Sleep Tracker UI/UX Design

I’m building a dedicated sleep-tracking mobile app and need a polished UI/UX that feels calm, intuitive, and data-driven. The single, must-have feature is Sleep cycle analysis, and all insights will be visualised through engaging graphs and charts—no tables or walls of text.

Here’s what I’d like from you:
• A full set of high-fidelity screens that cover onboarding, nightly tracking, the main dashboard with cycle graphs, and a history area for deeper dives.
• A sleek dark theme by default, with colour accents
• Interactive chart components ready for implementation (think expandable bars, pinch-to-zoom line graphs).
• A Figma file (or Sketch/Adobe XD if you prefer) with organised layers, reusable components, and text styles for easy hand-off to developers.
