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.

Partometer3D is camera measure app for area, perimeter, length, ratio, circle parameters, angle measurements. It can be used as a ruler or tape measure for accurate measurements on pictures / photos. This app allows users to make measurements in any defined plane in 3D space. Info and demo video: http://goo.gl/UpCKrR The measurement / object plane doesn't have to be parallel to the camera plane. It expands number of situations where application can be used. For example, big objects now can be measured by taking a picture from a side, objects and distances that are difficult to reach can be measured as well. Partometer3D has the same application area as "Partometer - camera measure", but gives you more flexibility and power. Angle Mode can be used for roof angle measurements. This data can be used in SolarMeter app for solar energy calculations. The app has the following distinctive features: - measure in any selected plane in 3D space - Length, Angle, Area, Circle Modes - add/delete any number of measurement/ruler lines - values assigned to each ruler line - measure objects in different directions - share measurements - find object ratios, if you don't need absolute measurements - compare object parts to each other - use custom and predefined reference objects - angle measurement partially visible or out of view - irregular shaped area measurements Partometer3D uses a phone/tablet camera and any available object with known size as a reference to perform measurements. To define the measurement plane a rectangular object (sheet of paper, credit card, custom object) is used. The App shows measurement results in different units: meters, millimeters, centimeters, feet, inches based on user settings. It also calculate dimensions of the object in relative units with respect to the reference object (ROL). There is an option to make a picture or upload picture from Library. Zoom View feature helps to align object boundaries accurately. "Partomter3D - camera measure" can be very useful if you need to measure bigger distances on a plane, where the simple ruler or tape measure is difficult to apply.

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.
