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

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

#1 must-have app for quickly and easily adding scrolling credits like you see in professional movies and TV shows to the beginning or ending of your videos. Also great for adding scrolling text to TikTok, Instagram, documentaries, sales, Facebook ads, and informational videos. ​ ​ CHECK OUT THESE PRO FEATURES: • Designed specifically to do scrolling credits! • Powerful, yet super easy to use--no learning curve! • Scroll credits over a flat background image or even video footage! • Supports one or two-column credits, just like the pros! • Easily add Headings to sections of credits! • Control font style, size, color, and scrolling speed! • Supports multiple SD/HD resolutions, including: SD 360p, HD 720p, HD 1080p and even Ultra HD 4K! • Supports multiple Aspect Ratios, including: 1:1, 4:3, 16:9 (landscape), 9:16 (portrait), and 2:1 (18:9). • Great for TikTok, Instagram or Facebook videos by using the 1:1 (square) or 9:16 (portrait) Aspect Ratios! • Smooth, non-jerky scrolling! • Includes dozens of HD backgrounds to choose from or upload your own! • Includes several "seamless" video loops (fire burning, flag waving, etc.) for motion-rich credits, or upload your own video footage! • Chroma Key "green screen" support! • Save and manage "projects," no need to start over to make a change! • Supports ALL devices (all sized iPhones and iPads)! ___________________________________________ HOW IT WORKS... ​ 1. Choose from the dozens of backgrounds provided by the app (a solid color, a gradient color, an image, a "seamless" video loop, or a "green-screen" chroma key), or upload your own background image or video. ​ 2. Enter the text you want to have scroll over the background you've selected. You can even use headings or two columns for your credits, just like the pros. ​ 3. Preview what your scrolling credits will look like, adjusting the scrolling speed, aspect ratio, and the font style, color, and size. 4. When you're happy with how everything looks, the app will render and save an HD video clip to your device's Photo Library (Camera Roll). 5. Optionally, you can use iMovie or other video editing software, import the credits video clip, and drag it to where you want it to play in your movie (such as at the end for closing credits). ___________________________________________ Here are all the sizes supported for each of the different aspect ratios: ====== 1:1 ====== SD 360p (360 x 360) HD 720p (720 x 720) HD 1080p (1080 x 1080) Ultra HD 4K (2160 x 2160) ====== 4:3 ====== SD 360p (480 x 360) HD 720p (960 x 720) HD 1080p (1440 x 1080) Ultra HD 4K (2880 x 2160) ====== 16:9 (landscape) ====== SD 360p (640 x 360) HD 720p (1280 x 720) HD 1080p (1920 x 1080) Ultra HD 4K (3840 x 2160) ====== 9:16 (portrait) ====== SD 360p (360 x 640) HD 720p (720 x 1280) HD 1080p (1080 x 1920) Ultra HD 4K (2160 x 3840) ====== 2:1 (18:9) ====== SD 360p (720 x 360) HD 720p (1440 x 720) HD 1080p (2160 x 1080) Ultra HD 4K (4320 x 2160) ___________________________________________ Need help?

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.
