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

The Oh Baby! Fitness Pregnancy Weekly Workout shares everything we've learned from training nearly 30,000 women in prenatal and postnatal fitness. Each week's video will help you strengthen and tone muscles needed for a healthy pregnancy and delivery. Each exercise is designed to provide you with the most appropriate workout for your week of pregnancy using Pilates, Yoga and strength training exercises you can do at home with no additional equipment. Short videos and descriptions will show you exactly how to do the exercise and will explain how the exercise will help you build muscle or relieve stress. String exercises together to make your own personalized, SAFE pregnancy workout. You can also track your workout each day, and note how you liked the exercise and if it was challenging, etc. Features: * Due Date Calculator - Enter your due date and immediately see an exercise that's best suited for your CURRENT week of pregnancy. You'll be able to view exercises for PAST weeks of pregnancy and FUTURE weeks of pregnancy too. * Weekly Exercise Videos - Specific exercises with short videos for each week of pregnancy up to 40 weeks. Each exercise has three notations: 1) What it does (the muscle group the exercise focuses on) 2) What to watch for (specific modifications for exercise) 3) Number of times (reps) you should do of the exercise * Tracker: A special "tracker" feature shows you how many times you've done an exercise, on what date, and any notes you make about it. * Favorites: You can mark and keep track of your favorite exercises. * Resources: We supply links to valuable resources, blogs, videos and more. The American Congress of Obstetrics and Gynecology recommends pregnant women work out for 30 minutes on most if not ALL days of the week. Walk, swim or combine your favorite exercises from this app for your very own safe workout program tailored just for you.

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.
