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

Do you ride with an app like Bosch eBike Flow, Garmin Connect, or Wahoo? Flow Sync imports your FIT files directly into Apple Health, effortlessly. — IMPORT YOUR CYCLING SESSIONS Flow Sync reads your FIT files and adds them to your Apple Health history in seconds. Power, cadence, heart rate, speed, elevation, GPS route: all your cycling data is preserved and available in the Health app or the Fitness app. Flow Sync also imports the heart rate recorded during your ride, whether it comes from a chest strap, a sensor built into the bike, or any other accessory compatible with your e-bike. — CREATE OR ENRICH Two import modes to fit your needs: • New workout — Flow Sync creates a complete cycling workout in Apple Health from your FIT file, with all available data series. • Enrich an existing workout — Already have a workout in Health (logged manually, via Apple Watch, or another app)? Flow Sync injects the missing data from the FIT file: power, cadence, GPS route, and more. — SUPPORTED DATA Flow Sync imports all data available in your FIT file: • Power (watts) • Heart rate (bpm) • Cadence (rpm) • Speed • Cycling distance • Elevation and elevation gain • Full GPS route • Calories (calculated from power) • Pauses and resumes — FIT COMPATIBLE Flow Sync is compatible with FIT files generated by major connected cycling apps, including Bosch eBike Flow. — SIMPLE AND FAST Open your FIT file from the Files app, from the Bosch eBike Flow app, or any share sheet — Flow Sync handles .fit file association. A few taps, and your ride is in Apple Health. No account, no sign-up, no subscription. Flow Sync respects your privacy: your data never leaves your iPhone.

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.
