Track spending. Split debts. Stay on budget.

Log an expense in two taps
Type an amount, pick a category, and save. Quick-amount buttons and a ± day shifter cover the rest of what usually slows this down.

What it does
Fast entry
Quick-amount buttons and category chips — most expenses are one tap plus a number.
Monthly budgets
Budget-vs-actual by category, so you know where the month stands before it ends.
Recurring & long-term
Bills that repeat and savings goals that build up over time, tracked automatically.
Split with friends
A real Czech QR payment code per debt, and a link that works for anyone, no account needed.
Works like an app
Add it to your home screen and use it like a native app — no app store, no install.
Yours, privately
Signed in with Google, your data is tied to your account alone — nothing shared, nothing sold.
About
Kasička (Czech for "piggy bank") started as a way to track my own spending and the money friends and I owe each other. It's built and maintained by one person — me, Pavel — in my spare time.

Privacy & terms
Kasička is provided as-is, free of charge, with no warranty of any kind. I can’t guarantee it will always be available, error-free, or fit for any particular purpose, and I’m not liable for any loss, damage, or missed payment arising from its use — including anything to do with the amounts, budgets, or debts you track here. This isn’t legal advice; if you need something more formal, talk to a professional.
Your data is stored in a private Supabase project and tied to your own Google-signed-in account — I don’t sell it, share it, or look at it beyond what’s needed to keep the app running and fix bugs. A public debt-share link reveals only what you choose to share (an amount, a note, a payment QR code) — never your account.
This runs on free hosting and database tiers. If that ever needs to change, I’ll say so clearly here rather than let it be a surprise.
This is a personal project, not a company — there’s no support team, and features come and go as I have time for them. Please don’t treat it as your only financial record.
