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

Get your s#!t together — calmly. Find a name you'll love, then get the whole pregnancy organized from one date. GYST Baby turns "what am I supposed to be doing?" into one gentle, personalized plan: from positive test to preschool, without the overwhelm and without the judgment. FIND A NAME YOU BOTH LOVE Swipe through 5,000+ names, each with a written background: where it comes from, what it means, how it's said, and how it reads in different cultures. Answer as many or as few questions as you like — style, heritage, how common is too common, letters, faith, anything that's off the table — then swipe one at a time or choose between four at once. It learns your taste as you go, so loving a few names teaches it the kind of name you like, not just those ones. Pair firsts with middles and send your shortlist to your partner. Behind it sits a 41,464-name corpus spanning 197 countries. TELL US ONE DATE. GET A WHOLE PLAN. Enter your due date (or your baby's birthday) and GYST builds your timeline: prenatal appointments, well-child visits, screenings and vaccine windows, and the to-dos that actually matter — each placed at the week it becomes relevant, never all at once. A CALM TODAY SCREEN One screen tells you where you are: baby's size this week, what's scheduled today, your next appointment, and the two or three things worth doing next. That's it. No streaks, no guilt. WEEK-BY-WEEK DEVELOPMENT See how baby is growing with friendly weekly facts drawn from trusted medical guidance, a size comparison you'll actually remember, and an encouraging note when you need it. AFTER BABY ARRIVES The plan grows with you. Track developmental milestones from the CDC's "Learn the Signs. Act Early." checklists (2 months to 5 years) — organized by domain, with tips for every age and clear guidance on when to check in with your pediatrician. Month-by-month "what's happening" cards keep you a step ahead. VISITS, PREPPED Every checkup comes with what to expect, how to prepare, and a checklist of questions worth asking — check them off in the waiting room, add your own. GYST SHOPPING A complete baby-gear checklist (100+ items) organized by category, with plain-English explanations of when and why you need each thing. Track who's buying what, estimated costs, stores, and links. No brands pushed, no sponsorships. BUYING GUIDES, NOT ADS 21 plain-English guides (strollers, car seats, monitors, carriers…) comparing the types — pros, cons, what to look for, safety notes — plus a 60-second quiz to find your fit. YOUR WHOLE TEAM Add your partner, grandparents, and caregivers. Assign purchases, then share your list, weekly updates, or milestone progress through Messages or email — you choose what leaves the app. EVERYWHERE YOU ARE iPhone, iPad (with a full sidebar experience), Apple Watch with complications, a Home Screen widget, and Live Activities on appointment days. Your plan syncs privately through your own iCloud. PRIVATE BY DESIGN No accounts. No ads. No tracking. Your information stays on your devices and in your own private iCloud — we never see it. The one exception is the baby shower wish list: publish one and the items you pick go to a page we host, so guests can open it without an app. Nothing else ever leaves. GYST Baby is an educational organizer, not medical advice. Content is based on commonly published U.S. guidance (ACOG, AAP, CDC) — always confirm with your own providers. They know you best.

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.
