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
ROS Topic Viewer is an iPad-only field debugging tool for robotics engineers. Connect directly to your ROS 2 robot over Wi-Fi using rosbridge_suite WebSocket — no laptop required. Browse all available topics, inspect live raw JSON data in a scrollable tree, and monitor message rate in real time. FEATURES • Connect to any ROS 2 robot via rosbridge WebSocket (ws://) • Live connection log — see every step transparently: handshake, topic fetch, reconnect attempts, and failures • Browse and search all published topics with message type annotations • Inspect raw JSON data as a live expandable key-value tree • Real-time Hz and message count per topic • Pause to freeze data at a moment in time • Export topic snapshot as CSV and share via AirDrop, Files, or email • Auto-reconnect with exponential backoff when connection drops DESIGNED FOR FIELD ENGINEERS Onsite robot debugging without a laptop. Connect your iPad to the same Wi-Fi network as your robot, enter the rosbridge WebSocket address, and start inspecting topics immediately. No configuration, no ROS installation required on the iPad. Compatible with iPad running iPadOS 16 or later.

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.

BUILD KIT DIFFICULTY
Intermediate
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.
