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.

A participant merely thinks of an image. Seconds later, you reveal exactly what they are thinking. Your participant can either think of any image entirely in their mind within a category… or freely focus on an image from your gallery. No writing. No typing. No awkward procedure. No AI and no internet connection required during performance. Focus is a professional performance system built for magicians and mentalists, designed to create impossible thought-reading demonstrations using a completely natural photo-gallery. “This has become a go-to for me. It’s incredibly user-friendly to perform, and the reactions I get are absolutely insane.” — Joe Bainbridge Unlike many digital effects, Focus is built to feel casual, organic, and genuinely natural in performance. The interface mirrors a real photo gallery, allowing the experience to unfold without suspicious handling, strange processes, or awkward procedure. Whether your participant merely thinks of an image in their mind or freely focuses on one from your gallery, the thought remains completely hidden. Use your own photographs, create custom galleries, and reveal thoughts in the way that best suits your performance style. Focus comes ready to perform with a built-in “Who Is It?” gallery, allowing you to start performing immediately straight out of the box. Built for real-world performance with instant reset, flexible handling options, optional smart watch notifications, and completely offline capability. Perfect for close-up, walkaround, social media, casual performances, content creators, and professional magic and mentalism routines. FEATURES • Create custom image libraries for different routines. • Use your own photos from your gallery, files, or folders. • Perform using either a freely thought-of image or a target gallery. • Comes ready to perform with a built-in “Who Is It?” gallery. • No AI used at any point in performance. • No internet signal required during performance. • Choose different reveal modes for each routine. • Instant reset between performances. • Flexible handling options for different performing styles. • Optional notification system for compatible smart watches. • Familiar gallery interface that feels natural and unforced. • Fast, reliable, practical, and performance tested. REVEAL MODES Focus is designed to reveal your participant’s thought in any way you want. If you simply want to secretly discover what your participant is thinking and reveal it later in your own way, Focus allows you to do that in seconds. However, Focus also includes several powerful built-in reveal systems… Live Peek Secretly obtain the thought-of information with invisible handling. Reveal it naturally away from the screen, or also receive the information through an optional notification system on your phone or compatible watch. Mosaic Zoom out from a single image and watch the entire gallery visually transform into a giant mosaic revealing the participant’s exact thought. Falling Tiles The gallery dramatically shatters apart tile by tile, exposing the single image the participant is merely thinking of beneath it. Polarise Shake the device and watch the gallery visually morph and blend into one clear image, the exact image held in the participant’s mind. Recently Added Sometimes the strongest methods are the simplest. Quietly identify the participant’s image using a deceptively innocent reveal process that feels completely genuine and impossible to backtrack. Turnover Appear to arrive at the wrong conclusion before the image unexpectedly transforms, revealing that you knew the participant’s thought all along. Focus is designed for performers who want mentalism that feels impossible, natural, fast, and real.

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.
