What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Built for the chair, not the back office. You don't need another app trying to run your salon. You need to remember what you put in Sarah's hair eight weeks ago. That's what Hair Notes is for. Open a client. Check the last formula. Snap a photo. Write a note. Move on. The whole app is built around the 30 seconds you actually have between clients. For every client, keep: • Color formulas and color history over time • Haircut reference photos • Before-and-afters • Contact info: add manually or pull from your Contacts • Preferences, allergies, the stuff you'd forget • Follow-up notes for next time Designed for how stylists actually work: • High-contrast interface readable in salon lighting • Searchable client records • Recent clients pinned to the top • Fast enough to open, use, and close between sections What Hair Notes is not: It's not a booking app. It's not a payment processor. It's not trying to charge you $40 a month to run a salon you already run just fine. It's a notebook. That's the point. Pay once. $3.99. Done. No account. No subscription. No salon software contract. Your data lives on your device. You own it. We don't see it, sync it, sell it, or hold it hostage. Built by an indie team. Made for stylists who'd rather spend their money on color than on software.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
