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.

GR Snap is the iOS companion app for Ricoh GR cameras. Browse photos on your camera, transfer full-resolution originals, add location data as you shoot, create framed images for sharing, and take still photos remotely from iPhone or iPad. Main features - Wireless transfer: JPG, DNG, and MOV formats. Single or batch download, saved directly to your Photos library. - Geotagging: send your device's location to the camera over Bluetooth as you shoot. Route history stays on your device and can repair missing locations after photos are downloaded. - Share styles: choose a canvas ratio, photo frame, brand overlay, camera model, and shot info before sharing. You can always share the original files unchanged. - Remote still-photo shooting: use your device as the viewfinder, compose, focus, and release the shutter from a distance. - Lock Screen and Dynamic Island progress: see download status while the app is in the background, and get a notification when each one finishes. - Camera parameter sync: aperture, shutter speed, and ISO update in real time, and can be changed from the app. - Batch select: swipe to select multiple photos, then download or share them all at once. - Pinch to view at actual size. Compatible cameras Ricoh GR III, GR IIIx (including the HDF Edition), and GR IV support wireless transfer, Bluetooth wake, geotagging, live view, and remote still-photo shooting. GR II supports manual Wi-Fi transfer only; Bluetooth wake, live view, and remote shooting are unavailable. It cannot receive your location while you shoot, but GR Snap still records your route on the phone and adds the missing locations when you download over Wi-Fi. Works without upgrading your camera firmware. Privacy Photos and saved routes stay on your devices. Location data is sent only to your camera, and photos are not sent to a server. The app does not collect information that identifies you. Interface languages English, German, Japanese, Korean, Simplified Chinese, Traditional Chinese, and Spanish.

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.
