Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
API Widgets brings live data to your home screen. Connect any webhook or JSON API and display the information that matters most in beautiful, customizable iOS widgets - no coding required. WORKS WITH ANY API If it returns JSON, you can display it. Point a widget at any webhook or REST endpoint and choose how to visualize the response. Works great with automation platforms like n8n, Zapier, Make, and Pipedream, as well as your own backends and public APIs. MULTIPLE VISUALIZATION OPTIONS • Tables - Structured data in clean, readable rows • Pie Charts - Proportions and distributions at a glance • Bar Charts - Compare values across categories • Text - Simple values, messages, or status updates • Two-Column Layout - Side-by-side comparisons ALWAYS UP TO DATE Widgets refresh automatically in the background so your data stays current without lifting a finger. POWERFUL DATA TRANSFORMATION Use expressions to extract and format exactly the fields you need from complex API responses. Drill into nested JSON, format numbers and dates, and shape the output to fit the widget - all without writing code. PRIVACY FOCUSED Your data stays on your device. API Widgets connects directly to your endpoints - no third-party servers, no accounts, no tracking, no data collection. IDEAL USE CASES • Business metrics and KPIs • Server, service, and uptime status • IoT and home automation sensor readings • Stock, crypto, and currency prices • Personal dashboards and trackers • Outputs from automation tools (n8n, Zapier, Make, etc.) • Sports scores, weather, transit, or anything else with an API Get started in minutes: add a widget, paste your endpoint URL, choose a visualization, and your data appears on your home screen.

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.

BUILD KIT DIFFICULTY
Intermediate
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.
