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
After a cue-sport session, the useful details disappear quickly: one clean safety, one loose frame, one drill worth repeating. Evanora keeps that work together with Frame Board scoring, Drill Plans, Cue Memory Drill, Session Feed posts, and an AI guide for cue-sport review prompts. Use Frame Board to start a set, track every frame, and reopen saved scorecards when you want to continue or study a result. Build Drill Plans for upcoming table work, record the real finish time for each block, and keep a readable practice trail that stays close to your match history. Cue Memory Drill adds a short color-order exercise you can run between longer sessions when you want to sharpen recall and table focus. Evanora also gives you a profile space for your nickname and avatar, a Session Feed for posting table notes, photos, and clips, and reporting or blocking tools to help manage what you see there. The AI guide is available after you review the in-app notice explaining what data is needed to answer your request. Coin Packs are offered as in-app purchases and are used by guided features inside Evanora.

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.

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.
