UI design
Every screen follows Apple's Human Interface Guidelines: safe area insets, Dynamic Type, 44px tap targets, and SF Symbols. The design will not require rework when the App Store reviewer applies their standards because we applied them first.
Dark and light mode
iPhone and iPad layouts
All viewport sizes
Accessibility ready
Figma component library
Auto-layout components for every iOS UI design element. Every state, variant, and interactive behavior documented. Your developer opens the file and has zero questions.
Interactive prototype
Test every flow before development begins. Click through the full app experience in Figma. Catch navigation problems when they cost zero hours of developer time to fix.
App Store asset kit
App icon at every required resolution. Screenshots at every required device size. Preview screen copy. Every asset formatted to Apple's current submission requirements so your developer does not need to do it.

On the Hash App
Mobile application · iOSOn the Hash App is a social and content-focused mobile application built around community interaction, requiring a visual design that could balance modern aesthetics with practical usability across a complex feature set.
The problem
The primary challenge was balancing innovative visual design with practical usability. The interface needed to feel modern and engaging while remaining intuitive and consistent across platforms. Integrating user feedback, maintaining design coherence, and validating decisions through usability testing created significant design complexity.
What we delivered
A user-centered iOS UI design approach applied throughout. User behavior research, user interface guidelines and best practices for clarity and consistency, innovative user interface elements, and a complete design system that the development team could build from and extend over time.
The outcome
- Visually appealing and intuitive interface that received strong positive feedback from users
- Engagement and interaction with app features increased, contributing to long-term user satisfaction and retention
- Consistent design system improved maintainability and brand cohesion across all future updates
- Enhanced user interface strengthened the app's reputation and competitive position in its category
Three things most iPhone app design services do not do
01
Design to Apple's Human Interface Guidelines, not around them
Most iPhone app design services apply a visual style on top of a generic mobile layout. The result is an app that looks impressive in mockups but fails App Store review or gets flagged during the Apple design review for HIG violations. We design with HIG as the foundation, not a constraint to work around. Safe area insets, Dynamic Type, tap target sizing, and system font usage are applied from screen one.
HIG rule
Minimum 44px tap targets
Applied to every interactive element by default
HIG rule
Dynamic Type scaling
All text scales without breaking layouts
HIG rule
Safe area compliance
Content never overlaps notch or home indicator
02
Every screen ships with a Figma auto-layout component your developer can build from immediately
Many iOS app UI design deliverables are Figma files where every screen is a static frame with no component system. Your developer has to infer what the button does in its disabled state, what the input looks like with an error, and how the card adapts to longer text. We build a component library alongside the screens so none of those questions exist at handoff.
What you receive from other agencies
Static frames with no variants or states
Developer spends hours interpreting what to build
Edge cases discovered in production, not design
What you receive from Redefine
Auto-layout components with every state and variant
Developer opens the file and has zero questions
Edge cases designed and documented before code is written
03
We prototype and test in Figma before any pixel goes to code
Every iOS design project ships with an interactive Figma prototype that covers all primary flows. You can tap through the entire app experience before your developer writes a single line of Swift. Misaligned navigation, unclear gestures, and confusing onboarding patterns are caught here, where fixing them costs zero developer hours. Not in Sprint 3 when the product is already half-built.
Questions buyers ask about iOS design services
This engagement covers iOS-specific design following Apple's Human Interface Guidelines. Android and Material Design are separate engagements with different component systems, navigation patterns, and platform conventions. If you need both, we scope them as two separate projects to ensure neither platform gets a generic cross-platform treatment. Submit a brief and specify which platform or platforms you need.
The Figma handoff includes: the complete component library with every state and variant using auto-layout, high-fidelity screens for all primary flows, an interactive prototype connecting all flows, spacing and color tokens named for development use, and export settings pre-configured for iOS resolution. Your developer opens one file and has every asset, measurement, and specification they need.
A standard iOS app design engagement with discovery, wireframes, high-fidelity user interface, prototype, and handoff runs 6 weeks. A focused engagement covering only specific flows or screens runs 3 to 4 weeks. A redesign of an existing app where research is already available can run faster. Timeline is agreed in the proposal before Sprint 1. It does not change without a written scope amendment.
Yes. The App Store asset kit is included in a full iOS design engagement: app icon at 1024x1024 and all required sizes, screenshots at the required device dimensions (6.7 inch iPhone required, plus iPad if your app supports it), and preview screen copy formatted to Apple's current submission requirements.
Yes. A redesign brief starts with a user experience audit of the existing app to identify which flows to preserve and which to rethink. This replaces the discovery and research phase with a more targeted audit process. Bring your existing Figma files or TestFlight build and we scope from there.
