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 best and most accurate app for Cuckoo and Pendulum clocks calibration. Easily measure your Clock beats period and adjust it to a known correct value. Turn your iPhone into a precise train count sensor with an unbelievable 0.001 milliseconds (1μs) accuracy!! Get a quick and precise drift reading of how many seconds/minutes your clock is going to gain or loose per day. Every Cuckoo Clock owner knows that a mechanical clocks are not as accurate as modern day quartz clocks. This is because the clock mechanism is influenced by temperature, humidity, barometric pressure, breeze and others environmental conditions and therefore requires frequent adjustment. When you are regulating the pendulum of your Cuckoo Clock today, you are attempting to achieve the best timekeeping possible by a trail and error method by lifting the pendulum bob up or down and hope for a better accuracy. Using this app you can finally get a reading of your Clock ticks timing and precisely calibrate it to a known value. How to calibrate your Clock using this app: 1. Run this App and measure your Clock timings using the iPhone microphone 2. Use the Signal Gain and the Detection Threshold sliders to adjust the measured signal 3. Select a reference timing for calibration from the clock reference table or set your own reference timing 4. Read the accuracy level of your clock vs. the reference timing 5. Adjust your Clock pendulum bob to get the best accuracy! 6. Review how many seconds/minutes your Clock will gain or lose per day based on your current calibration The app will presents your Clock beats period reading as well as BPH (beats per hour) and BPM (beats per minutes) values. An accurate waveform display of the microphone signal will help you to adjust the tick readings for the best measurement. Animated Indicators will guide you through the calibration process. Manage the app Reference Timings table and add user defined clocks in addition to the predefined ones to support all your clocks. This app will turn your iPhone into a powerful measurement tool which normally costs hundreds of dollars.

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.
