Teen Learning App UI Design

I’m turning a learning-app concept for teenagers into a polished mobile experience and need a designer who can own the complete UI journey. The flow is already sketched on paper; what’s missing is a visually engaging design that feels fresh and relatable to a 13-19 audience without drifting into anything too childish.

Here’s what I’m looking for:

• High-fidelity screens for the core user journey (welcome, onboarding, lesson overview, interactive lesson, progress tracker, profile and settings).
• A clickable prototype in Figma, Sketch or Adobe XD so I can test the experience on both iOS and Android.
• A small, clearly documented style guide covering colour palette, typography and iconography to keep future screens consistent.

Acceptance criteria
1. Every screen must scale cleanly to the most common phone resolutions (iPhone 13 / Pixel 7 as baseline).
2. Colour contrast and tap-target sizes should meet WCAG AA guidelines.
3. Prototype handed over with organised layers and reusable components.

I’ll share brand colours, mood-board references and the draft wireframes as soon as we start. Turnaround is flexible within two weeks; quality is my priority. If you have a portfolio featuring youth-oriented apps, that would be the perfect starting point for our conversation.
