Generating… usually about a minute.
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.

Artist's Viewfinder assists the filmmaker or still photographer in exploring different places and angles to find the optimal placement for the camera, and to second-guess compositions. By simulating real camera and lens combinations it allows you to visualize what you are going to shoot without actually setting up the camera. And it's also a great tool to train yourself to see. Handles Like Your Camera Exposure compensation. Auto-focus lock. AF confirmation beep. A Quick Control Screen for accessing frequently needed functions. Smart Function Keys. Shutter release via the Volume buttons. We designed the Mark II so that you could feel at home the moment you start working with it. And because it also saves high resolution photos, you can even use it as a regular camera. Visualize the Grand Landscape Paired with a 0.5x-class super-wide converter lens*, the Mark II becomes an indispensable tool for landscape and architecture photographers. The combination can simulate super-wide lenses up to around 16mm on the full-frame 35mm format. Or you can use it to compose super-wide stitched images. The Mark II even removes distortion present in the wide converter lens — in real time. * FOR THE LIST OF SUPPORTED CONVERTER/DEVICE COMBINATIONS PLEASE VISIT: https://www.artistsviewfinder.com/tech-specs/ When There's No Need for Color In black & white mode Artist's Viewfinder shows just the luminance information of the scene, making it easier to explore tonal structures and simulate what a black & white photograph will look like. Taking it a step further, the optional dark and neutral toolbar theme ensures that colors from the app doesn't interfere with your composition. Unprecedented Simulation Flexibility The Mark II leverages our extensive Viewfinder Camera Database, containing more than 800 still and motion picture cameras, 180 medium/large format backs and countless lenses — incorporating real lens data for ALPA, Hartblei, Hasselblad, Leica, Rodenstock, Schneider and Zeiss glass. And you can define your own cameras and lenses when you need something special for the job. Does What Optical Viewfinders Can't Even Dream Of Artist's Viewfinder stores location and simulation metadata with the pictures, allowing you to evaluate results of a location scout later on your computer. Or you can send the information off to the rest of the crew or to a rental house, right from the app. It also records a standard GPX format track log, alleviating the need for a separate logging device.

To explore the complete list of features, please visit: https://www.artistsviewfinder.com/features/ Written by the author of the app, The Viewfinder Handbook is the ultimate source of information about the Mark II. Way more than a user manual, this free eBook not only walks you through the ins and outs of the app, but also provides conceptual background, insights and useful hands-on advice.

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.
