Budgets that match how you think
Choose zero-sum budgeting or the 50/30/20 rule, on daily, weekly, monthly, or quarterly periods. Every category is a need, a want, or an investment, so you always see the shape of your spending. It's the zero-based budgeting app for people who want their plan to fit their life, not the other way around.
Track spending without the busywork
Log transactions in seconds, split one purchase across categories, set recurring bills to post themselves, and scan receipts with AI to pre-fill everything. Returns and card payments are handled correctly, not counted as spending.
Savings goals with pockets
Create a goal, split it into pockets for your emergency fund, a vacation, or a new car, and allocate money over time. It's envelope-style savings you can watch fill up, pocket by pocket.
Reports that answer "where did it go?"
Spending trends over time, needs, wants, and investment breakdowns, and period-over-period comparisons in soft gold-toned charts. No formulas, no chart-building, no broken cells.
Budget together
Invite your partner or family to one shared account. Everyone logs spending, everyone sees the same numbers, admins control the settings. Ronin is a budget app for couples and families who want one source of truth.
Your bank doesn't budget for you. Neither do we.
Ronin doesn't pull transactions from your bank. You enter them, and that's the point. Recording a purchase takes seconds, but it means you actually see it, catch what's wrong, and never wake up to a month of silently miscategorized spending. If you've ever kept a budget in a spreadsheet, you already know: the awareness is what changes behavior. Ronin keeps that, and drops the formulas.
You see every purchase
Nothing slips in unnoticed. Every transaction crosses your eyes at the moment you record it.
You stay in control
Your categories, your rules. No auto-guessing quietly filing things in the wrong place.
Less typing than you think
AI receipt scanning, recurring templates, and CSV import do the heavy lifting.
Ronin has no bank syncing and no current plans to add it. Manual is the point.
Works like an app, because it is one
Ronin is an installable web app. Add it to your home screen on iPhone or Android and you get a native-feel experience with a bottom tab bar. Turn on push alerts when a category crosses its threshold or a budget period is ending, included with Premium.
