Every currency on its own

Track income and spending. iPhone, iOS 16 and later.

Every expense stays in the currency it happened in. Totals are valued at the rate you actually got, the one you typed yourself. Works offline. No account, no analytics.

I get paid in one currency, spend in another, and change money at whatever rate I can get that week. Every finance app I tried quietly ruined that. Each one picked a "base currency", looked up today's market rate, and told me what my month had cost at a price I never paid.

Grossbuch does not do that.

Every amount stays in the currency it happened in

A 12 GEL coffee is 12 GEL, today and in five years. Account balances stay in the account's own currency. Nothing is silently rewritten behind your back.

The rate is the one you actually got

When you move money between your accounts you enter what left one and what arrived in the other. That is the rate — your bank's, your exchange office's, the one you argued for — and Grossbuch freezes it. It never goes looking for a market rate to overwrite it with.

Totals are what your money really cost you

Choose a report currency: the lens you read your month through. Every figure is valued at what you paid for that money, not at a rate somebody published. Open "How it adds up" and the app shows its working, currency by currency, so you can see which part of the total is a fact and which part is an estimate.

It works with no signal at all

There is no account to create, no sync, no sign-in, and no server of ours anywhere. The ledger is a file on your phone, and Grossbuch never sends it anywhere. The one thing it fetches, when it can, is the day's published rate table — nothing you enter goes with the request, and with no signal the app simply carries on without it.

What is in it

• Two taps to record a spend. Type the amount, tap a category, done — no confirmation screen. The category tiles reorder themselves towards what you actually use.
• Accounts in as many currencies as you like: cash, bank, card, savings.
• Transfers between your own accounts, with the real rate written on both sides.
• An opening balance for each account, so you can start keeping books today instead of re-typing three years of history first.
• Reconcile against your bank in one sheet when the numbers drift, without editing the past to make them agree.
• Statistics by month or by year, by category, with subcategories folded into their parent.
• History by day, with filters by account and category, and search by amount.
• Light and dark, and nothing but the system's own look.

A note on honesty

Sometimes there is no honest number. Your own rate is used first, always. Where you have no exchange history for what you spent, the app falls back to the nearest rate it knows — one you got yourself on another day, or a published one — and marks the row as the estimate it is instead of letting it pass for a price you paid; where it knows no rate at all, it says so on the row rather than inventing one. And it will never show you half a figure as though it were the whole one. That is the whole design, really: it would rather say "I don't know" than be confidently wrong about your money.

Nothing you enter is sent to us. No account, no analytics, no advertising.
