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.

Apple Watch, Nest Thermostat, and Siri. Together at last. * The app has Siri Voice shortcuts for seamless Siri control of your Nest, from the iPhone, Watch, iPad, and HomePod. It fully supports Apple Watch 5G/LTE, and can work when the iPhone is not around - as long as the watch itself has internet access (either 5G/LTE or WiFi). * The app lets you monitor and control HomeKit thermostats like Ecobee, and functions largely the same with them as it does with Nest, except for the Siri Shortcuts functionality which is not needed with HomeKit. It lets you see your thermostat info on the Watch complications, and control it using the iOS widget. _____________ • Using Siri voice shortcuts you can control many aspects of your Nest, such as instant activation of heating or cooling, setting the temperature by saying how many degrees you want to set, increasing/decreasing the temperature, and setting the Home/Away state. Thanks to Thermo Watch, It's all finally just one casual "Hey Siri" away, all with informative visual and verbal feedback. • From the watch face, tap on the Thermo Watch complication to open the app. Spin the Digital Crown, or Swipe up/down to adjust the temperature. You can start adjusting the moment the app opens. • On your iOS device you can see the thermostat info on the home screen widget. You can start/stop heating or cooling directly from the middle and large size widgets, or you can just open the app. Again, you can start adjusting the moment the controls appear. • From your Apple TV, open the app, and swipe up/down on the remote to change the temperate. The app is fully functional with the initial purchase. In-app purchases are available only for tipping the developer. The app will let you know with a chime and a tap, that the thermostat has received and applied your command. Monitor your Thermostats and Home/Away status right from the watch face, using complications that update in the background, without having to launch the app. You can use Siri on your iPhone, Watch, iPad, or HomePod to control any of your thermostats. Record phrases that make most sense to you, such as "Start Heating" or "Make it Cooler". If you have multiple thermostats you can control them individually, by saying for example "Start Heating Upstairs" or "Start Cooling the Living Room". Visit https://thermowatch.net/siri website for the detailed instructions of Siri operation. Set Geofence around your home to reliably set the Home and Away state when you come and go. The app supports multiple thermostats in multiple homes - just swipe left and right on your Watch screen to access them, or see them all at the same time in the iOS Widget and the app. Fahrenheit and Celsius are both supported. Beyond that, you can press and hold the Watch screen for additional functions, like switching to a heating or cooling mode, setting the away status, seeing the temperature sensors, or turning the fan on and off. While the app's minimalist looks betray the simplicity of its operation, what they don't show is the amount of planning, design, development and refinement that went into it, ensuring it becomes something that is enjoyable to use and experience. Thermo Watch does not collect any of your data. Your login information, thermostat settings, and any activity - all of it flows exclusively between your devices and Nest. Author of Thermo Watch does not receive any of it, at any point. This app and its developer are unaffiliated with Google Inc. or Google Nest. Nest is a trademark of Google Inc.

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.
