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.

** Kirkus Reviews - Kirkus Star ** Children's Technology Review Editor's Choice ** Common Sense Media - 5 Stars ** Parents' Choice Awards Recommended ** Apple New and Noteworthy JUST MOO IT! Sandra Boynton’s best-selling book of all time comes alive with sound and movement and gloriously unpredictable interactivity. The wryly inventive Moo, Baa, La La La! digital book app will intrigue and amuse little kids and big people alike, and perhaps even elicit an appreciative snort from the occasional uninvited rhinoceros. “This is my second digital book project with the perfectly wonderful team at Loud Crow,” says Sandra Boynton, “and I’m really happy with what we’ve created together. As with The Going to Bed Book, our interactive book app version of Moo, Baa, La La La! succeeds in retaining the original board book experience, while adding multi-sensory dimension. It’s such a cool enterprise.” Far beyond any e-book experience, the Moo, Baa, La La La! interactive book app has all the magic and appeal of a traditional pop-up book, offering lively interactivity and nifty discovery. Of course you can hear each animal make its unique sound. (In some cases, VERY unique.) But there’s more! Help the perplexed chicken stagehand raise the curtain on a stageful of dapper dancing pigs. Turn day to night with the touch of the moon. Slingshot the running cats away from the barking dogs. A touch of the duck activates a quack which brings in another duck. And another. And another. Even the back cover has a curiously articulate spokesman that you really mustn’t miss. Features: * The second Boynton Moo Media book app (following their top-selling debut, The Going To Bed Book app), venturing far beyond what an e-book experience can offer * Touch the animals to hear them moo or oink or quack or even, in the case of three incongruous showbiz pigs, harmonize * Boynton has redrawn and recolored the original illustrations for her most popular book ever, Moo, Baa, La La La! (over 5 million in print!) * Includes an original instrumental soundtrack, "Country Air"; a wonderful uptempo pastoral string quartet written by Michael Ford * Realistic page turning interactions just like the original board book * "The Big Guy Reads It"; with word highlighting to help improve reading skills * Or “I want to read it myself” and hear individual words pronounced with the tap of a finger Visit us: www.loudcrow.com Follow us: twitter.com/loudcrowinc Like us: facebook.com/loudcrow

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.
