Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

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.

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

SpeakerAngle is the first app that allows you to precisely measure and adjust speaker toe-in angles with your iPhone, iPad, or iPod Touch in order to get the most out of your audio system. SpeakerAngle works with any speaker make or model, in stereo and surround sound systems. Plus it's easy and intuitive to use, with no need for WiFi or Internet connectivity. Key Features • Allows the accurate setting and matching of critical speaker angles for optimum sound quality. • As you adjust a speaker in the room, on-screen speaker icons move and continuously update to display the current speaker angle. • Onscreen number boxes change color to let you know when left and right speaker toe-in angles are identical. • Includes user guide that can be printed or shared. • Projects are automatically saved as you work and can be freely renamed and recalled. To use SpeakerAngle, simply create a stereo or surround sound project and name it. Then adjust your speakers so they are facing straight ahead. Place your iPhone, iPad, or iPod Touch on top of one of the speakers and press the corresponding onscreen icon, then rotate that speaker towards the listening position. As you do so, SpeakerAngle's onscreen display shows you the angle, using red-green color coding to guide you through a range of recommended angles. Next, do the same for the paired speaker in your system until its icon's number box becomes yellow in color, indicating that both speakers are identically angled. A handy onscreen Reset button allows you to start from scratch at any time and experiment with different toe-in angles. When you're ready to fine-tune your system, a menu option allows you to purchase our companion app, SpeakerPro, which allows you to take precise distance measurements and receive intelligent toe-in recommendations. Available on the App Store now!

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.

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.
