On-device personal finance

Where does your money actually go?

Most people can't say. FABZ is a very advanced calculator that keeps the answer for you — what you earn, what you spend, and when you'll actually hit your goals.

The FABZ statistics screen: monthly financial health and a donut chart of spending by category.

Try it — nothing installed

Watch it do the thinking.

This is the actual maths from the app, running in your browser. Build your own categories and watch the plan work itself out — nothing you type here leaves the page.

Your categories
The plan

Say you keep about $210 a month. In the app this is measured from your real months — here it's just a friendly assumption.

$0.00/month freed

Every number here was worked out in your browser. That's the whole app — no account, nothing sent.

And it quietly handles the rest

The unglamorous parts that make the numbers trustworthy.

Recurring costs, filed

Rent, insurance, subscriptions — set them once and they file themselves, so a fixed bill never gets mistaken for a spending habit.

Works entirely offline

No signal, no problem. There's no server to reach, so it opens and works the same on a plane as it does at home.

Counts in your currency

Pick your currency once and every total, chart, and goal speaks it — chosen from a full list, not assumed.

Privacy

Nothing leaves your phone.

There's no account to make and no bank login to hand over. Your records live in one file on your device, and there is no server for them to go to.

Every other app like this works by a company reading everything you've ever spent money on. This one can't, because it was never built to.
