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.

Spirit Bell – Paranormal Detection Tool A modern take on the infamous Dead Bell device – but with more sensors! The Spirit Bell app detects environmental changes and rings the bell when anomalies are detected. Whether you're on a ghost hunt or conducting a paranormal investigation, this tool can help you monitor unseen activity. ******************************* How to Use Place your phone in the desired area Tap "Calibrate" – This sets a baseline for sensor readings Step away & let the app do its work If movement or environmental changes are detected, the bell will ring! DO NOT move the phone after calibration. If you need to reposition, simply press "Back", move the device, and recalibrate. ******************************* Multiple Sensor Detection The Spirit Bell app uses a variety of sensors to detect environmental changes: The sensors used are: Magnetometer - This senses Magnetic and Electromagnet fields around the device Accelerometer - This senses any device movement and the slightest vibrations around the device Barometer - Detects any change in the Ambient Air Pressure around the device Compass - Detects the slightest change in magnetic interference to Magnetic North GyroScope - Detects the slightest movement of the device Orientation - Detects the slightest movement to the position of the device Not all devices have every sensor! The app will automatically use the available sensors and display "Sensor Not Found" for missing ones. ******************************* Adjust Sensitivity – If certain sensors are too sensitive and generating false positives, you can disable individual sensors by tapping their box on the screen. ******************************* Disclaimer Use at your own risk! The developer is not responsible for any paranormal or other outcomes resulting from using this app. Refer to our website for a full list of terms and conditions http://www.spottedghosts.com

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.
