Oursum
Import any bank export, let the app learn your categories, review the report, and settle costs with your partner — all without leaving your Mac.
Built for households that want a clear picture of their finances without any cloud service or subscription.
Drag and drop any CSV or Excel bank export. The app auto-detects encoding and guides you through a column-mapping wizard — then saves the profile so next month's import is one click.
Reassign a category once, and Oursum asks if you'd like to remember that rule forever. Future imports are categorized automatically — the app gets smarter with every correction.
A daily-use home screen with summary stats, a category pie chart, and a sortable transaction table. Filter by time period, category, and amount range simultaneously.
Settle up with your partner or flatmates. Define contributors with equal, percentage, or fixed splits. Pre-populated from your active report filter — no re-typing needed.
Import the same file twice by mistake? No problem. A content fingerprint ensures each transaction is stored exactly once — no duplicates, ever.
English, Italian, German, French, and Spanish. Switch language, number format, date format, and currency symbol from the preferences panel — changes apply instantly.
Mountain dark — alpine stone and forest greens — and Seaside light — Mediterranean coast and clear sky. Both designed for long sessions without eye strain.
Add individual transactions by hand — cash, refunds, manual income — without ever needing a bank export. Full category assignment included.
Every import is logged: date, filename, profile used, rows imported, overwritten, and failed. Full transparency into how your data got here.
Every month, from raw bank export to settled household costs — in under 15 minutes.
Drag your bank's CSV or Excel export onto the app. Map columns once, save a profile, skip the wizard forever.
Rules run automatically. Fix the few uncategorized rows — each correction trains the next import.
Explore your spending with the pie chart and filters. Sort, click categories, and spot outliers instantly.
Open the split calculator, confirm contributors and proportions, get the settlement figures. Done.
