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
iClassics: Beyond Engrossing iClassics unites the old and the new to create immersive experiences that inspire and move everyone. iClassics Productions is now famous for creating Immersive Entertainment apps focused on the horror and terror genres. And so how wrong would it be if we failed to include the classic and quintessentially American tale, The Legend of Sleepy Hollow. In this innovative and feature-length Immersive Entertainment app, Washington Irving's magnum opus is lovingly and artistically enhanced with interaction, illustration, animation, FX, and OST. Being one of our latest releases, the animation is richer and more cinematic than ever, complete with a masterful soundtrack composed by Miquel Tejada and Adri Menathat, which serves to make the visual details all the more sublime. By casting a modern glare on this ludic horror tale, the result is a spectacular and wholly original experience that utilizes every feature of modern mobile devices (gyro-perspective, flash, vibration). TILT to see more TOUCH to transform TURN to discover what's in the shadows ▶ APP FEATURES: Main features: Available in 3 languages: English, Spanish and French 86 sound effects 53 minute soundtrack 52 illustrations 67 animations 50 interactive scenes Extras: Washington Irving biography and Aitor Prieto sketchbook - Jump to any page in the book with the table of contents. - Memory pages: Put it down at any time and return to the same page. - Universal App: Pay once and access from any iPhone or iPad device. - Easy to use interface With the lovingly constructed enhancements for which iClassics Productions has become famous, this chilling and family-friendly Immersive Entertainment app will have you believing that the headless horseman is galloping out of your device's screen. ▶ The iClassics Collection: The iClassics are interactive experiences based on classics of literature from all times and genres: E.A.

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.
