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

Stop guessing. Start understanding. Download Flowjo and become the partner she brags about. Flowjo is the first cycle-tracking app built for boyfriends, husbands, and partners. Instead of leaving you guessing why she's upset or what she needs, Flowjo gives you a clear, phase-by-phase playbook so you can show up as the best version of yourself — every single day of her cycle. HOW IT WORKS Enter her name, her last period start date, and her cycle length. That's it. Flowjo does the rest — automatically calculating which phase she's in and giving you real, actionable guidance. KNOW WHAT PHASE SHE'S IN Her cycle has four distinct phases — Menstrual, Follicular, Ovulation, and Luteal (PMS territory). Each one affects her mood, energy, and needs differently. Flowjo shows you exactly where she is, with a beautiful visual tracker and countdown to her next period. THE PLAYBOOK — YOUR CHEAT CODE For each phase, get specific tips on: • What to DO — thoughtful actions that make her feel supported • What to AVOID — common mistakes that make things worse • What to SAY — the right words for the right moment • GIFT IDEAS — small gestures that go a long way Plus, learn what she's actually feeling in each phase — so you understand the "why" behind her mood. FULL CYCLE CALENDAR See the entire month color-coded by phase. Know what's coming before it arrives. Add her next period to your calendar so you're always prepared. PMS EXPLAINED Not sure what PMS actually is? Flowjo breaks it down — the biology, the symptoms, and most importantly, how you can help. No medical jargon, just real talk. BUILT WITH RESPECT Flowjo is designed to be used with your partner's knowledge. It's not about surveillance — it's about empathy. Every user agrees to use the app respectfully before getting started. NIDDAH MODE for those who observe. WHY SPOUSES LOVE FLOWJO • No more "what did I do wrong?" moments • Know when to bring comfort vs. when to give space • Feel confident instead of confused • She'll notice the difference — trust us

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.
