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

At DuckDuckGo, we believe the best way to protect your personal information from hackers, scammers, and privacy-invasive companies is to stop it from being collected at all. That's why millions of people choose DuckDuckGo over Chrome and other browsers to search and browse online. Our built-in search engine is like Google but never tracks your searches. Our browser blocks YouTube ads, invasive web ads, and cookie pop-ups, reducing distractions and helping to stop other companies from collecting your data. While our optional integrated AI features, Search Assist and Duck.ai, are private and never use your data to train AI. Oh, and our browser is free. We make money from privacy-respecting search ads, not by exploiting your data. Take back control of your personal information with the browser designed for data protection, not data collection. FEATURE HIGHLIGHTS Protect Your Searches by Default: DuckDuckGo Search comes built-in, so you can easily search online without being tracked.  Shield Your Browsing History: Our 3rd-Party Tracker Loading Protection blocks most trackers before they load, greatly exceeding what most popular browsers offer by default.  Chat Privately With AI: Duck.ai lets you have private conversations with 3rd-party AI models, anonymized by us and never used to train AI. Secure Your Email (Optional): Use Email Protection to block most email trackers and hide your existing email address with @duck.com addresses.   Block Ads: Our browser blocks YouTube Ads, and stops invasive trackers from loading on sites, effectively eliminating targeted ads. Automatically Enforce Encryption: Shield your data from network and Wi-Fi snoopers by forcing many sites to use an HTTPS connection.  Escape Fingerprinting: Make it harder for companies to create a unique identifier for you by blocking attempts to combine info about your browser and device.  Sync and Back Up Securely (Optional): Sync encrypted bookmarks and passwords across your devices. Clear your tabs and browsing data in a flash with the Fire Button. Banish cookie pop-ups and automatically set your preferences to minimize cookies and maximize privacy. And many more protections not available on most browsers, even in private browsing mode, including protection from link tracking, Global Privacy Control (GPC), and more. DUCKDUCKGO SUBSCRIPTION Subscribers get • Our VPN: Secure your connection on up to 5 devices.     • Access to advanced AI Models in Duck.ai: Chat privately with AI models built for complex tasks. • Personal Information Removal: Find and remove personal info from sites that store and sell it.   • Identity Theft Restoration: If your identity is stolen, we’ll help restore it.   DuckDuckGo Subscription Pricing & Terms   Payment will be charged automatically to your Apple Account until you cancel, which you can do in app settings. You have the option to provide an email address to activate your subscription on other devices, and we will only use that email address to verify your subscription.

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.
