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
MAKE YOUR MOVE Bumble is the women-first dating app designed to create safer, more respectful connections and conversations that lead to better in-person dates and relationships. HOW WE SUPPORT YOUR DATING JOURNEY We empower you to show up as your most authentic self, so you can move confidently toward meeting in real life by: - Focusing on you as a person, not a profile. When you write your bio and prompts, or update your photos, we’ll share personalized tips that help highlight the unique qualities that make you stand out. - Showing you people who match your energy. Just set your Intentions and Looking For to find people who want to date the way you do. Or, add Interest Badges to find people who are into what you’re into. - Empowering women to message first. Once a match is made, women send the first chat, and their match has 24 hours to reply before the connection expires. - Prioritizing safety at every step of your dating journey. Get ID Verified early-on (like the majority of our community), try Share Date to drop location details with the group chat, or use Block and Report, Unmatch, or the Safety Center for extra support. - Giving your chats a boost. Our built-in guidance helps keep your exchanges kind and respectful, while chat and video options make it easier to progress your connection, without ever leaving the app. - Adapting to your needs. If you want to take a step back from meeting new people, enable Snooze Mode to take a break from dating without losing your current matches. Looking for even more options? Try Bumble Boost, Bumble Premium, and Premium+. Bumble is free, but these premium services give you even more flexibility and dating options, with advanced filters, extended matches, Incognito Mode, and Travel Mode. ADDITIONAL INFO Your personal data is securely processed in line with our privacy policy and applicable laws.

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.
