Design Beautiful Apps That Users Love

Mobile app UI design covers the visual and interactive design of every screen in your app — including user research, wireframes, high-fidelity UI mockups, design system / component library, interactive prototypes, usability testing, and developer-ready handoff files. At Qubixel Technologies, our end-to-end service handles all of these elements within a single integrated engagement.

A typical mobile app UI design engagement at Qubixel Technologies ranges from 4 to 12 weeks depending on the project scope, number of screens, and complexity of interactions. A focused MVP design (20–40 screens) typically takes 4–6 weeks, while a comprehensive enterprise application with 80–120 screens and a full design system takes 8–12 weeks. We will provide a detailed timeline estimate during our initial discovery call.

Yes. We design fully platform-adapted interfaces for both iOS (following Apple Human Interface Guidelines) and Android (following Material Design 3), ensuring native-quality experiences on both platforms. We can deliver designs for a single platform or both simultaneously, depending on your roadmap — with consistent brand language expressed through platform-appropriate interaction patterns on each.

Our designers work primarily in Figma as the core design and collaboration tool, with support for Adobe XD on legacy projects. We use ProtoPie for advanced interactive prototyping beyond Figma's native capabilities, Zeplin for structured developer handoff, Maze for remote usability testing, and Lottie/Rive for micro-animation specifications. All deliverables are shared via collaborative cloud workspaces so your team has real-time visibility throughout the project.

Absolutely. Every project concludes with a complete, fully annotated design system and developer-ready handoff package — including spacing specifications, color tokens, component documentation, responsive behavior notes, and all exportable assets in required formats. Our team also offers a one-week post-handoff support window to address any technical questions from your development team during implementation.

Yes. App redesign is one of our most requested services. We begin with a structured UX audit of your existing product — systematically identifying friction points, usability issues, accessibility failures, and design inconsistencies. We then produce a prioritized redesign roadmap and can execute the redesign in full or in phased releases based on your capacity for engineering changes.

During discovery, we conduct a brand alignment workshop to understand your visual identity, brand values, and target audience. If you have an existing brand guide, we design within it. If not, we can develop a mobile-specific design language from scratch. Before proceeding to full UI production, we present visual direction concepts — mood boards, color palettes, and typography pairings — for your approval, ensuring complete alignment before any screen-level work begins.

Yes. We offer flexible ongoing design retainer arrangements for clients who need a dedicated design partner beyond the initial project. Our retainer service covers new feature design, design system expansion, A/B test variant creation, and post-launch UX iteration based on real user data. Many of our clients transition from project engagements to long-term retainers as their products scale.
