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 Original Binoculars App and Highest Rated on the App Store with 32X Telephoto Zoom. This is the REAL THING with true 32x Photo-Quality Zoom and one-tap access to Satellite Aerial View of your location. Say goodbye to grainy zoomed pictures and say hello to the original Binoculars app for iOS. Binoculars by i4software is the ONLY Binoculars app on the app store that uses the full-sensor resolution of your iOS device to deliver the very best possible real-time zoom enlargement with stabilization. See the ratings and reviews for yourself. Other apps simply blow up the video preview without active stabilization resulting in terrible picture quality. Binoculars actually processes the full resolution photo sensor as fast as possible and then crops in on that full resolution photo image resulting in a much higher quality enlargement and a much more useful image. Why pack binoculars when they can now be a part of your phone? Zoom in up to 32x (on latest iOS devices with Telephoto Lens) and up to 16x on older devices. For a closer look at nature, sporting events, or someone in the distance use our digital binoculars for high-resolution photo or video while in extreme zoom mode. From i4software, creators of Vizzywig, Flashlight and Fast Camera! • Binoculars incorporates GPS technology and displays your location on the map, shows your latitude and longitude coordinates, and remembers the exact location of your pictures. • Binoculars’ simple user-interface makes it fast and easy to use for all ages. • Includes Google Cardboard mode in landscape orientation.

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.
