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

Based on the legendary XPAN with its unique cinematic panoramic 65x24 images, XP4N turns any scene into a movie set; every shot into a movie still. - Shoot in the amazing 65:24 cinematic aspect ratio - Simulate 8 distinct film types (some inspired by popular film types, such as Cinestill 800T) - NO ADS, NO SUBSCRIPTIONS, NO IN-APP-PURCHASES! - Use all available lenses - Haptic and visual feedback when taking pictures - Use volume up key as shutter button - EV compensation by swiping - Access to the high-resolution sensor (if available and enabled in settings) - Option to save as lossless HEIF files - Saves EXIF and GPS data in photos This app is designed to simulate the cinematic qualities of the XPAN, including emulation of 8 distinct film stocks that are often paired with this camera: NIGHT MODE Based on the Cinestill 800T film character with its moody teal cast and signature "halation" (red halos) around bright spots in the image. BALANCED MODE Inspired by Vision3 250D film stock, with its versatile personality and typical Hollywood-style color and contrast curves. DAYLIGHT MODE Based on the popular Portra 400 film; soft and warm hues and moderate contrast profile. Great for skin tones and dreamy landscapes. GRITTY MODE Inspired by the Lomography Metropolis film, which adds a "bleached" look that is reminiscent of gritty 90s movies. BLACK & WHITE MODES Following the characteristics black & white films, one mode offers a punchy and contrasty B&W style, while the other is soft and dreamy. NEON NIGHT (NEW) Enhances bright spots in night photos and adds vibrant, saturated glows for a "cyberpunk" vibe ETHEREAL (NEW) Classic soft focus mode, without the need to put grease on your lens! XP4N is consciously made to be the ultimate one-trick-pony. A point and shoot camera with only a single button: the shutter button. The internal image processing engine does the rest, based on your preferred film mode setting. (so don't expect deep camera controls... ;-). The resulting images are carefully tuned to have the pleasant silky quality of film and to get away from the oversharpened, hyper-punchy look typical of today's digital cameras.

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.
