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.

*** Featured as "App of the Day" on the App Store! *** Thinkrolls Space is a child-friendly puzzle game that’s out of this world. Colorful heroes boldly roll where no Thinkroll has rolled before, in over 200 mazes set across seven unique planets. A cast of oddball aliens will make you grin from ear to ear. But you’ll need brains and nimble fingers to reach your goal—and catch the waiting UFO that will beam your Thinkroll to the next fun-filled planet. CLOSE ENCOUNTERS Thinkrolls and Thinkrolls 2 introduced our revolving heroes. Thinkrolls: Kings & Queens added exciting new concepts—and dragons. Now Thinkrolls Space blasts the award-winning series into outer space. You’ll meet goo monsters, bleeping robots, spring-like soprano aliens, and cheese monsters who love munching moon cheese. You’ll face vanishing rainbow bridges, plasma fields, teleporters—and more. Each of these can help or hinder. You must figure out which—and how to move and match objects to clear a path, get the key, and open a gate to the next level. REACH FOR THE STARS Two difficulty modes and unlimited penalty-free retries ensure the 200+ level journey is stress-free for children and adults alike. Along the way, stars and hearts can be collected, and later used to unlock 24 unique alien Thinkrolls. Throughout, players are encouraged to experiment. They will learn through trial and error to combine elements, and build on successive lessons to strengthen creative thinking, logic, problem solving, spatial cognition, and memory. Don’t be surprised when even younger players start thinking several moves ahead, in this fun, inventive, family-friendly combination of physics problems, logic puzzles, and exciting platform gaming!

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.
