Gamified App Skill
Produce a multi-screen mobile prototype on a single dark showcase page. Three phone frames side-by-side, each one its own moment in the journey.
Workflow
- Read the active DESIGN.md (injected above). For gamified apps, lean on bold display type for headlines and a brighter, broader palette than most products — quests look like quests because the colors do.
- Pick the brand + value prop from the brief. Generate real quest names (e.g. "Body — 20-min strength: pushups & planks", "Read — Four Thousand Weeks", "Listen — Huberman Lab · Sleep Architecture", "Nourish — Cook a high-protein lunch", "Mind — 10-min focus meditation", "Watch — The Bear · S3 E4").
- Stage — full-bleed dark page (near-black
#0e0d0cor DS dark token) with a soft top spotlight gradient. Above the phones, a small caption row: "HI-FI PROTOTYPE · IPHONE" left, brand wordmark right, both in mono. - Phones — three 360×780 phone frames in a horizontal row (wraps to stack on narrow viewports). Each phone:
- 12px black bezel, 44px corner radius, dynamic-island notch. - Status bar (time / signal / battery). - Phone-specific content (below). - Bottom tab bar with 5 icons (Today, Library, Stats, ⊕ central CTA, Profile). Active tab in accent.
- Phone 1 — cover poster (sales/value prop):
- Status bar. - HI-FI PROTOTYPE · IPHONE eyebrow. - Big display headline ("Daily quests for becoming a better human."), accent on "becoming". - 1–2 sentence body in muted serif/sans. - Mono tip line ("Tap quests to open detail. Toggle [theme] in the toolbar to switch theme & layout.") - Subtle scrolling teaser of the next screen at the bottom edge.
- Phone 2 — today's quests dashboard (the hero screen):
- Greeting "Good morning, Sam" + small XP-bell ringing. - Level ribbon — "LV 14 · Level 14 · 1648 / 2480 XP" with a progress bar inside a glassmorphic ribbon. - Sub-line: "8 quests waiting · earn 430 XP today". - 3×2 grid of quest tiles. Each tile: rounded corner, pastel accent color, glyph chip in top-left, title, mini-meta line, "+NN XP" pill in bottom-right. - Bottom tab bar.
- Phone 3 — quest detail:
- Back arrow + screen title ("Quest"). - Hero block with the quest's accent color, big serif quest title ("Body — strength"), short narrative body, "REWARD +90 XP" stamp. - Steps checklist (3–4 micro-tasks, one done, two pending). - Big primary CTA "Start quest" pill at the bottom in accent.
- Write a single HTML document:
- <!doctype html> through </html>, CSS inline. - All in CSS — no images. Use linear-gradient and inline SVG glyphs for tile chips and tab icons. - data-od-id on stage, each phone, each frame's regions.
- Self-check:
- Three frames, each with a distinct purpose. Not three copies of the same screen. - Tile colors don't overpower — each quest tile uses a different pastel against the same neutral surface. - Reads as gamified and adult — playful, not childish.
