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

Reader Ultra is RSS the way it should be: fast, clean, and completely free of nonsense. No cluttered timelines. No ads dressed up as articles. No algorithm deciding what you see. Just your feeds, your folders, and a reading experience built for speed and focus — on iPhone, iPad, and Mac. GET STARTED IN SECONDS Fill your reader your way. Add feeds by hand, paste in your own feed URLs, import an existing OPML file to bring your whole library across in one step — or skip the setup entirely and pick from a specially curated selection of quality feeds to get you reading straight away. However you start, you're only a tap or two from your first article. FAST, FROM LAUNCH TO LAST ARTICLE Reader Ultra opens instantly and stays out of your way. Scrolling is smooth, articles load clean, and everything is designed to get you reading in seconds — not fighting a busy interface. A PRIVATE, HIGH-PERFORMANCE SYNC SERVICE Reader Ultra includes its own private RSS sync service — not a bolt-on, and not built on tracking. Your feeds and reading state sync across every device in real time, and it's fast: read an article on your Mac and it's already marked read on your iPhone; add a feed on your iPad and it appears everywhere in seconds. Silent background push keeps every device current without draining your battery, and the whole service is engineered for speed and reliability even with hundreds of feeds and thousands of articles. Sync is included at no extra cost — there's no separate account to juggle and nothing to configure. NATIVE ON EVERY PLATFORM, OPTIMISED FOR EACH Reader Ultra isn't a single app stretched to fit — it's built natively for iPhone, iPad, and Mac, and tuned for each one. On iPhone it's a fast, one-handed reader designed for quick sessions on the go. On iPad it takes full advantage of the larger canvas with multi-column layouts, split view, and keyboard support. On Mac it's a true desktop app with real keyboard shortcuts, resizable columns, and multiple windows — the polish Mac users expect. Whichever device you pick up, it feels like it was made for that device, because it was. FOLDERS, YOUR WAY Organise feeds into folders and make them yours — custom names, custom SF Symbol icons, and colours that help you find what you want at a glance. A tidy sidebar means less hunting and more reading. PERSONALISE EVERY DETAIL Reader Ultra is yours to shape. Choose from 20+ app icons and matching app accent colours to set the whole app's tone. Customise the sidebar to suit how you read — tailor the status tile, adjust the analytics tile, or hide the analytics tile entirely for a cleaner, more focused layout. Make it as informative or as minimal as you like. OPTIMISED SHARING Share the way you actually want to. Reader Ultra gives you clean, fast sharing to your favourite apps — the full article, the link, or a quick summary — with a share sheet that just works. SAFARI EXTENSION Subscribe straight from Safari. The extension finds every feed on the page — even the ones sites don't advertise — and hands it to Reader Ultra, ready to add. THOUGHTFUL, MODERN FEATURES • On-device article summaries powered by Apple Intelligence • Siri AI, Siri Shortcuts & App Intents — refresh feeds, find articles, and more, hands-free • Feed filtering — define keywords to filter out articles in individual feeds • Spotlight integration to jump straight to your articles • OPML import & export — bring your feeds in, take them anywhere • A clean reader view that strips clutter and blocks distracting content • Unread counts and badges that stay accurate across every device PRIVATE BY DESIGN Your reading is yours. Reader Ultra doesn't build an ad profile, doesn't track what you read, and doesn't get in your way. Whether you follow a handful of blogs or hundreds of news sources, Reader Ultra keeps everything fast, organised, and perfectly in sync. Download Reader Ultra and rediscover how good RSS can feel.

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.
