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

Friends is a social AI companion app with cute virtual pets you grow over time – alone or together with real-life friends. Raise AI companions, share moments, and build routines for focus, self-care, and connection. Friends turns everyday life into something more personal, social, and fun. Your AI companions learn from you, adapt to your routine, and evolve based on your interactions over time. Social AI Companions That Evolve With You Friends is social by design. Raise companions on your own or together with someone you care about — share progress, moments, and playful interactions along the way. Every action shapes their personality, unlocks new behaviors, and creates small surprises over time. Choose Your AI Companion Each companion supports a different part of your day: Pengu – A Shared AI Companion for Two People Pengu is a shared AI companion you raise together with a partner or close friend. Two people shape Pengu’s personality through conversations, choices, and shared interactions over time. Designed for couples, close friends, and siblings who want to build something together. Mellow – AI Study Buddy & Focus Companion Mellow is your calm AI study and focus companion. Mellow helps you stay on track with studying, homework, and daily tasks – adding gentle structure, reminders, and encouragement without pressure. Bao – AI Self-Care & Habit Companion Bao is your self-care AI companion for healthy habits and well-being. The more consistent you are, the more Bao develops – designed to make self-care feel motivating, rewarding, and easier to stick with. Raise Companions Together Raise companions with friends, send reactions and gifts, celebrate milestones, and enjoy a shared digital space that grows with your relationships. Often compared to a new generation of Tamagotchi-style experiences, Friends goes further by combining AI characters, real utility, and shared experiences with people you care about. Customize and Create - Personalize your companions and their world: - Outfits and accessories - Wallpapers and themed rooms - Visual upgrades that reflect personality and progress Friends Widgets Stay connected from your home screen.

Built on AI That Learns Over Time Friends is powered by AI designed to make companions feel more personal the longer you use them. Your companions learn from how you interact, adapt to your habits, and respond differently over time — remembering past moments and reacting to progress.

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.
