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

Koree Moon is your cycle wellbeing companion — built to help you understand your body, not just track your period. Log how you feel, what you experience, and what matters to you. Cycle symptoms, mood, energy, pain, thoughts, and events all in one place. Your history builds into patterns. Your patterns build into understanding. MOON PHASE CONTEXT Moon phase is calculated on your device using a precise mathematical model — no internet connection required. See how the lunar cycle aligns with yours, every single day, even offline. FULL iOS CALENDAR INTEGRATION Your iOS calendar works with you, not separately. Create events, set reminders, and manage recurring plans — all synced natively to the calendar you already use. CYCLE TRACKING THAT LEARNS As you log more cycles, Koree Moon builds a more representative picture of your unique pattern. Cycle phases, period predictions, and day-level context all improve as your history grows. REFLECTIVE THOUGHT LOGGING Capture thoughts, emotions, and personal notes alongside your physical symptoms. Understanding how you feel mentally and physically together reveals patterns that neither can show alone. ACCOUNT-LINKED LESSONS Access structured wellbeing content tied directly to your account and progress. PRIVACY FIRST Your health data is stored securely and never sold or shared with advertisers. You control your data and can delete it at any time. Koree Moon is designed for real life — across iPhone and iPad, across your whole cycle. Start understanding yourself.

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.
