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
Focus with bold design, not distractions. Focushaus is a Pomodoro timer inspired by the Bauhaus: strong colors, clean geometry, and huge, easy-to-read numbers. Work in focused 25-minute sessions, take short breaks between them, and enjoy a longer break after every four. It's the proven way to get more done with less mental fatigue. YOUR TIMER, EVERYWHERE • Live Activities show the countdown on your Lock Screen, in the Dynamic Island, and in StandBy. • In StandBy, the timer goes full screen with huge Bauhaus numbers you can read from across the room. • Start your next session or break, or reset the timer, right from the Lock Screen. • Cycle dots show where you are in your set of four. • Glance at the timer on Apple Watch in the Smart Stack. • The timer keeps running even if iOS closes the app in the background. STREAK WIDGETS • Focus Streak widgets for your Home Screen, Lock Screen, and StandBy. • See your current streak, today's sessions, and the last 7 days at a glance. • Start a focus session with one tap from the medium widget. BUILT FOR iPHONE DUO AND EVERY SCREEN • Unfold your iPhone Duo to see your timer and stats side by side. • Stand it up half-folded like a tent, and the numbers turn so you can read them from your desk. • Lock it in the tent pose and StandBy turns it into a full-screen focus clock. • A full-screen timer on iPhone and iPad, in any orientation on iPad. STAY MOTIVATED • More than 50 achievements for streaks, milestones, full cycles, early mornings, late nights, weekends, seasons, and comebacks. • Daily streaks that keep you coming back. • Stats that show your focus time day by day and week by week. THOUGHTFUL DETAILS • Gentle notifications when a session or break ends. • Old "session finished" alerts clear themselves once you start again. • Haptic feedback for a satisfying, tactile feel. • Light and dark appearance. HOW IT WORKS 1. Start a 25-minute focus session. 2. Work until the timer ends. 3. Take a short break. 4. After four sessions, enjoy a long break. Whether you're studying, writing, coding, or tackling any task that needs real attention, Focushaus gives your day a simple, beautiful rhythm.

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.
