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.

* Special Offer Price * NDICam is the original NDI iOS camera built by the world's leading NDI broadcast infrastructure developers - Sienna. Mature and feature rich, uniquely with both Full NDI and NDI HX3 modes. The NDI (Network Device Interface) protocol connects to professional vision mixers and other devices, and delivers a high quality, low latency connection. NDICam is compatible with All TriCasters, VMix, Wirecast and hundreds of other professional IP video systems, software and hardware, which support NDI. - Simple to use - nothing to configure on your iOS device - Switch between front and rear cameras during broadcast - Auto Focus, AF Lock and Tap to Focus - Auto Exposure, AE Lock and Tap to Expose - Illumination light on/off - Audio Mute Control - Manual Naming of NDI Stream source - 4 quality / performance levels to suit your device and network, plus NDI HX Option - Pinch to zoom (where zoom is supported) - Auto-lens mode for multi-lens cameras - On screen live / preview tally plus optional use of camera flash as talent tally (with red gel cover). - Option to prevent iOS device sleep - Select 25FPS or 29.97FPS standard rate. - Choice of Full NDI or NDI HX3 compression modes (HX2 at 2 to 20 mBit, plus HX3 Ultra) - Rotation support for Portrait or Landscape Video Modes. Front and Rear cameras can be selected at the touch of a button and NDICam features a 4 position quality vs frame rate slider to deliver optimum video suited to the quality of your wifi connection and your iPhone's processing performance. Depending on your iOS device, compression mode selected and Wifi network performance NDICam supports up to 1080 full HD resolution. Control of flashlight, touch to focus, focus lock, pinch to zoom and audio enable are also included. You can even use the phone's torch as a Tally Light, by covering it with a red gel. Note: Depending on the performance of your iOS device and your WIFI network, you may not see full frame rates when operating at maximum 1080 resolution with a full HD camera. Using HX3 mode will help if the bottleneck is your WIFI network. Note: NDI is a high bandwidth protocol designed for local area Gigabit networks. In order to see good results you will need a fast, uncontested wifi connection. If you see slow frame rates, try improving the wifi environment, with a better router, less interference, directional antenna or maybe switch to 5GHz if you are on 2.4GHz. . NB HX3 Ultra will use around 50mBits of bandwidth, so it's lower than full NDI, but still quite high. Use one of the lower bandwidth HX3 modes if your network connection is struggling. NDICam is also compatible with wired ethernet connections to iOS devices which can help deliver smooth video compared to a poor quality Wifi network. Good results have been seen with lightning to ethernet adaptors. You can specify an NDI discovery server in the application settings. Note that you will need to restart the app for any changes to take effect. Specifying a discovery server will disable the standard mDNS (Bonjour) advertisement for the NDI Cam source, so your iOS device must be able to reach the discovery server one the network. If you experience problems - delete the Discovery Server entry and restart the app. NB: NDI HX3 Ultra mode requires a recent NDI compatible receiver.

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.
