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.

WatcheePro is a comprehensive app for watch collectors and enthusiasts that tracks watch collection information. STORE WATCH DETAILS Set watch details including category, origin (country flags), status, dimensions, serial and reference numbers, materials, movement, complications (up to six), pricing, and much more. CUSTOMIZABLE WATCH PLATES Change colors of plate, crown, info frame, and font independently to match watch design characteristics. Animated crown, pusher, and gears show watch info. TRACK WATCH STATISTICS Track watch collection statistics such as wear rates, accuracy measurements, service history, and compare individual watch specs to your watch collection averages. View a summary of your entire collection. WEAR HISTORY Wear history can be examined per watch or for the whole collection. You can filter the wears by day of the week to easily check which watches you tend to wear on sundays as an example. ACCURACY MEASUREMENT Store multiple accuracy measurements for each watch. Check interim result for a measurement while test is active. Storing the results of each test allows you to compare whether a watch is more accurate on your wrist than in a box or on a winder, for example. If you enable the "Highlight special watches" flip in the settings, then the top-3 most accurate watches will automatically get a special plate design to highlight it. It can be quite fun to see which watches make it to the top-3 and when a watch gets removed from it. TIMEGRAPHER ACCURACY MEASUREMENTS Store results of timegrapher measurements including rate, beat error and amplitude in six positions. WatcheePro automatically calculates averages and deltas based on rate, beat error, and amplitude. Fully-wound and 24-hours running can be compared. WEAR RATES Track which watches you wear most often, how many days since last wear, and cost per wear. Watch statistics are just a tap away. Wear rates can be examined for the whole watch collection and we've also added the per watch effective wear rate, which automatically calculates a percentage for each watch regarding how many times it has been worn compared to the days it has been owned. Wear rates are also available for brands and manufacturing countries, so you can find out how much you wear your watches belonging to a certain brand or watches made in a certain country vs. all other watches. If you enable the "Highlight special watches" flip in the settings, then the most/least worn watches will automatically get a special plate design to highlight it. USEFUL AND ENTERTAINING Export your collection to a spreadsheet. Create PDFs of your watches for insurance or selling purposes. Earn badges for entering watch info and for wear counts. Can't decide what to wear, let WatcheePro pick! HISTORY LOG If enabled in the settings, log actions regarding watches such as when a watch is added to the collection or sold. KEEPER RATE AND SELLER RATE WatcheePro tracks Keeper & Seller rates for your watches by comparing a specific watch against the other watches in your collection. WatcheePro compares the characteristics of your watch against the averages across your collection. WATCH COLLECTION SUMMARY DETAILS Number of watches in collection, number of sold watches, total cost of watches in collection, total retail cost of watches in collection, total cost of sold watches, profit from sold watches, results of watch deals, average diameter, average thickness, average lug-to-lug, and total weight. APP DEVELOPMENT WatcheePro stores all data on your device and does not need an internet connection. The app is developed by two watch enthusiasts and programmers. WatcheePro is regularly updated with new features and we welcome feedback. DEVELOPERS WatcheePro is developed by Anssi Hakkarainen and Brian Hall. Anssi is a database developer, lifetime programmer, and watch enthusiast. Brian is a computer science professor, engineer, and watchmaker.

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.
