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

Here's your description with the Apple Watch section removed — everything else untouched: --- Coach to Catcher lets coaches call pitches directly to their catcher's earpiece without anyone else knowing. No hand signals to steal. No trips to the mound. Just tap the pitch type, tap the location, and the audio plays instantly through a connected Bluetooth earpiece or AirPod. Built for real game speed. The entire interface is designed for one handed use under pressure. Select a pitch, select a zone on the 3x3 grid, and hit send. The catcher hears a clear voice call like "Curveball, Low and Away" in under a second. FEATURES Pitch Calling: Choose from up to 6 customizable pitch types. Tap a location on the strike zone grid and send the call instantly. Lefty/Righty Toggle: Flip batter orientation with one tap. Inside and away locations swap automatically so the call is always correct from the catcher's perspective. Quick Actions: Bunt, Backpick (1st, 2nd, 3rd), and Pick Off (1st, 2nd, 3rd) are all one or two taps away with no pitch or location selection needed. Pitch Out and Step Off: Special situation buttons sit right above the zone grid for fast access. Audio Output Options: Route audio to any Bluetooth device using the built in output picker. Works with Bone Induction, AirPods, single ear coaching earpieces, and wired headphones. Coach to Catcher was designed by a coach, for coaches. Every feature exists because it solved a real problem on the field. No subscriptions. No ads. Just a tool that works when the game is on the line.

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.
