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
PulseOSC seamlessly bridges your Apple Watch, compatible headphones (AirPods Pro 3, Powerbeats Pro 2), or third-party Bluetooth devices health data with your OSC-compatible applications (like VRChat or Resonite). Whether you want to drive avatar animations with your heart rate or display it in the chatbox, PulseOSC makes it simple and reliable. Real-Time Heart Rate: Streams your live heart rate from Apple Watch, compatible headphones (AirPods Pro 3, Powerbeats Pro 2), or third-party Bluetooth devices to your device via OSC. VRChat Ready: Native support for Avatar Parameters (drive animations/effects) and the VRChat Chatbox (display BPM text). Fully Customizable: Configure target IP, Port, and specific OSC addresses to fit your unique setup. Visual Feedback: A beautiful, modern interface that lets you monitor connection status and data flow at a glance. Privacy First: Your data stays under your control. PulseOSC only transmits health data directly to the local IP or domain you specify—no external cloud servers involved. *This application is not authorized, endorsed, or supported by VRChat Inc. or Yellow Dog Man Studios S.r.o. Only the heart rate data it sends via the OSC protocol can be retrieved by the VRChat or Resonite clients. Beyond this technical interaction, there is no affiliation between them.

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.

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.
