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

Accurately display your GPS speed, temperature, time, distance, heading, course, altitude and barometric pressure. Easy to read dials, while keeping your location data private. Terrene Dash is a dashboard app, which clearly and accurately displays your current speed, temperature, direction, altitude, time, and barometric pressure at a glance. With 7 configurable dashboard pages, you can choose which dial you want on each page, and swipe left or right to quickly switch between dashboards. Terrene Dash has light and dark modes. Its dark mode, with its black background and muted markings, helps your eyes stay adjusted to the dark, while light mode has good contrast in bright daytime conditions. My goal is for Terrene Dash to be a handy toolbox of time, motion, environment and navigation related dials, using all the capabilities of modern iPhone devices, while ensuring your privacy is kept safe. Dashboard dials → Altimeter ▫ Feet ▫ Meters → Tap the dial to toggle between whole and decimal numbers → Barometer ▫ Hectopascals (hPa) ▫ Kilopascals (kPa) ▫ Inches of mercury (in Hg) ▫ Millimeters of mercury (mm Hg) ▫ Pounds per square inch (psi) → Tap the dial to toggle between whole and decimal numbers. In Hg, kPa, and psi will toggle between 1 and 2 decimal numbers → Compass ▫ Magnetic north ▫ True north → Course Over Ground (COG) ▫ Your actual current direction relative to the surface of the earth. → Clock ▫ 12 or 24-Hour ▫ In current timezone → Speedometer ▫ Kilometers per hour (km/h) ▫ Miles per hour (mph) ▫ Knots (kn) ▫ Meters per second (m/s) → Speedometer stats ▫ Four trip meters and top speed ▫ Tap to cycle between each ▫ Press and hold to rename, reorder, configure when each are reset or manually reset ▫ Configure them to automatically reset after midnight each day, week, month, year or never → Tap the dial to toggle between whole and decimal numbers → Temperature ▫ Powered by Apple WeatherKit ▫ A colour-coded forecast arc shows today's high and low ▫ The dial range adapts automatically based on your local 3-day forecast ▫ Tap the secondary display to cycle through feels like, today's forecast, humidity, and dew point What's next? More dials and improvements are on the way. If you've a great idea for a dial or a feature you'd love to see in Terrene Dash, please email me (Simon) at [email protected].

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.
