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.

Turn your phone into a paranormal investigation toolkit. Spectre taps into your device's real sensors - microphone, motion, barometer, compass, Bluetooth, and camera - to log, visualize, and analyze the world around you during an investigation. WHAT'S INSIDE EVP Recorder & Analyzer Record real audio straight from your microphone. Watch a live waveform, frequency spectrum, and spectrogram as you capture. Spectre flags statistical anomalies in the audio (sudden level spikes that stand out from the background), with a voice-band filter, gain control, normalize, and WAV export. Live Sensor Dashboard A real-time command center pulling from your device's actual hardware: EMF & motion from the device's motion sensors Barometric pressure changes Compass heading Bluetooth proximity - detect nearby BLE signals and their strength Temperature from local weather data and your device's thermal state Anomaly Notifications Set the phone down and let Spectre alert you. When sensors detect anomalies during an active session, Spectre sends an OS-level notification so you don't have to watch the screen. Rate-limited to a maximum of 6 per hour. Toggle on or off in Settings. Thermal Vision Mode A FLIR-style "ironbow" color filter applied to your live camera feed, with on-screen anomaly highlighting and a compass HUD. (This is a visual effect on the standard camera. Your phone does not contain a thermal or infrared heat sensor, and this mode does not measure real temperature.) Investigation Sessions Start a session and Spectre logs every event with timestamps, duration, a threat-level summary, and - when location is enabled - GPS geotags you can review on a map. All sessions are saved on your device. Fully Customizable Tune detection sensitivity, EVP and EMF thresholds, audio filters, haptics, alerts, and per-location calibration to fit your environment. IMPORTANT - FOR ENTERTAINMENT PURPOSES ONLY Spectre is designed for fun, curiosity, and entertainment. It detects and visualizes statistical anomalies in your device's sensor readings - it does not detect ghosts, spirits, or any supernatural phenomena, and no such thing has been scientifically demonstrated. The "Thermal Vision" mode is a color effect applied to your regular camera. It is NOT a real thermal or infrared camera, captures no heat or temperature data, and the highlighted "anomalies" are based on image color, not actual heat. Readings throughout the app are not scientific measurements and should not be relied upon for any safety, medical, or environmental purpose. Some features (barometer, ambient temperature, EMF) rely on hardware that varies by device and may not be available on all phones.

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.
