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.

GyPSy Guide GPS driving tour of Kauai is an excellent way to enjoy a sightseeing trip to explore the entire island. There are 280+ audio points that play automatically, featuring what to see, stories, tips and advice. All the benefits of a guided tour, the freedom to drive yourself. TOUR GUIDE FOR SCENIC DRIVES ON KAUAI If you like driving yourself when you go sightseeing, GyPSy Guide™ tour apps allow you to enjoy a guided tour experience while remaining totally independent. By driving yourself, you'll be able to get from place to place faster, see more things and not be tied to anyone else's schedule. DON'T MISS OUT ON THE BEST SIGHTS AND STORIES The tour apps use your device’s location abilities to play the commentary AUTOMATICALLY. All you have to do is drive, listen and decide which places you want to stop at. Our tour guides have created an insightful and entertaining tour of Kauai. We’ll recommend the best places to experience and some great locations that most visitors will drive by. PLAYS AUTOMATICALLY GyPSy Guide knows where you are and which direction you are heading, and plays commentary automatically about the things you are seeing, plus stories and tips and advice. EXPLORE LIKE A LOCAL It’s just like having a local friend to show you around. And that friend just happens to be a professional tour guide. GREAT VALUE The same information you would get on a bus tour or from a guide book, for just a fraction of the price. And you control the itinerary and schedule. WORKS OFFLINE No data, cellular or even wireless network connection needed while touring. Download over Wi-Fi before you tour. Anyone can use them with no need for roaming data – even visiting from another country. DRIVING TOUR ROUTE The tour has commentary everywhere on the island that you will want to explore. We recommend dividing the island into at least 2 driving days. 1) North and Eastern Kauai. This half of the island tours through the famous northern beach and resort areas of Hanalei and Princeville. The tour continues all the way to the end of the road at Ke’e Beach. Between Princeville and Lihue we’ll explore many fine beaches and the vibrant town of Kapa’a. 2) South and Western Kauai. The resort area of Poipu is home to south shore's best beaches and the island’s most famous blowhole. Drive further for the artsy town of Hanapepe. From historic Waimea, we travel up Kauai’s volcanic mountains to the superb Waimea Canyon and continue to the awe-inspiring viewpoints of Koke’e Park perched above the Na Pali Cost. There’s much more to see as we drive and GyPSy will be you very own tour guide all the way. NOTES Download the app on Wi-Fi from your network at home or use any free Wi-Fi network. Because the app is filled with audio commentary and maps, its larger than "normal" apps. Many phone/data networks may block the download because of size - so its important to download over a Wi-Fi network. ++ Continued use of GPS running in the background increases battery usage - we strongly recommend taking a cigarette style DC outlet car charger. This is much better than simply plugging into the USB port in a vehicle. ** iPad users - please note that WiFi-only iPads will not activate the commentary automatically. Any iPhone or network-capable iPad (WiFi + Cellular - whether you have a network connection or not) will work just fine. ABOUT US GyPSy Guide™ produce award winning audio tours along scenic drives around the world. Enjoyed by travelers who prefer to set their own pace and itinerary on vacation, but enjoy a fun, informative and educational guided experience. Our goal is to provide a great introduction to the region and perhaps inspire you to learn more and return. None of our apps include paid advertising or placements for benefit.

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.
