Yes, you can build a budget app that gives every dollar a job, starting with manual entries.
You can build budget categories, assign your available money, and track spending against each category. Start with manual entries and saving on your phone, then add bank connections through Plaid if you want them.
The checker split your own version of YNAB into its key parts and sorted each one.

Needs setup
An iPhone app makes it easy to check your budget and log spending on the go.
Plan ahead: Budget totals need to stay trustworthy, so test refunds, overspending, and month changes before relying on the app.
Written by the checker for a first version. Paste it into Vibecode as is, or change it to make the app yours.
Build an iPhone app for people who want to give every dollar a job. The main screen should show this month's money left to assign and a list of budget categories with assigned amounts, spending, and available balances. Tapping a category lets me change its assigned amount. An Add Transaction button opens a simple form for income or spending with an amount, date, category, and optional note. Income increases money left to assign, and spending reduces the selected category's available balance. Save my changes on the device. Use a clean cream and green design with clear numbers and red warnings for overspending. Start with realistic sample income, categories, and transactions that add up correctly.

Vibecode builds a first version from one prompt, and the checker would start with these parts: monthly category budget with assigned money, available balances, and a left-to-assign total; manual income and expense entries that update the budget; on-device saving so your budget stays between visits. Plan on an afternoon for a working first version with its real features.
Vibecode's first build is free for new accounts that sign up with Google or Apple on the web or the iPhone app, as the account's first project: one build of about 10 minutes with up to 3 features, on sample data. After that you need credits, from a paid plan or auto-reload. For your own version of YNAB, the checker lists these costs: Vibecode Plus ($20 a month); Apple Developer Program ($99 a year); API key for Plaid (that service's pricing).
YNAB pairs budgeting with an established community, budgeting education and a support team that helps people use its method. A version you build yourself won't have these: YNAB's established budgeting community; YNAB's budgeting education library; YNAB's dedicated support team.
YNAB's monthly plan costs $14.99 a month. That's from YNAB's own site, checked on October 21, 2026.
