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

Loop is a deep-focus timer designed for people who care about flow, craft, and discipline. A minimal interface, subtle haptics, and customizable session lengths help you get into focused work quickly—without the noise, badges, or gamification of typical productivity apps. Whether you're working through a long sprint, training attention, studying, writing, meditating, or simply trying to stay off your phone, Loop gives you a clean, intentional space to focus. Why Loop is different Minimal, elegant design — A distraction-free UI crafted for clarity and calm. Loop mode (background repetition) — Sessions automatically repeat so you can stay in flow without interruptions. Customizable timing — Set your focus, break, and long-break durations to match your rhythm. Works with screen off — Save battery and stay locked-in while the timer continues in the background. Precise haptics — Gentle taps notify you without breaking your concentration. No accounts, no ads, no clutter — Designed for people who want focus, not another feed. Perfect for Deep work Studying Writing & coding Meditation / breathwork timing Pomodoro-style sessions Creative sessions Anyone building discipline or reducing screen time Loop helps you create space for your best work. No friction. No dopamine traps. Just focus. Privacy & Respect Loop collects zero data. Your focus belongs to you.

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.
