Oat Budget is a shared budgeting app made for couples. Connect with your partner and keep one budget together — who spent what, how much is left, and what you're saving toward, all on a single screen that updates in real time.
And you don't have to plan alone. Oat Budget's AI sets up your month and looks back on it with you.
PLAN THE MONTH WITH AI
Tell it your income and fixed costs, and AI drafts realistic category limits and a savings goal for the month. Start from a template that fits you — tighten spending, save first, build an emergency fund, split into buckets, or set a daily allowance — then adjust anything you like.
A MONTHLY REVIEW, WRITTEN FOR YOU
When the month ends, AI reads your spending and tells the story: where the money went, what changed from last month, and what you did well. Pick from four tones so it sounds the way you like to hear it.
SEE YOUR MONEY CLEARLY
• Income, expenses, and remaining budget at a glance
• How much you two can spend today
• Category limits with live progress bars
• Donut breakdowns and month-over-month comparisons
• A calendar view of every day's spending
BUILT FOR TWO
• Invite your partner with a code — one budget you both share
• When one of you logs an expense, the other sees it instantly
• See who spent what, side by side
LESS TYPING
• Snap a receipt and let it fill in the amount
• Recurring income and expenses post on their own
• Quick category and memo suggestions as you go
Start on your own if you like, then invite your partner when you're ready. Free to use, in your local currency.
Designed for iPhone (iOS 26 and later).

Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
• Fixed a freeze: the dashboard could stall for a moment once you had a lot of entries this month. It opens right away now, no matter how much you've recorded.
• Lists and statistics feel lighter too.
• Fixed a rare crash when opening category management.
• Also fixed being signed out when opening the app offline. If your records look empty, sign out and back in — everything is safe on the server.
