Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Plan your carpet tile layout before you buy — right on your phone. TileGrid lets you design room layouts using carpet tiles from 25cm to 50cm, mixing colors and shapes to create stunning floor patterns. Choose from 5 brands and 900+ real tile colors, or import your own. Whether you're renovating a home office or designing a retail space, TileGrid helps you visualize the result and calculate the exact number of tiles to order. BRANDS & COLORS - Toli — 145 colors across 14 series (AK10, AK11, AK27, AK35, FF21, FF24, FF42, FF45, FF70, AK80, AK95, NP4, GA-400, GA-400A) plus 5 character/special-edition lines (Anpanman, Anpanman Number, Dick Bruna/Miffy, Hello Kitty, Kids Road) - FLOR — 723 colorways across 183 Flor designs at 50cm, including the Trina Turk, Arras, Get The Look, and Carbon Negative collections - SANKO — 33 colors in 25cm, 30cm, and 45cm sizes (solid & pattern) - SankoPet — 13 pet-friendly colors in 30cm - Common Ground (块块与共) — 呼乎 & 四时 series (15 colors) - My Colors — Import your own tile photos from your camera roll TILE SIZES - 25cm, 30cm, 40cm, 45cm, 50cm — choose the right size for your project KEY FEATURES - Paint Mode — Tap to fill tiles with colors from real product catalogs - Pattern Templates — Pick from a curated gallery of pre-designed room patterns; layout paints itself, then swap palettes to dial it in - Texture Rotate — Rotate tile textures 0°/90°/180°/270° for directional patterns - Triangle Tiles — Split any tile diagonally to create two-tone patterns - Half Tiles — Split any tile horizontally or vertically into two color regions - Fan (Quarter-Circle) Tiles — Add curved accents with arc and remainder shapes - No-Tile Zones — Mark areas where tiles won't be placed (under furniture, columns, etc.) - Share Cards — Share branded layout cards with project name and tile count - Preview Mode — See your finished design without the grid lines, and save the image - Order Summary — Get an exact tile count per color and brand, with smart bin-packing for edge cuts - Grid Alignment — Drag to adjust where cut tiles fall on room edges. Snap to center with one tap - Undo/Redo — Full history so you can experiment freely - Multiple Rooms — Manage separate layouts for each room in your project - Duplicate Rooms — Copy an existing layout as a starting point for variations SMART TILE COUNTING TileGrid doesn't just count grid cells — it calculates the actual number of tiles you need to purchase: - Edge tiles are packed efficiently using bin-packing algorithms - Same-color fan arc + remainder = 1 tile (no waste) - Triangle halves pair up across your layout - Each color is calculated independently GETTING STARTED Open the app and tap "Try Sample" to explore a pre-built room design, or tap "New Room" to start from scratch. Enter your room dimensions in meters, pick your tile size, and start painting.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
