A Lunch Money alternative for multi-currency people who own cars

Lunch Money is built for people who actually think about their money: multi-currency as a first-class idea rather than an afterthought, crypto alongside cash, CSV and PDF import that works, a real developer API, and one all-inclusive price instead of a feature ladder. It's clean, it's fast, and it doesn't treat you as someone who needs to be nudged.

Its audience — cross-border workers, digital nomads, engineers, founders — is the same crowd that gets badly served by mainstream budgeting apps. If that's you, it earned its reputation.

Parts of this comparison are a genuine tie, and saying so is more useful than manufacturing differences. On foreign currency especially, both apps do what almost nobody else bothers to:

• The rate comes from the transaction's own date, not today's — a receipt from three weeks ago is valued at three weeks ago's rate.
• The rate is stored per transaction, so a figure you read last year still reads the same this year.
• Rates refresh daily, so recent entries convert against something current rather than a stale snapshot.
• Everything rolls up into one primary currency, so spending scattered across countries adds up to a single number you can budget against.

Most budgeting apps do none of that. They keep the foreign amount and convert the lot at whatever today's rate happens to be — invisible until the year you spend a lot abroad, and permanently wrong after it. So if you're weighing up these two, that's a box you can stop checking on both; and if you're considering some third app, it's the first question to put to it.

One caveat on our side, since this section is about being straight with you: FlexiBudget applies the date-correct rate when your data syncs, which is the paid plan. The free plan converts at today's rate.

It's a browser tab. Lunch Money is web-based, with a responsive interface rather than an installable app. On a laptop that's fine — arguably better. Standing at a gas station with one bar of signal, it isn't, and that's exactly the moment a fuel log has to be usable or the habit dies.

There's no vehicle in it. Fuel is a transaction with an amount, which is true and insufficient. No odometer, so no consumption. No liters or kWh, so no price-per-unit trend. No service intervals, no cost per kilometer, no total cost of ownership — so the car that's probably your second-largest running expense is a category with a number in it.

And bank sync only reaches so far. Automatic import runs through Plaid, which covers the US and Canada. Outside that you're on CSV imports and manual entry regardless — so for a European user, the automation advantage over a manual-first app is smaller than it looks.

It installs, and it works with no connection. FlexiBudget is an offline-first progressive web app: add it to your home screen or dock and it opens in its own window on iPhone, Android, iPad, Windows, macOS or Linux. The data lives in a database on the device and is read from there first, so the app is fully usable on a plane, in the metro, or at that one-bar gas station. Sync between your own devices is optional and paid.

There's a free plan. The whole app on one device, forever, no card — which matters if you're not sure a budgeting habit will stick. Cloud backup, cross-device sync and historically accurate exchange rates are the paid tier.

And the car becomes a ledger. Refuels with odometer readings and tank-to-tank consumption in L/100km, L/km or MPG; gasoline, diesel, LPG, CNG, electricity, AdBlue and hydrogen, with a plug-in hybrid's fuel and kWh averaged separately; services with parts and labor split out and interval reminders; cost per kilometer. Every entry lands in your budget at the same time — one entry, both effects.

If you're in the US or Canada and real bank sync is what keeps you consistent, stay — FlexiBudget has no aggregation at all and won't pretend that's a free win.

Likewise if you lean on the API, the crypto tracking, or the import tooling. Those are deliberate power-user features, they're well built, and nothing here replaces them. And if breadth of currency coverage is what you need, Lunch Money's 160+ is wider than ours.

The case for moving is narrow and specific: you want the app on your phone rather than in a tab, you want it to work when the signal doesn't, and you want the vehicles that eat your money to be modeled as vehicles.
