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.

The infosphere, Visualized. Every time we use our phones, tablets or laptops we are entering an invisible world of wireless digital signals. It is a world that we cannot see but that is literally all around us. The Architecture of Radio is a 360 degree data visualization of what this world might look like. It shows the cell towers, GPS satellites and Wi-Fi routers around you that allow us to live our digital lives. New: support for Iphone X, XR, XS and XS Max Screens New: Cardboard support! Immerse yourself in the Infosphere in Virtual Reality using a cardboard or compatible headset* *Carboard support only for iPhone. iPhone 6s or newer recommended for best performance. Why should I use this app? Out of curiosity! We are increasingly dependent on a global ecosystem of digital signals. We use them for so many things, yet we cannot see them. We can see the roads we use to travel, the buildings we live in, but not the infrastructure that is changing the world. How can we understand this world without understanding how it works? The purpose of this app is to make the invisible visible so we can look at it, think about it and discuss it. Why Should I not use this app? This app is not a measurement tool. It’s purpose is to inspire, to see the world through a different lens. The app is based on real world data and gives you a pretty good idea of the density of digital signals around you, but it won’t tell you where to move the couch to get a better WIFI signal. So how does it work? The Architecture of Radio is a data visualization, based on global open datasets of cell tower, Wi-Fi and satellite locations. Based on your GPS location the app shows a 360 degree visualization of signals around you. The dataset includes almost 7 million cell towers, 19 million Wi-Fi routers and hundreds of satellites. Is this really what radio signals look like? We can’t see radio with our eyes. The waves that we use for our cell phones and Wi-Fi are way outside the spectrum of visible light. In order to “see” radio, it has to be interpreted or translated into an image that we can see. There are many ways to do that but it will always be an interpretation. The Architecture of Radio is an impression of the infosphere, a way of seeing it.

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.
