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

- WHAT IS LOÓNA? loóna is the first app that lets you quickly disconnect from a long stressful day and get in the right mood for sleep. - SO, IT'S ANOTHER SLEEP APP, RIGHT? Not exactly. loóna isn’t a list of direct go-to-sleep techniques, but rather a mood-altering app that helps you to stay calm during the day and prepares you emotionally for going to sleep in the evening. - WHY IS BEDTIME MOOD IMPORTANT? Negative emotions we accumulate during the day are processed and consolidated by our brain during sleep making them more difficult to disassociate from when faced again in the future. Moreover, feeling angry, anxious, down, or, the opposite, excited, and elated, is likely to affect latencies to sleep onset and REM-sleep. People mistake it for the symptoms of a sleep disorder, but in reality, they just may be in the wrong mood for sleep. - HOW DOES LOÓNA WORK? From the wake up and during the busy day Loóna will support your emotional states with playlists and immersive stories. Each night you’ll have a recommended escape. An escape is a guided session that combines activity-based relaxation, storytelling, and sounds in a unique way. Complete it to shut the frantic world out, reset your mind, and create the perfect mood for sleep. Loóna saves your escape sessions to your Apple Health app. The upgrade to loóna PLUS provides access to the entire collection of escapes. Our subscription options are: 1-month subscription,3-month subscription and 1-year subscription with a 7 day trial, (price may vary by location). Payment will be charged to iTunes Account at confirmation of purchase. Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period.

Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable.

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.
