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.

E6BX is an essential app for pilots of all experience levels, offering a wide range of aviation tools designed to help you get comfortable with the reports and calculations required to fly safely. Included in this app are a visual E6B Calculator, interactive Weather Reports with METAR and TAF decoders, a NavLog Calculator, and many other tools to assist you with aviation calculations. E6B Calculator This is the world’s most popular E6B aviation calculator, already used online by hundreds of thousands of pilots. The calculations are visually illustrated to aid in understanding, showing wind speed and direction, wind correction angle, course, heading, ground speed, and true air speed. E6B is also known as CR, CRP-5 or in German, as the Dreieckrechner. E6B Simulator E6B Simulator offers a manual E6B with step by step instructions and highlights. This brings the same functionality on the website to the app. Weather Reports Search for any airport using the Weather Reports tool, and find the relevant METAR and TAF reports, taken live from aviationweather.gov. Need help understanding METAR or TAF? Tap on any segment to instantly see what it means, or tap the Decode button to reveal the entire report at once. Weather Reports can also display airport data for US airports, including runway directions and lengths, heliports, radio frequencies, and charts. NavLog Calculator Use the NavLog Calculator for either VFR or IFR flight planning. Enter numbers into the table to perform instant calculations. You can add as many lines as you need, and the table can be easily cleared with a single button. Holding Pattern Calculator The Holding Pattern Calculator uses a detailed and informative graphic to help you determine your entry into a holding pattern, and then to maintain that pattern with wind corrections. Simply enter a few basic values to see them instantly reflected in the graphic, then follow the detailed entry and hold instructions. Metar and Taf Decoder With E6BX Metar Decoder, almost everything in any given Metar or Taf is decodable, including elevation, wind direction and speed, wind components, pressure altitude, density altitude, air pressure, dew point, and all sorts of weather conditions. Snowtam & Motne Decoder Paste any Snowtam or Motne report into this tool to decode it. Almost everything in any given Snowtam or Motne is decodable, including type, depth, location, and extent of contamination. Aviation Unit Converter This tool includes all units commonly used in aviation. When you enter a value, it will instantly be converted to all other units of the same type. Convert units of time, distance, speed, pressure, temperature, volume, weight, and mass. Our GPS Coordinate Converter can convert between Decimal Degrees (DD), Degrees Decimal Minutes (DDM), and Degrees Minutes Seconds (DMS). Aviation Unit Converters include: Time Converter Temperature Converter Fuel-Weight Converter Reciprocal-Heading Converter VOR Radial-Bearing Converter Distance Converter Speed Converter Pressure Converter Area Converter Weight Converter Volume Converter GPS Coordinate Converter Additional Tools: Visual Wind Components Calculator Pressure Altitude Calculator Density Altitude Calculator Cloud Base Altitude Calculator Aviation Unit Converter Mach Speed/Speed of Sound Calculator True Air Speed Calculator Indicated Air Speed Calculator Airport Data NavLog Calculator Airport Lists by Country/State Weight and Balance Calculator METAR Decoder TAF Decoder SNOWTAM Decoder MOTNE Decoder Holding Pattern Calculator

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.
