What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Turn your iPhone into a precision navigation instrument. Whether you're hiking a mountain trail, finding your way through an unfamiliar city, or simply need to know which direction you're facing — this compass delivers accurate, real-time heading with a beautifully crafted interface. PRECISION COMPASS A finely detailed compass rose with smooth needle movement shows your exact heading in degrees or mils. Switch between magnetic north and true north with a single tap. The large, easy-to-read display shows your cardinal direction, numeric heading, and GPS coordinates — all updating in real time. CAMERA OVERLAY MODE Activate the telescope mode to see compass data overlaid directly on your camera feed. Align real-world landmarks with precise bearings. Perfect for orienteering, surveying property lines, or identifying distant peaks on a hike. INTERACTIVE MAP View your position and heading direction on a full interactive map. Switch between standard, satellite, and hybrid views. Save important locations — your parked car, a campsite, a trailhead — and navigate back to them with distance and bearing displayed at a glance. Share any saved location with friends and family instantly. PROFESSIONAL TOOLS Three built-in tools replace separate apps: • Bubble Level — A precision spirit level using your device's motion sensors. Shows pitch and roll angles with a clear visual indicator. Know instantly when a surface is perfectly flat. • Speedometer — Real-time GPS speed displayed in km/h, mph, or knots. Tracks your maximum speed and shows current course and altitude. Ideal for road trips, cycling, or boating. • Qibla Finder — Calculates the exact bearing and distance to the Kaaba from anywhere in the world. A dedicated compass arrow points toward Qibla, with a confirmation indicator when you're facing the correct direction. BUILT FOR THE OUTDOORS Works completely offline — no internet connection required for compass, level, or speed readings. The dark interface is designed for readability in bright sunlight, and an optional night mode switches to a red-on-black display that preserves your night vision during stargazing or night hikes. THOUGHTFUL DETAILS • Haptic feedback when crossing cardinal directions • Heading accuracy indicator with calibration guide • Multiple coordinate formats: decimal degrees and DMS • GPS altitude display • Low-pass filtered heading for smooth, jitter-free needle movement • Supports both portrait and landscape orientation No ads. No subscriptions. No account required. Just open the app and start navigating. Designed for iPhone. Requires iOS 17 or later.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
