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.

Put photos on your home screen using widgets. It also works great with StandBy. Create as many photo widgets as you like with one or more photos per widget. If you choose more than one photo, it will change photos on a time interval (which can be customized in the settings). Each widget can have separate photos. You can also show photos from an album in your photo library. ■ Features - Widgets with a single photo. - Widgets with multiple photos that change on an interval (slideshow). - Widgets showing photos from an album in your photo library (slideshow). - Three widget sizes. - Import photos from the photo library or the file system. - Tapping a widget can either show a larger preview of the photo, open a URL, or run a shortcut. - The “Album” widget has a setting to show a random photo only from the most recent `n` photos in the album, where `n` is the number you choose. ■ How it works First, decide whether you want to select the individual photos to show (1) or just choose an existing album from your photo library (2). 1. Add photos to the app which you can later choose from in a widget. Then add the “Photo Widget” widget with the “Photos” type and edit the widget to pick the photos to show. 2. Add the “Photo Widget” widget with the “Album” type and edit it to choose the album. ■ Limitation If you make two or more widgets of the same size where all of them are set to show all the photos or the same album, they will show photos in the same order. This is a limitation in the iOS widget system. You can work around this by giving the widgets unique names in the widget configuration. ■ Tip If you have a widget that cycles between photos and you want to force it to skip to the next photo, long-press the widget, select “Edit Widget”, and then close the edit view. The widget should now have a new photo. ■ FAQ 〉 How do I add a widget to the home screen? When on the home screen, long-press on the background (not on any icons), press the top-left “+” button, and select “Photo Widget”. 〉 How do I edit a widget? When on the home screen, long-press on the widget, and select “Edit Widget”. 〉 Why can I only add 100 photos to the app? This is because of a technical limitation in the iOS widget system. Hopefully, it can be increased in the future. It should be enough for most users though. If you use the “Album” widget, there’s no limit to the number of photos. 〉 How can I hide the name of the app shown below the widget? This is not possible. App developers have no way to hide it. 〉 How is this different from the built-in “Photos” widget? The built-in widget only shows photos from “Memories” and “Featured Photos” in your photo library. There is no way to customize it or pick the photos to be shown. 〉 Can I show an animated GIF in a widget? This is not possible.

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.
