Feature spec
Goal: Send a clear invoice after finishing a job.
- Add a client, line items, a due date, and payment instructions.
- Preview the total before exporting a PDF.
- Keep an editable draft if export fails.

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
Monium puts superconducting-qubit physics in your pocket — a mobile companion to the open-source scqubits library, built for researchers, students, and the quantum-curious. Pick a qubit, tune its parameters with live sliders, and watch the physics update in real time: • Energy spectrum vs. any swept parameter • Wavefunctions over the potential (and in the charge basis) • Matrix elements as a heatmap, and vs. the swept parameter • T1 / T2 coherence times per noise channel • Exact computed values behind every plot, as tables Supported qubits: Transmon, Tunable Transmon (SQUID), and Fluxonium. Built for real work: • Enter the Josephson energy the way you measure it — critical current, junction inductance, or room-temperature normal-state resistance (with a cryo/room ratio). • Save and reload presets per qubit. • Convergence indicators so you can trust the numbers. Everything runs on-device. No account, no ads, no tracking, no network — your work stays on your phone. Monium mirrors scqubits' conventions and is validated against it, so the numbers match the desktop tool you already trust.

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.
