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

Pregnancy support that actually meets you where you are. Pregnancy comes with endless questions, 3am worries, and a healthcare system that wasn't built to give you the time or answers you deserve. Obi was created by board-certified ObGyn Dr. Noa Sterling to change that. As both an OB and a mom, Dr. Sterling experienced firsthand the gap between what women need during pregnancy and what they actually get. Every part of Obi is designed to fill that gap — so you feel informed, supported, and cared for at every stage. Because good pregnancy support shouldn't just sound reassuring. It should actually help. Inside the app, you'll get: Ask Obi — Your ObGyn-Powered AI Stop Googling. Ask Obi instead. Get trusted, evidence-based answers to your real pregnancy questions — any time of day or night — grounded in Dr. Sterling's clinical expertise.

Weekly, Personalized Pregnancy Content Access hundreds of expert articles, videos, and bite-sized education tailored to exactly where you are in your journey. From TTC through postpartum, the right information arrives exactly when you need it — no searching required. WellBeing Tools Built for the Pregnant Brain Neuroscience-backed mindfulness tools designed to stop worry spirals before they start. Simple, calming, and actually usable at 2am. Community You'll Actually Want to Be Part Of Connect with a private community of science-minded women who get it.

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.
