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.

Bob is the app that turns your Apple Watch and your iPhone into a smart sensor and you into a scientist. Smartwatches have 6 of the same sensors that scientists use to study the ocean and the earth. Take, save, and share environmental data with anyone, anywhere, anytime. ~~~ Data collection simplified. ~~~ Tap a button to start logging data. Done logging? Tap again. ~~~ Geotagging? ~~~ L1 and L5 GPS, GLONASS, Galileo, QZSS, and BeiDou works seamlessly with local Wi-Fi and Bluetooth networks to provide location and altitude at accuracies up to 10 meters. ~~~ Moving three-dimensionally through space? ~~~ The accelerometer, gyroscope, and compass tracks watch motion. ~~~ Air pressure? ~~~ There's a barometer for that. ~~~ Are you in water? ~~~ Apple Watch Ultra, Series 11 or Series 10 also measure water temperature and depth to 0.1 C and 0.05 meters. ~~~ Set it and forget it! ~~~ Automatic water lock for uninterrupted data collection. ~~~ The more the merrier!~~~ Record data on your watch and your phone at the same time. ~~~ Automatic archiving ~~~ Tap stop and your data is automatically saved to iCloud. ~~~ Explore your data. ~~~ The watch logbook has a quick summary. For more details, graphically explore your data on the phone app. ~~~ Share like a text or photo. ~~~ Instead of sending a cat pic to Nana and PopPop, send them your latest data. Converted internally to a human and machine readable JSON, they will also be impressed by the comprehensive metadata. ~~~ Hit us with your feedback ~~~ If you find a bug or have an idea for a cool feature, reach out by emailing [email protected] _______________________\\ Tini Scientific is on a mission to provide ocean data to anyone, anywhere, anytime.

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.
