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

*** This mobile field guide includes all 492 bird species likely to be found on the islands of Trinidad & Tobago. This makes this app the one and only to date mobile bird guide to this region! The content is mainly derived from Bloomsbury's Helm Guide "Birds of Trinidad and Tobago". Covering 492 species with 1,200 superb illustrations and 972 songs and calls. All distinct plumages including all variations and subspecies are illustrated. *** The app's content is mainly based on the second edition of "Birds of Trinidad and Tobago" by Martyn Kenefick, Robin Restall and Floyd Hayes. Comprehensive descriptions for each species were taken from the renowned two volume reference work "Birds of Northern South America" by Robin Restall, Clemencia Rodner, and Miguel Lentino. The app also contains some species which haven't been recorded on T&T so far but are likely to be spotted if known what to look out for (some swallows and swifts). All of these are illustrated too. The creation of apps from the books is a co-production between Bloomsbury Plc and Sunbird Images. With over half a million downloads and over 100 apps published to date Sunbird Images became the true market leader in mobile field guides in recent years. SUNBIRD apps have been featured over 300 times by Apple in different countries, and appeared in many magazines, newspapers such as the Times, the Telegraph and described as "incredibly useful" by ITV's Seth Convey and "lovely" by Adam Vaughan of the Guardian. This app is part of the Sunbird Images BLUE LABEL series. Our BLUE LABEL series are top notch digital field guides which provide the most comprehensive data available for a region or taxon. They stand for completeness including even the very rare species and vagrants which have only been recorded once in a region. Even the rare species are illustrated and described in detail featured with a full species account. FEATURES: - Includes all 492 bird species of Trinidad and Tobago - Select species of each country separately - 1,200 illustrations show all subspecies + geographic, age and sex variants - Most advanced Compare Mode of any bird app - compare up to 16 species images / songs / maps - 972 bird songs and calls - Sonograms of all songs + details where songs were recorded - Detailed distribution maps of Northern South America down to subspecies level - Introduction contains detailed hints and links on bird watching on the islands - Create sighting lists and sort by place, date, group, and name - Automatically plots all birds on a map via GPS (editable) - Make notes for each bird spotted - A simple id key makes species identification easy - Sort and display species: A–Z, 6 different languages, taxonomic listing *** Ornithomedia writes: "Ergonomie agréable et claire" *** Choose between 6 bird name languages: English, Latin, Spanish, French, Dutch, German Narrow species down by foot colour, bill shape, tail length etc. leading to the bird searched for plus a choice of similar species. You can also look for fragments of a species name – the search for “finch“ shows all the species which include the word “finch“ in the species’ name. ***A graphically well-designed layout – easy to use with large lettering.*** Once downloaded no internet connection needed – just download the app and start birding! The app will be continuously developed further. All updates are free of charge. Visit our internet support site for more information www.sunbird.tv.

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.
