Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
Purple is social designed for real life. We built Purple to help people spend less time scrolling and more time actually showing up. Whether you are discovering what is happening nearby, sharing a Moment, gathering your friends, or hosting something of your own, Purple makes it easier to turn online connections into real world experiences. Discover What's Happening Explore events happening around you, from small gatherings to larger community experiences. No endless feeds. No noise. Just what is relevant, nearby, and worth showing up for. Share Moments Moments let you capture and share what is happening in real time. Post updates, highlight experiences, and give people a glimpse of what they are missing without turning it into a performance. Moments are built to reflect real life, not curated perfection. Join Circles Circles are private groups for friends, communities, and shared interests. They are built for intentional connection, not broadcasting. Create one, get invited, and keep things personal. Host With Purpose Planning something? Purple gives hosts simple tools to share events, invite people, and bring the right crowd together, whether it is a casual meetup, a creative event, or something bigger. Built For Intentional Social Purple is not about likes or clout. It is about: • Real people • Real plans • Real experiences We believe the best moments do not live on a screen. They happen when people actually show up. Why Purple • Discover events without the noise • Share real time Moments • Create or join private Circles • Meet people in real life, not just online • Designed for community, not consumption Purple is currently evolving, and we are building alongside our community. Early users help shape what comes next. Download Purple and start showing up.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
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.
