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

Pantograph gives you insights into your travels—and the whole transit system—like no app before it. Every active bus, train, ferry, and streetcar from supported agencies is visible on one map, empowering you with information only before seen by dispatchers. Plus, when you know your stop, see realtime departure estimates for every route arriving. Pantograph is named after the part of an electric train that connects it to the overhead electrical wire—just likes it connects you vital information about the transit network. Key features: • Identify at a glance areas where vehicles across all routes are getting delayed. • View statistics for all vehicles on the map, including how many are on-time, running later than usual, currently serving each route, and more. • View current vehicle passenger load and capacity (supported agencies only). • See route and stop schedules with realtime updates based on current conditions, and save favorite stops for later. • Customize what data is displayed on vehicle icons. • See an up-to-the-minute report on how many trips are being missed each day. • Add widgets showing the status of a selection of routes. • Learn exactly which bus, train, or ferry is serving each trip, as well as its model information—helping you get a more enjoyable ride. • View the full set of trips each vehicle will be serving today, as well as each trip's full stop schedule. • Browse the daily timetables for each route, plus use an advanced Block Timeline to see vehicle schedules. • Explore the full assignment history for every route and vehicle, helping you learn what routes get certain kinds of buses, track down the bus you left your headphones on, follow new additions to the fleet, and more. With a Pantograph Pro subscription, you can also: • Take advantage of a powerful filtering system, allowing you to show vehicles only on certain routes, from certain agencies, and more. • See how "normal" a specific bus's current schedule delay is, gaining further insight on current system performance. • Customize the app, such as changing the app icon to a variety of different color schemes, or controlling which buttons appear in the action bar. Currently available in: • Greater Puget Sound (10 agencies: King County Metro, Sound Transit, Community Transit, Pierce Transit, Intercity Transit, Everett Transit, Seattle Streetcar, Whatcom Transportation Authority, Skagit, Washington State Ferries) • Eastern Washington (Spokane, Pullman) • Vancouver, BC (TransLink) • Montréal, QC (STM, exo) • Portland, McMinnville, Eugene, and Corvallis, OR (TriMet, Yamhill County Transit, Lane Transit District, Corvallis Transit System, Benton Area Transit) • Los Angeles and Southern California (26 agencies: LA Metro, Foothill Transit, Orange County, San Diego MTS, Torrance, more) • The San Francisco Bay Area (24 agencies: SF Muni, AC Transit, SamTrans, VTA, Caltrain, Golden Gate Transit, Tri Delta Transit, Wheels, Sonoma Marin Area Rail Transit, more) • Central CA (FAX, Merced, GET Bus, StanRTA, more) • Washington, DC and Baltimore, MD (8 agencies: WMATA, MTA Maryland, Arlington, Fairfax Connector, Virginia Railway Express, DASH, more) • Boston, MA (MBTA) • Providence, RI (RIPTA) • Philadelphia, PA (SEPTA) • Minneapolis, MN (9 agencies: Metro Transit, Met Council, Maple Grove, MVTA, more) • Denver and Boulder, CO (RTD, Via, Bustang) • Islands of O'ahu, Maui, and Kaua'i; Hawai'i • ...with more on the way!

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.
