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

Enjoy the aesthetic beauty of koi and the playful charm of a realistic lotus pond. The koi pond is filled with beautiful, carefree fish—plump, adorable, and full of life. It’s the perfect place to pause, soothe your weary mind and body, and lift your spirits. You can watch and play with the beautiful fish—feed them, tease them, ripple the water to stir them up, and interact with them in various ways. Admire a variety of flowers and foliage. Use the diverse range of decorative elements—not just for show, but for interactive fun: click and drag to place shapes, and choose between flowing or static special effects. Play with the water; experience incredibly realistic splashes and perfect 3D effects that showcase the true nature of water. Switch between various built-in sound effects (including domestic pets, wildlife, birds, whales, insects, frogs, nature sounds, ambient mixes, flowing water, weather sounds, artificial noises, and more—with a rich and growing library). You can also play your own favorite music. Change the background or use your own photos and images to customize the pond's setting. Mix and match elements—flowers, leaves, feathers, and more—with built-in or custom backgrounds and sounds to create your own unique lotus pond scene. Combine koi with nature sounds and music. Play nature sounds or music individually, or mix them together for a harmonious blend. Enjoy the dual pleasure of listening to music while watching and playing with the beautiful fish. It brings joy and relaxation during your downtime, aiding in rest, sleep, exercise, quiet reflection, meditation, or even a quick, soothing break at work. It is also perfect for children; they can play in this beautiful pond while learning about various adorable animals—let these cute creatures grow alongside your little ones! The animal family keeps growing, as they love your little ones too. Stunningly beautiful, realistic, and fun for all ages—easy to pick up and play instantly, with no complex setup required.

You can even take screenshots and record videos to show off your luxurious koi pond on social media, displaying just how well you’ve raised these beautiful, chubby, and adorable fish!

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.
