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

Stop switching to 123. Number Keys Please puts a real number row on top of your keyboard and hides a second character under every key, so numbers and symbols are always one tap or one swipe away. NUMBERS ON TOP • A full 1–0 number row above the letters, on iPhone and iPad • Prefer a shorter keyboard? Hide the row and swipe down on Q–P for 1–0 • Swipe down on any number for its symbol: ! @ # $ % ^ & * ( ) A SYMBOL UNDER EVERY KEY • Swipe down on a letter to type its symbol: brackets, quotes, slashes, currency and more • Make every key your own: pick up to 8 characters for any downward swipe, separately for English and Korean ENGLISH + 한국어 • Standard 두벌식 Hangul with compound vowels, double consonants and jamo-by-jamo delete • Hold the space bar to switch languages • Autocorrect and word suggestions in both languages, with one-tap undo LOW LAG TYPING • Median processing time in our typing engine benchmark: 0.4 ms for English and 0.2 ms for Korean (measured on a Mac; results vary by device) • Keys respond the moment your finger lands • Spell-checking runs in the background, so it never blocks a key EVERYTHING YOU EXPECT FROM A KEYBOARD • Shift, caps lock, repeating delete, two symbol pages and a smart return key • Slide the space bar to move the cursor precisely • Search more than 3,900 emoji in English or Korean, fully offline, with skin tones and recents • Optional haptics and key sounds THEMES • Classic is included and follows the light or dark keyboard iOS shows in each app • Liquid Glass, an optional one-time unlock, gives you translucent keys that swell, glow and spring back with every tap (iOS 26 or later) PRIVATE BY DESIGN • The keyboard never connects to the internet. Nothing you type is sent anywhere. • Dictionaries (8,000+ words each for English and Korean), autocorrect, suggestions and emoji search all live on your device • No analytics, no accounts, no typing data collected • Full Access is optional. It lets the app share your settings and purchased theme with the keyboard and enables optional key sounds. Without it, every typing feature still works. Try it before you install it everywhere: the app has a typing playground and a typing tester with poems and short stories to practice on. To get started, open Settings → General → Keyboard → Keyboards → Add New Keyboard and choose Number Keys Please.

Opportunities

AI-GENERATED OPPORTUNITY HYPOTHESES

These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.

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.
