Caffeinated Checkbook | Know Where Your Money Goes

Works Everywhere

Phones, tablets, and a real native desktop app — not a mobile UI in a wrapper. Same data, same speed, every device.

Offline-First, Private by Default

Your data lives on your device. No bank connections, no account required to start, nothing shared without your say-so.

No Ads, No AI

Every feature works on every device, free. Add multi-device sync as a subscription when you’re ready.

Why I built this

I used GnuCash for years. Life got complicated, I fell behind, and nothing I tried synced cleanly between my phone and desktop. So I built something that does. Read the full story

Smart entry, your categories

Selecting a payee auto-fills amount, category, memo, and reference number from your last entry with that payee. Recurring bills post on schedule. Custom categories fit how you actually spend — not a fixed set someone else picked for you.

Always know where you stand

Your running balance updates on every entry. Cleared and uncleared totals are tracked separately so you always know what’s actually available. Reconcile against your bank statement when you’re ready, with a side-by-side workflow on tablet and desktop.

Reports that make sense

Spending by category, payee, or tax status. Cash flow month over month. Year-over-year comparisons. Tax-relevant categories grouped for Schedule A at year end. Export anything to CSV.

Built for the way you actually spend

Not a bank app. Not a budget envelope system. A clean register that captures every transaction so you can see exactly what’s happening with your money — as fast as a paper checkbook, with reconciliation and reports built in.
