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.

Different number of the detected sound, different reaction from this app. Without tapping our devices, put our devices one meter or even two meters away, make the single sound one by one, the different number of the detected sound, different reaction from this app, the reactions could be 1 record video 2 take photo 3 record sound 4 play music or sound file 5 report time 6 talk notes in different languages. The number of detected sound could be from one to six. The duration of sound counting could be from 5 seconds to 30 seconds. For example, if the duration of sound counting is 12 seconds. Then after 12 seconds since this app detects the first sound, only another single sound is detected, then the number of detected sound is two. If we just use this app for the first time, according to the default preferences: the reaction for Sound One is to record video, the reaction for sound two is to record sound, the reaction for Sound three is to take photo. The reaction for Sound four is to play sound music. The reaction for Sound five is to talk note. The reaction fo Sound six is to report the current time. From the setting view, we could select to use the front camera or rear camera. we could set the duration for recording sound or recording video. we could set the detected pitch level of sound. Only the sound pitch is higher than the level we indict, the sound will be counted. From the reaction+data view, we could edit the notes for talking and we could select which sound file should be played, and we could also view the photos and video clips taken by this app. This edition only could detect single sound. That means, when we make the sound for the first time, after that, we need to wait about one or two seconds and wait the detected pith level of the sound going down to the level less than the detected sound level we indict, after that when we make another sound, the app could detect the sound. After we already make a detected sound and before we want to make another detected sound, it is very important to wait the detected pitch level of the sound going down to the level less than the detected level we set in the setting view.

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.
