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.

Ready for exotic birds? iBird Hawaii and Palau is the only 100% complete app guide to birds of the Hawaiian Islands as well as the environmentally sensitive island nation of Palau. The app, which contains 228 species of Hawaiian birds and 169 species of Palauan birds offers all the features that contribute to making iBird the most popular birding app in the world. Like our top of the line iBird Ultimate app, iBird Hawaii and Palau offers the popular Birds Around Me (BAM) GPS feature as well as the Percevia™ Smart Search feature. More Details of What’s New: bit.ly/ibird-whatsnew In 2008 iBird broke new ground as it turned the iPhone into a field guide app that identifies birds and plays their songs. Featured in Apple’s television commercials, it started a revolution that made iBird the most respected birding app in the world. ** NOTE If you would like to try out iBird at no expense, check the newly released iBird LITE Free Guide to Birds of North America. It contains all the features of paid iBird Ultimate, but includes just 50 species. And it’s completely FREE. ** Whether you are an experienced birder or a beginner, iBird Hawaii and Palau is the most authoritative guide to these exotic birds. Features ■ Separate databases for Hawaii and Palau allow doing independent searching and identification as well as separate species accounts and song libraries. ■ Birds Around Me (BAM) narrows the species being searched to just those found at your GPS location, within a radius and season you specify. ■ Percevia™ intelligent search is a patented algorithm that guarantees you will only choose search attributes that narrow the matched list of birds. ■ iBird now takes advantage of the high-resolution retina displays of the iPhone and iPad so the screen shows more information than ever. ■ Contains the latest 2017 AOU checklists. ■ Splits History. See what birds were renamed, split into different species or lumped together for 2014, 2015 and 2016. ■ View all birds by head which makes identification easier. ■ Back up and sync favorites and notes with iCloud and share with all your devices and your friends. Popular Features ■ ‘Birds Around Me’ narrows the search list to just those birds centered on your GPS location, within a specified radius and a specific season. ■ The patented Percevia™ intelligent search prevents you from making the wrong choice when searching for your bird. ■ The only birding app that includes both Illustrations and Photos. ■ Every species is shown perched and in flight and most show major seasonal, age and male/female variations. ■ Identify 397 species of both native and rare Hawaiian and Palauan birds. ■ Save multiple personal species lists and your sightings in Notes which can be backed up and synced in iCloud. ■ Includes hundreds of carefully selected and edited sound recordings from the Xeno-Canto Community of bird song recordists. ■ iBird’s icon-driven visual search engine, with 35 attributes, enables you to identify birds using shape, color, location, habitat, head pattern, flight pattern, bill shape, length and much more. ■ Search by common name, Latin name and even band code. ■ Comprehensive seasonal and migratory range maps include subspecies. ■ The Conservation Status search attribute lets you filter birds by 6 threat levels including Least Concern, Near Threatened, Vulnerable, Endangered, Critically Endangered and Extinct in the Wild. The standard is maintained by Birdlife International and is called the IUCN Red List. We invite all users to share their comments and ideas on our forum at www.whatbird.com/forum.

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.
