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

Now with Apple Watch Series 5 Magnetometer support. Featuring: 1. Precision GPS Heading Compass 2. Magnetic compass - Apple Watch supported using pointer mode unless installed on Apple Watch Series 5 3. GPS Path Recording 4. Precision Speedometer 5. Destination Pointer 6. Google Maps integration How are we different from other compass and navigation apps? Northern is a powerful navigation tool that lets users cross validate and compare multiple directional/navigational readings within a single unified interface. We believe this is a fantastic solution to a hard problem, namely that no one source of information is ever 100% accurate. In short, Northern is designed to help our users more confidently and reliably decide which direction they are heading. Our specialized, dual compass display is shown alongside Google Maps, providing a single, simple, focused interface, designed from the ground up to more effectively orient you within your environment.  More reliably locate North South East and West, or even better, select a destination from our map - Northern will then display an arrow that locks onto these coordinates even while you move from one point to the next. Compass Types * Compass #1 - GPS Heading Compass - Extremely accurate given a strong enough GPS signal and straight enough path - Works on your Apple Watch while your phone is in your pocket - Users can select how many samples they want to include with each direction reading - up to 60 for very long paths or as few as 3 for more responsive readings - Each new GPS location sample is analyzed along with all other samples providing a continuous solution - Each solution is then run through a specialized algorithm that calculates an approximate accuracy - GPS hardware doesn't suffer the same type of magnetic interference as the magnetometer driven magnetic compass (Compass #2 below) Compass #2 - Magnetic Compass - Now available on Apple Watch Series 5 - More sensitive then the GPS Heading Compass - Includes hardware accuracy reporting - Our new pointer mode lets you view your iPhones magnetic compass readings on your Apple Watch NEW FEATURES Path generation Simple start/stop path recording lets you track your location over time. Speedometer Precision GPS analysis returns your speed in miles/kilometers per hour. Utilizes our high accuracy heading compass algorithms. Northern is Great for ... ... wanderers ... ... those with a poor sense of direction ... ... people who like to explore, know where they are, but not necessarily require a rigid set of directions. Extra Features... Integrated Apple Maps into our Apple Watch extension. Users can reference surrounding streets and other landmarks right from their wrist. Northern also uses Google Maps on your mobile device. Users can toggle between terrain, satellite or hybrid modes. We've also integrated Google Places, letting users quickly search for any destination with only a few taps. Fun sharing features, including a scavenger mode, let users leave scrambled messages for one another - just find the location to unscramble. * Apple Watch Series 5 is currently the only Apple Watch model with magnetometer hardware. Previous Apple Watch models sample magnetometer readings from paired iPhone hardware. All GPS location and heading readings also come from your paired iPhone hardware.

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.
