A product spec, screen plans, and build steps for your coding agent.

Your first Build Kit is free with a verified email.
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.

"My son loves Touch and Write - Fantastic app and the customising options are great!" - from parent review ***** "Love, love, love your app Touch and Write:)" - from parent review ***** "Touch and Write has moved to the top of my list for learning to write. It's extremely fun for my 4 year old with classic autism and the easiest app for me to customize!" - from parent review ***** "I would highly highly highly recommend this app" - WelcomeToTheirWorld app reviews ***** "I have recommended Touch and Write to all my colleagues and parents. I think it is fabulous! My students do not get frustrated and quit. They are able to focus for extended periods of time and I get to make my own target list. Thanks for this great app." - Speech Therapist in California ***** "I just wanted to tell you about my session with my student today using 'Touch and Write.' He is a kindergarten student... he resists writing and acts out to avoid it. Today I showed him the 'Touch and Write' program... he was totally attentive for 30 minutes, quickly learned to move between the different writing textures and understood the use of the 'little monster' to make the letter correctly." – Teacher ***** "The k and 1st grade kids are really engaged! One of them worked for 15 minutes - the most we have seen him do in weeks." - Teacher FizzBrain featured on CBS's "60 Minutes"! Kids love learning to write - especially when they can use shaving cream, paint, and jello!

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.
Not assessed in a Build Kit yet.
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.
