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
Web Video Caster® allows you to watch on your TV videos from your favorite websites including movies, TV shows, live streams of news, sports. SUPPORTED STREAMING DEVICES Web Video Caster® supports the most popular streaming devices, allowing your TV to stream videos directly from the web. • Google Cast (Chromecast, Android TV, Chromecast built-in) • DLNA devices like Xbox, Samsung TVs, LG TVs, etc. • Roku, Roku stick and Roku TVs • Apple TV 4 • Fire TV and Fire TV stick • PlayStation 4 - by using its web browser • Most web browsers by visiting http://cast2tv.app (PS4, Smart TVs, other consoles and set top boxes) *If you experience a compatibility issues, contact us and include the brand and model number. SUPPORTED MEDIA • HLS live streams in M3U8 format (Chromecast, most DLNA devices lack support for it) • Authenticated videos including movies and TV shows • MP4 videos • Live news and sports • Any HTML5 videos* *Your streaming device must be capable of decoding the video you are playing. Web Video Caster doesn't perform any video/audio decoding or transcoding. HOW IT WORKS Web Video Cast™ is a browser, which allows you to stream videos of movies, TV shows, and other media from the internet to a streaming device or smart tv. Web Video Caster grabs the video URL inside the web page, sends it to the streaming device (i.e. Chromecast or DLNA device), and then plays the video directly from the content provider. This ultimately saves your mobile device’s battery. It also detects subtitles on the web page. Web Video Cast™ does not host these videos. This is not a mirroring app. GET STARTED Follow these simple step-by-step instructions to start streaming: 1. Find a video online that you want to watch. 2. Make sure this video can play on mobile browsers without Flash. 3. Connect to your streaming device. 4. Play the video as you normally would. Or, click the play button on the toolbar. PREMIUM FEATURES** • No in-app advertising • Most visited sites • Bookmarks • Set homepage **This functionality does not apply universally to all streaming devices. LIMITATIONS & DISCLOSURES As with all apps, there are some limitations we are aware of and want you to know about up front. • We are in no way associated with any web media providers and we do not have control over the content they provide. • Web Video Caster does not support nor play Flash or FLV videos. • The app does not support tab casting, like the Chromecast extension for the PC web browser. • We cannot do anything to fix issues that arise on the server side (media content provider) such as failure to play or buffering, which is especially common during heavy load times and weekends. SHARE YOUR FEEDBACK We are committed to open communication with our users. Please contact us first with any questions or support issues before leaving a review. We will respond and address your concern promptly. Contact us through our website http://www.webvideocaster.com/contactForm

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.
