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.

Your bank shows you a balance. Monbark shows you how long it will last. Monbark requires a subscription and a supported US bank account. Check that your bank is supported, connect it, and see your own runway before you decide to subscribe. If the connection fails or you cancel, no purchase is offered. Your runway is the number of days until your money runs out at your current pace. One number, refreshed daily from your bank and built from your real transactions. It's an estimate, not a guarantee. No spreadsheets. No typing in every coffee. ONE NUMBER THAT MEANS SOMETHING Most people check their balance and still don't know if they're okay. Monbark answers the real question: how many days do I have? KNOW WHAT'S SAFE TO SPEND See what you can spend today without touching next week. Your known bills and savings plans are counted first, so the number you see is closer to what's really yours. A VERDICT FOR YOUR DAY Open Monbark to a one-line read on your day: what landed, what's due, and whether your cash covers it. YOUR KNOWN BILLS IN ONE PLACE Rent, phone, electric, subscriptions. Monbark looks for recurring charges in your bank history and lines them up by due date. Review what it found, add any it missed, and mark bills paid. Add a bill by typing it or saying it: "Water $38 on the 15th." LIMITS FOR THE MONEY THAT MOVES Groceries, gas, dining, life. Set a limit, watch the pace, and see when you're running hot before the month is over. Every category sits next to last month's number, so you can see where it goes. GOALS PRICED IN DAYS Saving for a trip? Plan how much to set aside each payday and see if you're on pace. You move the money yourself; Monbark never transfers funds. Log savings records your progress, shows what each contribution costs you in runway, and when you'll get there. EVERY PURCHASE COSTS TIME Monbark turns each expense into what matters: how many days it takes from your runway. ASK YOUR MONEY ANYTHING "Will I make it to payday?" "Can I afford this trip?" Advisor answers using your own numbers. Advisor and voice bill entry use AI (Claude by Anthropic), and Monbark asks your permission before sharing any data with it. MORE THAN ONE BANK? MONBARK PLUS Checking, savings, and credit cards across up to 3 banks, combined into one number for how long your money will last. One connection is one bank login, which can include several accounts at that bank. PRIVATE BY DESIGN Monbark connects through Plaid and can only read your accounts. It can't move money, and it never sees your bank password. If you connect a bank and don't subscribe, we disconnect it and delete its data within 48 hours. Delete your account and your data any time from Settings. Available in the United States only. Works with US banks. Your money, measured in days. ——— SUBSCRIPTION TERMS Monbark Pro (1 bank connection): $9.99 per month or $59.99 per year.

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.
