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.

Original App Store material. Ratings and screenshots describe the existing app, not proof of demand for your version.
Some places stay with you. The little restaurant down a side street. The bar where you lost track of time. The view you promised yourself you'd see again. Come Back One Day is a personal map of those places. Save where you've been, why it mattered, and everything you need to find your way back. SAVE THE PLACES THAT MATTER Drop a pin on any restaurant, bar or pub, hotel, food market, or spot worth remembering. Search for a place by name and the address fills in automatically, or simply use your current location. REMEMBER THE DETAILS Add photos, a star rating, the date you visited, and notes about what made it special. Save the venue's website so booking your next visit is one tap away. YOUR PHOTOS, YOUR MAP Every place is pinned to the map with your own photo, so your travels become something you can actually see. Add as many photos as you like, reorder them, and choose which one becomes the cover shot. CAPTURE IT IN THE MOMENT Use Quick Camera to snap a photo and save the place on the spot, with your location tagged automatically. Photos you take are saved to your Photos library too. FIND YOUR WAY BACK Get directions to any saved place by car, on foot, by bike, or on public transport, opened straight in Maps. SHARE THE GOOD ONES Send a place to a friend with the photo, the details, and a map link. If they use Come Back One Day too, one tap adds it straight to their own map. FIND ANYTHING, FAST Search across names, addresses, and notes, or filter your map and list by category to see just the restaurants, just the bars, or just the hotels. SYNCS WITH ICLOUD Your places sync privately across your iPhone and iPad through your own iCloud account. No separate sign-up, no account to create. Whether you're keeping a travel diary, building a list of favourite local spots, or just want to remember the name of that one place, Come Back One Day keeps it all in one place.

Validate with people who use this workflow before building.

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.
