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

Fourie is a watch only running app built by a group of running enthusiasts. Elevate your running experience with Fourie, a powerful and intuitive app designed specifically for runners who demand precision and flexibility in tracking all your runs. Whether you're training for a marathon, hitting intervals on the track, or enjoying a casual jog, Fourie delivers accurate GPS tracking, detailed stats, and seamless performance in a clean, runner-focused design. Two Intuitive Modes for Every Run • Split Mode Automatically split your run by distance or time. Set up 1 km, 1 mile, or custom intervals, and Fourie handles the timing and announcements effortlessly. • Lap Mode Take full manual control. Simply start your run and tap to mark laps or sets whenever you're ready. No pre-setup required. Lower your wrist to activate Rest Mode and skip adding lap count when you start your lap, so that your laps will be numbered correctly both during and after your run. Personalized Features to Keep You Motivated • Custom Audio Cues Tailor audio cues for pace, distance, time, splits, and more. You can choose your preferred order and frequency to stay informed without glancing at your screen. • Customizable Views Arrange your run screen exactly how you like it. Customize buttons and metrics that matter most to you for quick actions and gain at-a-glance insights during your workout. • Wrist Flick Gesture njoy seamless one-handed control during your workouts with intuitive wrist flick gestures. Customize them to effortlessly start or end runs, mark laps etc. without even looking at the screen. • Wrist Down Gesture For interval training, simply lower your wrist for a customizable duration to enter Rest Mode. Starting new laps won't advance the overall lap count, letting you track actual intervals without pre-planning. • Action Button Take full advantage of your Apple Watch Ultra's Action Button. Customize it to quickly start or end runs or mark laps right from your wrist. Detailed Insights Right on Your Wrist • VO2 Max Optionally display your estimated VO2 max after every run to track improvements in cardiovascular fitness and endurance. • Lap-by-Lap Breakdown Dive into detailed metrics for each lap, including pace, distance, and time, for precise analysis of your splits. • Heart Rate Zone Analysis Visualize time spent in each heart rate zone to optimize training intensity and recovery.

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.
