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.

After a stroke, sight can change in ways that are hard to live with: words slipping off the page, things missed on one side, the world feeling somehow incomplete. Stroke Sight is a simple, daily way to train your vision at home, at your own pace. It's built around nine exercises for the four most common visual changes after stroke (hemianopia, quadrantanopia, visual neglect and scotoma), based on the compensatory scanning and tracking approach used in stroke rehabilitation research. Why we built it Stroke Sight was made by a family living with stroke. After someone we love lost a large part of their visual field, we couldn't find an app that was thorough, calm to use, and available in our own language, so we built one. It's made in the UK, for survivors and the people who care for them. What you can practise • Field loss (hemianopia and quadrantanopia): practise scanning into the side you've lost, with guided exercises for noticing your surroundings and for reading. • Neglect (one-sided inattention): gentle tracking toward the side that gets overlooked, a widely used approach in stroke rehabilitation. • Scotoma (a blind spot): training to find the edges of the gap and work around it. The exercises use the kinds of scanning and tracking practice described in published stroke-rehabilitation research. What's included • Nine exercises, each with ten levels that adapt as you improve • Three colour modes (standard, high-contrast yellow and high-contrast white) for changed colour vision • Full left- and right-side support throughout • A one-tap progress report (PDF) you can email straight to your therapist or orthoptist, so they can see how you're getting on between appointments • Practise in your own language: 20 of them, including the first vision-rehab exercises in Welsh and Twi • Adjustable spatial audio (off, subtle or prominent) for sound sensitivity or hyperacusis • Works on iPhone and iPad In 20 languages Real, language-specific content, not machine-translated menus. English, Welsh, Irish (Gaeilge), Spanish, Latin American Spanish, French, Canadian French, German, Italian, Portuguese, Brazilian Portuguese, Polish, Japanese, Korean, Hindi, Arabic, Chinese, Twi, Danish and Dutch.

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.

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.
