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

An alarm tells you when you're already late. Kumo does the opposite: it shows the time you still have, counting down to your next event before it arrives. Pick events from your existing calendar. Kumo shows a live countdown at the top of your screen and on your lock screen. No math in your head, no surprises once your event arrives. Just a clear amount of focus time sitting in plain sight, so you can settle into what you're doing now with room to breathe. Made for people with time blindness, ADHD, or anyone whose sense of time doesn't run on a clock. How it works: Connect the calendar already on your iPhone Tap one event or several to start their countdowns Watch the time count down on your lock screen and the top of your phone (Dynamic Island) Pick as many events as you like, and Kumo keeps up as your calendar changes: add, move, or cancel something, and your countdowns follow. Works with iCloud, Google, Outlook, and any other calendar in the iOS Calendar app. Your calendar stays yours. Kumo reads your events on your device to show your countdowns. No subscriptions. No accounts.

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.
