Design a light-mode mobile app interface screen: quiet editorial discipline meets high-performance biometric tracking with soft natural geometry.
LAYOUT
The mobile screen follows an intuitive top-to-bottom rhythm: status bar directly into a generous greeting header featuring an offset streak badge. Below lies an edge-bleeding horizontal carousel of category cards, followed by stacked modular analytical widgets: first the four-column weekly metrics, followed by 'Today\'s Plan' with radial completion and thumbnail preview.
PALETTE (use these exact hex values)
- #F8F9FA — Canvas Background: Full screen base layer providing a gentle, low-contrast foundation below white modules
- #FFFFFF — Surface Card: Background for all elevated interactive cards, metric modules, and sub-panels
- #234338 — Evergreen Accent: Primary focal color for the daily streak bubble and key progress indicators
- #4E937A — Run Sage: Sport tag and category icon background for running, walking, and endurance tasks
- #4B8E6D — Train Jade: Category icon circle for strength training and gym equipment routines
- #68B0C8 — Swim Cyan: Category icon circle for pool, open water, and recovery activities
- #E8A28E — Fight Terracotta: Category icon circle for combat sports and high-intensity interval training
- #E5855A — Calorie Flame: Dedicated accent color for active caloric burn metrics and flame glyphs
- #111827 — Obsidian Text: Primary headings, category titles, metric numerals, and high-emphasis labels
- #71767B — Slate Text: Subtitles, descriptor labels, metric units, and passive button text
TYPOGRAPHY
Typeface SF Pro Display (or Inter, Plus Jakarta Sans, Public Sans), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 14px body, 16px body-lg, 18px subheading, 20px heading, 28px display. Tracking -0.02em for headings, 0 for body text. The type choice is restrained, confident, and athletic without feeling aggressive or industrial. Tight letter spacing on large display headings creates an editorial magazine atmosphere, while generously spaced small captions guarantee quick glanceability during movement. Premium sans-serifs like SF Pro or Inter reinforce technical accuracy and serene focus.
GEOMETRY & SPACING
Corner radii — cards 24px, links 999px, inputs 12px, buttons 999px. Spacing on a 4px unit, 12px gaps, 24px between sections, 390px container, comfortable density.
DEPTH
Depth is handled through surface tonal variation and almost invisible diffusion rather than pronounced drop shadows. Pure white cards (#FFFFFF) sit directly over the subtle off-white background (#F8F9FA) with a soft ambient blur (0px 4px 16px rgba(0, 0, 0, 0.03)). Zero stroked borders are used on core cards, preserving an organic, paper-like aesthetic.
IMAGERY
Photography emphasizes natural athleticism, motion, and raw focus in authentic environments (outdoor coastal running, atmospheric gym lighting, indoor lap pools). Subjects are depicted mid-motion with natural skin tones and minimal artificial grading. Studio product cutouts or overly posed fitness modeling are strictly off-brand.
SIGNATURE DETAIL — the thing that makes this design itself
The overlapping circular icon anchor: each carousel card features a sport-specific tinted circle that straddles the precise horizontal boundary between raw photography and the clean white typographic card base. This grounding element acts as both a category signature and an visual bridge between visceral imagery and structured data.
MUST
- Use 24px border radii consistently across major module containers and cards.
- Overlap category icon badges across the seam separating photograph and card body by exactly 50%.
- Keep background canvas at #F8F9FA to allow pure white cards to separate naturally without borders.
- Limit bold color usage to functional signifiers: streaks, categories, and progress rings.
AVOID
- Never apply harsh black borders or heavy drop shadows; depth is strictly atmospheric and soft.
- Do not use saturated primary neon colors; keep tones organic, earthy, and mineral-derived.
- Never square off corners on cards, badges, or circular navigation affordances.
- Avoid crowded card headers; leave ample vertical clearance (minimum 16px) around titles.
