Generating… usually about a minute.
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.

Do you have tinnitus or “ringing in the ears”? Tinnitus HQ helps you understand and relieve your tinnitus symptoms. Recent research shows that tinnitus can be treated by listening to sounds that have been filtered to remove your specific tinnitus frequencies.* With Tinnitus HQ, you can apply advanced filters to over 500 high-quality sounds to find relief for your symptoms. Simply apply a bandpass filter to any sound or mix to isolate frequencies in a narrow range. Move this filter up and down the frequency range until it closely matches the ringing frequency in your ears. Add a bandstop filter at these frequencies to any sound or mix to create your tinnitus mask. The advanced filters can be applied to both ears or just one ear, and different frequency ranges can be used for each ear. You can set a wide range of filter widths from 0.1 to 4.0 octaves, down to 1Hz resolution. And you can adjust the volume level in each ear with a single balance control. With Tinnitus HQ you can create advanced natural-sounding tinnitus masks to help relieve your tinnitus symptoms. Tinnitus HQ features: • Over 500 high-quality natural sound recordings • Precision bandpass and bandstop filters to identify and mask ringing frequencies • Wide frequency range: 128 Hz to 16 kHz • Filter widths from 0.1 to 4.0 Octaves, settable to 1Hz resolution • Two-ear and single-ear filtering capability • Independent Left-Right ear filter frequencies and widths • Left-Right ear volume balance control • Easy-to-create blended mixes of any 4 sounds • Runs in background while using other apps or when the screen is locked • Timer with slow audio fade-out • Beautiful high-definition images from around the globe • Modern easy-to-use interface • 15 different natural sound categories, including Rain, Rivers & Streams, Ocean, Lakes, Wind, Water Fountains, Fire, Birds, Crickets & Insects, Cars, Trains, Public Places, Household, Industrial, Soundscapes.

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.
