Generating… usually about a minute.
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.

HomeTally is a quiet, private home budget for the whole family — built so your financial information stays private and under your control. No accounts. No tracking. No subscriptions. Pay $4.99 once and the app is yours, working entirely on your iPhone, iPad, and Mac. WHY HOMETALLY Most budget apps want your bank logins, your email, your data — and they charge you monthly for the privilege. HomeTally takes the opposite approach. Everything you enter stays on your device — or, if you choose, in your own private iCloud — protected by your device's encryption and an optional Face ID, Touch ID, or passcode lock. There are no servers we operate, because there don't need to be. It's your money. It should be your business. WHAT IT DOES - Accounts — Track checking, savings, credit cards, cash, loans, and investments. Each account works like a digital checkbook with a running balance. - Transactions — Record expenses, income, and transfers between accounts. Search, edit, and clear them as they post at your bank. - Categories — Comes with a thoughtful set of categories, or create your own with custom colors and icons. - Tags — Add your own labels for the things categories don't capture: a trip, a home project, a tax deduction. A transaction can carry as many as you like, and any tag can be filtered or turned into its own PDF report. - Budgets — Set monthly limits per category and watch the progress bars track your spending in real time. Green when you're comfortable, amber as you approach the limit, red when you've gone over. - Import — Bring transactions in from your bank as CSV or OFX files. HomeTally detects duplicates and suggests categories based on your history. - Recurring — Set up rent, paychecks, and subscriptions once. HomeTally creates them on schedule — and catches up automatically if you haven't opened the app in a while. - iCloud Sync (optional) — Keep your iPhone, iPad, and Mac in step through your own private iCloud. You choose when to turn it on, nothing is merged or replaced without your say-so, and you can switch back to On Device anytime. A status indicator shows exactly where your data stands. - Reports — Generate clean PDF reports for any month or year. Perfect for tax time, financial reviews, or just keeping records. - Backup & Restore — Save a complete copy of everything to a file you control, and restore it whenever you need to. Your safety net when you switch devices, or when you simply want a copy that isn't in anyone else's hands. - Dashboard — See your net worth, monthly totals, spending by category, and budget progress at a glance — and browse back through any earlier month. FOR YOUR iPHONE, iPAD, AND MAC HomeTally is a native universal app for iPhone and iPad that also runs on Mac with Apple silicon. PRIVACY YOU CAN TRUST - No data collection of any kind - No analytics, no tracking, no advertising - No user accounts or sign-ups - Works fully offline - Encrypted on device with iOS Data Protection - Optional Face ID, Touch ID, or passcode lock - Export your data anytime as PDF reports, or save a full backup file Your data lives on your device. If you choose to turn on iCloud Sync, it goes only to your personal, private iCloud — which we cannot see or access. Either way: no accounts, no servers of ours, no analytics, no tracking. ONE-TIME PURCHASE Pay $4.99 once. No subscription, no in-app purchases, no upsells. You buy the app, and the app is yours.

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.
