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.

It’s a complete game-changer that takes what used to be possible with expensive and complicated systems and makes it a reality for everyone” https://thepegeek.com/2016/03/raising-bar-bam-video-delay/ [australiancurriculumtfel.edublogs.org] “The app has great potential to be used on a regular basis in physical education classes as a formative assessment tool.” http://australiancurriculumtfel.edublogs.org/2015/11/11/formative-assessment-using-bam-video-delay-app-in-pe/ USER REVIEWS: By Kbone2000 5/5 Great app! Every coach needs this app. Immediate feedback for players and a great way for self analysis. By James McDermott 5/5 Great app! Works for what I need, nice that you can have a delay rather than asking someone to record each time. By awholelottatry 5/5 A great technical training tool for sport and fitness This is exactly what I was looking for! Needed it to perfect technique in Crossfit Olympic lifting. Every technical sport could use this valuable tool. DESCRIPTION: Ever wanted to learn a new move? Be it for professional dancing, gymnastics, golf, basketball, tennis, martial arts, breakdance, strike a pose or other use. A mirror is nice but it's hard to move and look the same time, sometimes even impossible when not facing forward. A video camera is OK but it is a hassle with all the start, stop, rewind, positioning and other. So in the end you don't use either, give up on learning something new and move on with your life. "Bust a Move Video Delay" solves these problems. It gives you an easy to use tool with quick feedback. You see what you just did, so you can correct it, try again, look again, correct ... and so on. Also, after the initial setup, no interaction is needed so you can focus on training without any distractions. SO WHAT DOES A “VIDEO DELAY” DO ? It continuously shows you what just happened seconds ago. There is no alternating record or play phase, just continuous playback but with a given delay. This way you get fast and easy accessible video feedback. Also no tapping, rewinding or other interactions are needed. Once set up it works hands free so you can focus on your moves. Now there are just two easy steps: 1. BUST A MOVE (do what you want to learn) 2. LOOK & LEARN (see what you just did and what's wrong) This way you get instantaneous feedback so you can quickly learn on your mistakes and get better in no time. FEATURES: - "hands free" continuous playback but with a delay - up to Full HD at 30 fps and HD at 60 fps - universal app for both iPhone/iPod and iPad - delays from 1 second up to 6 minutes - uses device memory instead of its flash drive - up to 4 independent views so you can see yourself 4 times in a row - slow motion and pause to analyse the video - export as video - AirPlay and HDMI TV cable support - auto hiding interface controls - "Live View" for easy positioning of the camera and setup - front to rear camera switch - horizontal flip - x2 Zoom with panning - exposure and focus setting - and a manual, just in case

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.
