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.

The easiest paranormal app to use. Powerful enough for experts or beginners. Simulates a radio but uses sensor data to generate the sound. Vocal sounds are built from the real raw data, pieced together and the system determines the closest words or phrases to the speech. FEATURES INCLUDE: + Uses real sensor data to detect changes in electromagnetic fields (EMF) or the tiniest of vibrations - your choice. + Speech sounds are generated from the sensor data to form words. It then lists what it thinks is being said (closest guess). + Export speech audio as WAV files to save, share or play in other applications. + Automatic continuous calibration of sensors. + Stores the last 300 speech patterns to look back on, replay, share and export. + Designed from the ground up to be easy to use but powerful, using a completely custom built speech synthesis system. TIPS & HELP: + The app works best if you place your device on a solid flat surface. Both electromagnetic fields and vibrations can fluctuate wildly if you hold or move your device. + If your device does not contain a magnetometer sensor for detecting electromagnetic fields the app will fall back to detecting vibration & movement automatically. + Some devices can take a while for the magnetometer/electromagnetic sensor to start working properly when first activated so you may need to wait a few minutes. + If you get lots of false readings then you may need to move your device away from any source of interference. + It will automatically calibrate the sensors but you can force a calibration by tapping a detection mode button ("EMF" or "Vibration"). + The app will take a "best guess" at what the speech is saying but you may feel it is saying something different. + Do not always trust what is being said. If you are unhappy about it or it says anything you do not like, consider it interference from the sensors. + A free LITE version will be available (with no export feature and only saving the last 20 speech patterns) to try. MORE INFORMATION: + The app does not require any unnecessary permissions. + No internet connection is required to use the app. No information from your device is collected by the app. + The app contains no advertisements or in-app-purchases. + More details at: https://www.worldbydesign.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.
