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.

I’ve always been frustrated with the GO website, your app is already easier to use!" -Michael "Your app is awesome. A fantastic idea. It shows how to use technology to improve our lives." -Miguel USAGE TIPS ● Tap on the "From"/"Travel to" table cells to set your trip departure/arrival. ● In the trips view, use the icon in the upper-right corner to switch between details and overview mode. ● Use the "Info" button at the top-right of the Search screen to get explanations on the schedules. SUPPORT Send any problems via e-mail to [email protected] ● If you experience crashing when starting up after an upgrade, delete the app and download again (free of charge) from the App Store. ● To get the latest schedule, connect to the Internet first, then launch GOToronto and go to the Schedule screen.

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.
