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 surprise that wakes your attention up. Silent Bell taps your wrist at random moments — a mindfulness bell for Apple Watch that never makes a sound. It divides each hour into equal stretches and places one tap at random inside each, so there is no rhythm to learn and nothing to brace for. Every tap arrives unrehearsed: spaced far enough apart to never feel like an alarm, unpredictable enough to keep working. Each one is a small, private question — where is your attention right now? TRULY SILENT, TRULY PRIVATE No sound. No banner. Nothing on your watch face. Nothing in Notification Center. The people around you will never know — there is nothing to see or hear. Just a gentle tap, felt only by you, even with your wrist down and the screen dark. WORKS THROUGH EVERY FOCUS Because the taps are not notifications, Do Not Disturb, Sleep and Work Focus cannot silence them. Your iPhone can be in another room, or off entirely — Silent Bell runs on the watch alone. MADE TO GET OUT OF THE WAY • 1 to 10 taps an hour, placed at random and never clustered • A minimum gap, so two taps never land on top of each other • Choose how the tap feels, from nine built-in patterns • No account, no network, no analytics — there is no data to collect AN HONEST NOTE Apple limits how long any app may run in the background to one hour. When Silent Bell reaches that limit it pauses, gives you a distinct pattern you'll learn to recognise, and one tap resumes it. It is a platform limit rather than a choice, and it makes a fair bell of its own: once an hour you notice that the noticing stopped, and you choose to begin again. REQUIRES Apple Watch with watchOS 10 or later. There is no iPhone app to install. The source code is public and auditable at github.com/jakublipinski/Silent-Bell — every line the app runs, readable by anyone.

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.
