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

LonelyChat is a messenger with one rule: you can only talk to one person at a time. One friend. One conversation. No group chats, no feed, no inbox full of people waiting on you — just the person you chose, and your full attention on them. WHY ONLY ONE? Most messaging apps keep you juggling dozens of chats and half-listening to all of them. LonelyChat does the opposite. With room for exactly one friend, every message matters and nobody gets a distracted reply. CHOOSING SOMEONE NEW • Long-press anyone on the globe and send a friend request. They decide: accept or decline. • Already have a friend? Then saying yes to someone new means letting your current friend go. It's a real choice — on purpose. • Past conversations stay as read-only history, and you can delete them anytime. • Rather not be asked? Turn off "Allow friend requests" in Settings. • Know them already? Add them directly with their 8-digit code. EVERYTHING A GOOD CHAT NEEDS Photos, videos, stickers and GIFs. React to messages, reply to a specific line, search your history, see when your friend is typing and when they've read you. Kept intentionally simple. TO THE WORLD Step onto a shared pixel globe and hold up a sign for everyone to see. Broadcast a line to the whole solar system, heart someone else's, and notice strangers passing by — a small public square beside your one private chat. TO THE SOLAR Travel to other worlds. When you and your friend are on different planets, messages travel at the speed of light — a note to Mars really does take minutes to arrive. A playful reminder that distance is real. PRIVATE BY DESIGN • No ads, no trackers, no third-party analytics. • Block and report anyone, anywhere in the app. • Delete your account and data whenever you want. LonelyChat isn't trying to maximize your screen time. It's a quieter place for the one conversation that matters.

Opportunities

AI-GENERATED OPPORTUNITY HYPOTHESES

These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.

Hypothesis 1

Implement group chats and threaded conversations.

Assumption to check: Lack of user engagement features like groups or threads

Validate with people who use this workflow before building.

Hypothesis 2

Allow users to customize profiles with themes and layouts.

Assumption to check: Limited profile customization

Validate with people who use this workflow before building.

Hypothesis 3

Enable users to share images and videos in chats.

Assumption to check: Absence of media sharing features

Validate with people who use this workflow before building.

Hypothesis 4

Incorporate moderation features to ensure safe interactions.

Assumption to check: No content moderation tools

Validate with people who use this workflow before building.

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.
