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

Your SkiErg just got a whole lot more interesting. SkiEr turns your Concept2 PM5 into an immersive training experience. Connect via Bluetooth, pick a route, and ski through procedurally-generated 3D terrain — pine forests, mountain cabins, frozen lakes, and dynamic weather. Every stroke on your erg moves your skier forward in real time. It's like Zwift, but for the SkiErg. IMMERSIVE 3D ROUTES Ski 7 unique routes across varied terrain: • Alpine Sprint (5K, Easy) — Pine forests and gentle hills • Glacier Trail (5K, Moderate) — Icy valleys at sunset • Twilight Ridge (5K, Hard) — Moonlit ridge running • Nordic Valley (10K, Moderate) — Classic cross-country • Frozen Lake Loop (10K, Hard) — Heavy snowfall, low visibility • Sunset Peaks (10K, Moderate) — Golden hour mountain passes • Mountain Pass (21K, Extreme) — Half-marathon at altitude EARN MEDALS Every route has bronze, silver, and gold medal targets based on your pace. Chase the gold. Beat it. Then do it again. RACE YOUR GHOST PB A translucent skier representing your personal best glides alongside you. See exactly where you're ahead, where you're behind, and where to push. STRUCTURED TRAINING PLANS Follow one of 6 built-in plans to improve: • Beginner 4-Week — Build form and consistency • 5-Week 2K Improver — Chase your 2K personal best • HIIT Sprint Series — Pure power and speed • 6-Week Endurance Builder — Go longer, go further • Hyrox 1K Specialist — Train specifically for race day • Biathlon Conditioning — Build repeat power and recovery REAL-TIME PM5 CONNECTION Connects to your Concept2 PM5 via Bluetooth using both FTMS and Concept2's own protocol. See live pace, watts, stroke rate, distance, calories, and heart rate — synced stroke by stroke. INTERVALS THAT PUSH YOU Custom intervals with configurable work time, rest time, and rounds. Clear on-screen phase indicators and voice cues keep you locked in. TRACK EVERYTHING • Full workout history with detailed breakdowns • Personal records: fastest 2K, 5K, 10K times • Weekly trends over 12 weeks • Streak tracking • 25+ achievements across 6 categories WIDGETS Three widget types for your Home Screen and Lock Screen: Last Workout, Weekly Summary, and Streak.

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.
