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.

PhotInfo is an app to view, edit, and manage photo metadata - such as location, camera info, date, time, and more - right from your iPhone, iPad, or Mac. # Why PhotInfo Every digital photo contains more than just pixels - it holds hidden metadata like shutter speed, camera model, ISO, focal length, and even GPS location. PhotInfo gives you full access to this information, letting you explore, understand, and take control of what your photos say about you. Whether you want to edit or remove metadata for privacy, correct missing or inaccurate info, or simply learn more about how your photos were taken, PhotInfo makes it easy. It's a powerful tool for photographers, teachers, and anyone who wants to get more from their images - or just keep their photo library tidy. Real users include photography instructors and enthusiasts who use PhotInfo to improve their technique or teach others. # What makes this app unique • Detailed metadata access (Exif, Tiff, IPTC...) • Human-readable + raw formats • Smart photo navigation and album browsing • The IPTC metadata editor with a template • Actively maintained since 2013 • Lightweight: less than 4MB # Features With PhotInfo you can: • View all the tags (Exif, Tiff, IPTC, etc.) from a picture: in raw or in human readable format • Display an image with the main tags and the map of the location in a single view • Share an image with or without tags • Copy the key data or the content of individual tags • Share all the tags in raw or in human readable format or as a JSON • Edit or create a copy of the image with modified tags • Modify IPTC tags using values saved in a template • Create a copy of the image with the minimum content of info in the tags (related to image data structure, such as the image size, resolution and • orientation) • Duplicate a photo with a custom name • Edit a batch of photos • See where the photo was taken, in different ways (map, address, coordinate) • Favorite or delete a photo • Quickly scroll through the albums of your iOS device • Look at different pictures in burst photos (iOS only) • See and share associated files: such as original image for edited photos or video for live ones • See advanced image payloads, such as Semantic Segmentation Mattes and HDR Gain Map data • No data is shared; only photo coordinates are sent to Apple's servers to retrieve a human-readable address - and nothing else leaves your device • View the tags directly from other apps with the PhotInfo's Extension PhotInfo app is in constant development, so new features will be added soon.

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.
