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.

• Ghost EVP Radio - Spirit Box, EMF & Motion Tracker Step into the world of the unexplained with Ghost EVP Radio - a powerful ghost hunting experience that combines spirit box audio, EMF readings, and now a motion tracker into one immersive app. Whether you’re a curious explorer or a seasoned paranormal investigator, Ghost EVP Radio gives you the tools to experience EVP phenomena and energy fluctuations in real time. • What Is EVP? EVP (Electronic Voice Phenomena) are mysterious sounds that resemble human speech and often appear in audio recordings. Many ghost hunters believe these voices may come from spirits or energy-based entities. Ghost EVP Radio recreates the classic spirit box experience, generating real-time audio from randomized signals and surfacing potential words and phrases for you to explore. • Advanced Paranormal Tools Real-Time Audio Engine Our advanced speech and noise generators emulate spirit box behavior and attempts to surface meaningful words from the randomized signals. EMF Scanner Uses your device’s built-in magnetometer sensor to detect real electromagnetic field changes. Motion Tracker Powered by your device’s accelerometer to help you monitor unusual movement or vibrations in your environment. Smart Recordings Record manually or let the app auto-capture when anomalies are detected. Save, share, or analyze your sessions anytime. Audio Visualization Watch signals unfold with the built-in Oscilloscope, Spectrometer, and Voicegram. Text Log Every detected word is logged for later review, sorting, or sharing. Custom Alerts Set vibration, audio alarms or even the device flashlight to notify you of anomalies in real time. Themes & Personalization Switch between multiple user interface themes to fit your mood or environment. • How to Use Be patient. Like a real ghost box, the app needs time to calibrate and begin detecting possible anomalies. Results may vary depending on your environment, sensor accuracy, and noise conditions. Don’t expect instant voices - give it time and explore with an open mind. • Languages Full support for English, German, French, Italian, Spanish, Dutch, Czech, Polish, Portuguese, Slovak, Swedish, Turkish, and Latin. • Disclaimer Ghost EVP Radio is designed for entertainment and exploration. While inspired by tools used by real ghost hunters, the results cannot be scientifically verified. Use responsibly and with an open mind. Get Ghost EVP Radio today and, like hundreds of thousands of users already have, turn your mobile device into a complete ghost hunting kit - with spirit box, EMF scanner, and motion tracker in one app. A fascinating eye-opening experience that is more powerful than ever before.

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.
