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.

Colorever: a relaxing gem sorting puzzle where every tap reveals sparkling pixel art. Tap a gem and watch its whole cluster glide home, one shining piece at a time, until a bright gem art picture is complete. No timers. No energy system. No fail screens. Just you, the gems, and a calm little puzzle you can always solve. HOW TO PLAY • Tap a gem, move a cluster. Every connected gem of the same color is picked up together, then flies to its matching space one by one. • Read the board. Each space shows the color of the gem it is waiting for. Match gem to space and it locks in with a satisfying click. • Use the tray. Two roomy rows hold the gems you are not ready to place yet, so sorting stays strategic, never frustrating. • Reveal the picture. Place the last gem and watch the full pixel art scene light up, saved forever in your gallery. WHY PLAYERS LOVE IT • Genuinely relaxing. No countdowns, no energy system, no pressure. Play one puzzle on a coffee break or twenty in a row. • Satisfying gem sorting. Move the colors around, organize the design, and watch order emerge one gem at a time. • Always solvable. Every level has a solution, so getting stuck is temporary, never fatal. • Gentle learning curve. The first puzzles teach themselves. Later boards are wide, layered and worth real thought. • Handy helpers. Extra tray space, undo, hints, and a smart tap that tidies up the easy gems for you. • Made to feel good. Crisp gems, glowing diamonds, soft sound and gentle haptics on every placement. • Play offline, anywhere. No connection needed. Pause mid-puzzle and pick up hours later, exactly where you left it. A GROWING GEM GALLERY Hundreds of pixel art pictures to complete — animals, food, flowers, cities and cozy little scenes — with fresh sets added regularly. Every finished picture joins your gallery, so your gem art collection keeps growing as you play. FOR FANS OF Gem sorting and color sort puzzles. Pixel art and coloring games. Diamond art and diamond painting. Zen brain games and calm logic puzzles. And if you love color by number, Colorever is a fresh twist on the same relaxing feeling. Take a breath. Tap a gem. Let the art shine.

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.
