Hire App Designers - Mobile & Web Application UI/UX

Kultrix app designers work across iOS apps, Android apps, React Native cross-platform apps, and complex web applications. We have experience in consumer apps, B2B SaaS tools, fintech, health tech, marketplace apps, and productivity tools. We match each engagement with a designer whose portfolio includes your specific app category.

Yes. Our mobile app designers follow Apple Human Interface Guidelines and Material Design 3 guidelines closely - not just stylistically but functionally. This means correct navigation patterns, gesture conventions, touch target sizing, safe area handling, and platform-appropriate feedback patterns. Users notice when an app breaks these conventions, even if they cannot articulate why.

Yes. We design for both platforms, either as a unified cross-platform design system or as separate platform-native designs depending on your engineering approach. For React Native apps, we typically design one system with platform-specific adaptations. For separate native apps, we design each platform independently to honor its conventions.

We design onboarding with a single goal: get the user to the first value moment as quickly as possible. This means removing unnecessary steps, deferring optional information collection, and using progressive disclosure. We test onboarding prototypes with real users to measure completion rate and identify drop-off points before finalizing.

Yes. User research is built into every Kultrix app design engagement, not billed as a separate optional phase. Our designers conduct user interviews, run usability tests on prototypes, analyze behavioral data, and review app store feedback. Decisions are documented with the research evidence that supports them.

Dark mode is designed as a first-class variant in the Figma component library, not adapted from light mode colors. We use semantic color tokens (background, surface, on-surface, etc.) so switching between modes is systematic. Every component is tested in both modes before handoff.

We prototype in Figma for straightforward flows and use Protopie for complex interactions that require variables, conditionals, and sensor inputs (like swipe gestures and animations). The right tool depends on what needs to be validated - we match the prototype fidelity to the question being tested.

Yes. App redesigns are common engagements. We start with a UX audit of the existing app - reviewing app store reviews, session recordings if available, and conducting user interviews - to identify pain points with evidence. This prevents redesigns that improve appearance but break familiar patterns that existing users rely on.

Our designers produce component-based Figma files with named layers, auto layout, complete state coverage (default, hover, pressed, disabled, error), and explicit spacing values. They annotate custom interactions, transitions, and edge cases. They stay available during development to answer questions and review implementations before release.

An MVP app design covering core flows typically takes four to six weeks from discovery to developer handoff. A full design system with all screens and states takes six to ten weeks. Redesign projects with research and testing take similar timelines. We provide a phased plan with weekly milestones after the first call.

Most app designer engagements begin within one to two weeks. We shortlist candidates based on your app category and platform, arrange a portfolio review with you, and start onboarding immediately after you confirm. Most clients see research findings or wireframes within the first week.

You own all design output - Figma files, prototypes, exported assets, and research documentation. We transfer Figma file ownership to your team at the end of every engagement with no restrictions on use. Your developers and future designers can work from the files freely.
