Health & Fitness Progress Tracker UI

I’m building a cross-platform health and fitness app whose single purpose is to let users record every workout, visualise their progress, and feel motivated to keep going. I already have the core feature set mapped out; what I need now is a thoughtful UI/UX flow that makes logging reps, sets, cardio sessions and personal records feel effortless on both iOS and Android. Here’s how I see the design journey: • Discovery & mood-boarding based on a few reference apps I’ll share. • Low-fidelity wireframes that nail the navigation logic, including onboarding, workout entry, history, and progress dashboards. • High-fidelity screens in a modern, energetic style that still meets both Apple Human Interface Guidelines and Material Design. • A clickable prototype (Figma preferred) so I can run quick user tests. • Final export of all assets, typography and colour variables organised in a reusable design system. Acceptance criteria – Smooth two-tap flow from home screen to workout logged. – Clear progress visualisations (charts, badges, streak counters) readable on small and large phones. – Consistent behaviour and component naming between iOS and Android files. If you’ve worked on fitness or data-heavy apps before and know how to keep the interface light, intuitive and on-brand, I’d love to see your approach and a couple of case studies.
