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

Can brewing coffee at home be both easy and delicious? Yes! Brew Timer helps you produce a consistently great cup of coffee by guiding you step-by-step through the brewing process. Start with one of the included brew recipes or add your own and tune it to perfection. Brew Timer works with you, no matter what you use to brew. Water mass, grind setting, total brew time — there's a lot to keep track of when dialing in your brews. That's why Brew Timer is packed with powerful features like grinder-specific settings, smart water adjustments, and an automatic brew journal. When you find your perfect cup, Brew Timer will help you repeat it. Brew a delicious cup of coffee every time with Brew Timer! — 28 Included Recipes — Aeropress (×5) Hario V60 (×4) Chemex (×3) Kalita Wave 155 (×2) Kalita Wave 185 (×2) Espresso (×2) Hario Switch (×2) Stagg [X] (×2) Stagg [XF] (×1) Clever Dripper (×1) French Press (×2) Siphon (×1) Tricolate (×1) Add your own! (×∞) — 36 Included Grinders — 1Zpresso Baratza Capresso Commandante Fellow Hario Helor Kinu Knock Niche Orphan Espresso Option-O Porlex Timemore Wilfa Add your own! — Coffee Tracking — Brew Timer comes with detailed coffee tracking built in. You can track everything from the simple "Name" and "Roaster", to the more fine-grained details like "Varietal" and "Harvest Date". To save you from typing it all out, on iOS 15 and later Brew Timer supports scanning coffee bags to automatically extract these coffee details for you. — Brew Journal — Every time you complete a brew, Brew Timer creates a new entry in your personal Brew Journal. Grind, coffee and water amounts are all tracked automatically. Record your own notes to capture thoughts on technique and taste for next time. — Brew Dashboard — After each brew, Brew Timer compiles a one-stop dashboard to make it easy to add tasting notes, reference coffee details, and tweak your recipe for next time. Brew Timer supports metric (mL/g) and imperial (fl. oz/oz) and will convert recipes to Aeropress-specific units for you. Brew Timer works without a scale, but it is recommended.

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.
