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

Avy savvy backcountry skiers and riders know that three things count when it comes to the terrain’s influence on avalanches: the slope, the elevation, and the (compass) aspect. And the Avalanche Inclinometer delivers all three. Sure, you can find plenty of inclinometer apps (also known as clinometers) that are designed for carpenters, but Steve's Avalanche Inclinometer is meant for people who spend time in avalanche terrain. This app shows the slope, elevation, and aspect in BIG FONTS which are perfect for tired eyes in stormy (or bright-and-too-sunny) weather. And it doesn’t display a gaggle of tiny buttons and widgets to decipher when you should be skiing. You can sight across a slope by holding your phone parallel to the slope, or you can sight up or down a slope by sighting along the long-edge of your phone like a gunsight. (Through-the-camera sighting is nifty when the light is just right, but it often isn't.) When you have your phone aligned with the slope, a single tap on the screen will lock the data so you can read it. The Avalanche Inclinometer will even speak to you as you’re measuring the steepness so you won’t need to look at the screen. And the BIG inclinometer dial changes colors based on the slope which provides instant feedback on how the steepness of the terrain is contributing to the likelihood of an avalanche. After measuring the slope, you can tap a single button to share your current GPS location, the slope in degrees, and the elevation. The email includes kml and gpx waypoint files, and a link that will let you quickly see the location in any browser. You can enter the email address one time and the Avalanche Inclinometer will remember it for next time. Less typing; more skiing. The Avalanche Inclinometer isn’t free, but apps don’t grow on trees. To buy this app you’ll spend less than buying a beer at a ski resort—think of it as buying Steve a beer! In addition to the Avalanche Inclinometer, it is important that you take an avy class, pay attention to the avalanche red flags, use good route finding techniques, and practice your avalanche rescue skills frequently

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.
