App Overview
Smart Binoculars - 60X Zoom
Why smart? Because the binoculars try to make the image a little more accurate and lower the blur a bit when the digital zoom approaches 60X zoom than if you zoom in to the 60x with normal zoom

Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
Why smart? Because the binoculars try to make the image a little more accurate and lower the blur a bit when the digital zoom approaches 60X zoom than if you zoom in to the 60x with normal zoom. This is particularly noticeable when it's a clear day. The magnification quality will depend entirely on your camera. Binoculars can come in handy when you are in a hopeless situation when traveling, for example, and you simply don’t have a real device to take a closer look and capture an image of something. Although this will not replace the real thing, binoculars are convenient to have as a last resort. Then of course, you can save photos of things that you find around the world. - Up to 60X Digital Zoom - Manual focus - Manual exposure - Auto focus - Auto exposure - Photos is saving in your iPhone gallery

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

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.
