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

The tea timer that respects how tea is actually brewed. Whether you're pouring a quick cup of black tea or running a five-infusion gongfu session, Tea Timer gives you the exact temperature, ratio, and steep time for the tea in your cup. Not a generic 3-to-5-minute guess. Four brewing styles in one app • Standard. Single steep, the way most of the world drinks tea. • Gongfu. Sequential short infusions, each pour timed individually. • Japanese. Shorter, hotter, traditional Japanese style. • Cold Brew. Long, gentle extraction in the fridge. Eleven teas, dialed in Green, white, oolong, black, pu-erh, herbal, sencha, gyokuro, genmaicha, hojicha, and matcha. Each preset has a research-backed default temperature (°C or °F), a tea-to-water ratio in grams, and a per-infusion time. Built for the brew, not the cup • Multi-infusion timer that walks you through every steep. • Adjust temperature, ratio, and time per tea, saved automatically. • Visual session progress so you never lose your place mid-flight. • Local notifications when your tea is ready. • Haptic feedback at start, finish, and each infusion change. • Works offline. No account required. Designed to disappear into the ritual Calm color palette. Big, legible numbers. No ads. No social feed. No login. Open the app, pick the tea, hit start. That's it. For people who care about tea If you've ever ruined a cup because you forgot the timer, lost track of which infusion you were on, or wished your kitchen timer knew the difference between sencha and gyokuro, this app is for you. Tea Timer also runs free on the web at teatimer.app. Same presets, same brew, on whichever device is closest to your kettle. Brew better. Every cup.

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.
