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.

Give every unit of money a job. Pentos brings classic envelope budgeting to a modern ledger: assign what you have to category envelopes each month, spend against them, and watch what's left roll forward. You buy it once. It works entirely offline. Nothing about your money ever leaves your iPhone. WHY ENVELOPES Budgets fail when they're forecasts. Envelope budgeting only deals in money you already have: fund Groceries, fund Rent, and when an envelope runs dry, the shortfall is charged back against next month, so the numbers stay honest. Categories can carry their debt forward instead if you prefer. YOUR LEDGER, COMPLETE - Accounts with running and cleared balances, on- or off-budget - Fast entry with payee autocomplete, split transactions, and transfers that stay mirrored across both accounts - Statement reconciliation that locks rows once they match your bank - Search, rich filters, #tags, bulk edit, and a flag on anything still uncategorized RULES THAT DO THE TYPING Teach Pentos once: rules rename messy payees, set categories, and run on every import. Apply a new rule back through history in one tap. Payee merge tidies duplicates and never touches a reconciled row. SCHEDULES AND GOALS Scheduled transactions post themselves, or wait for your OK, and never drift: Jan 31, Feb 28, Mar 31. Give any envelope a target: a fixed amount, a save-by date, a share of income, and more. Then fund every goal in one tap. TWO WAYS TO BUDGET Strict envelopes, or a lighter tracking mode that simply shows what you saved or overspent each month. Switch any budget file between the two at any time without losing data. SEE WHERE IT GOES Net worth, cash flow, spending breakdowns, comparisons, and a calendar heat map, plus a dashboard you arrange yourself from saved report cards. A privacy switch redacts every amount when someone is looking over your shoulder. UNDO ANYTHING The undo arrow takes it back: edits, bulk changes, deletions. Hold it for a labeled history. Shake to undo works too. BRING YOUR BANK WITH YOU Import CSV, OFX/QFX, or QIF statements. Pentos learns each account's column layout, catches duplicates automatically, and re-importing the same file is always safe. PAY ONCE, KEEP IT FOREVER Pentos is not a service. There is no subscription, no account to create, and no server your budget depends on. Buy it once and it keeps working. LEAVE WHENEVER YOU LIKE One tap exports your entire budget as a portable backup file you can restore on any iPhone running Pentos, or as plain CSV for spreadsheets. It's your data, and you can take it with you anytime. PRIVATE BY DESIGN Pentos makes no network connections. No analytics, no telemetry, no cloud. Its privacy label reads "Data Not Collected" because there is nothing to collect.

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.
