— Customizable dashboard

Every other app decides
what you should see.

FlexiBudget doesn't. You get an empty grid, a catalog of widgets and tabs you name yourself — so the home screen shows what you open the app for, not what we guessed the average user wants. Layouts save per device, so your phone and laptop don't have to agree.

— Three reasons this app exists

Made for three kinds
of people.

FlexiBudget wasn't built to replace every budgeting app — it was built because three specific things were consistently missing from the ones we tried. If any of these sound like you, welcome home.

01 · CONTROL, NOT AUTOMATION

For the people who want to run their budget, not watch it.

Every transaction is typed — deliberately. In return you get no broken bank feeds, no credentials handed to an aggregator, no miscategorized charges to untangle on Sundays. Pin your recurring expenses as quick buttons and most of your logging becomes two clicks, literally: tap, save.

Made for you if
You've been burned by broken sync, or you simply want the act of logging to keep you aware of your spending.
02 · A REAL VEHICLE LEDGER

For the people whose car is a second household.

Most budgeting apps give you a "Car" category and call it done. FlexiBudget gives you refuels with mileage, cost-per-km, multi-fuel tracking (a plug-in hybrid's gasoline and kWh, tracked separately), parts and labor split on every service, and service-interval reminders so the timing belt doesn't surprise you. Built because I was tired of tracking all this in a spreadsheet.

CONSUMPTION l/100km ↓0.3 7.4 l
FUEL €/KM ↓€0.02 €0.11
NEXT SERVICE 1,240 km
Made for you if
You drive, cycle, or ride something that costs money — and you want the fuel log, service history, and total cost-of-ownership in the same place as your groceries.
03 · HISTORICALLY CORRECT FX

For the people who live in more than one currency.

Entering a forgotten transaction from three weeks ago? FlexiBudget converts it using the exchange rate from that day — not today's. Charts and stats re-compute each entry against its period-accurate rate, so volatile currencies don't quietly distort your totals. Most apps get this wrong.

Never any ads

Not now, not ever. Your budgeting app should manage money, not sell attention.

We never sell your data

Your financial data is personal. It stays on your device — sync only to your own devices.

True offline-first

Works on a plane, in the metro, in an underground parking lot. Log that expense the moment it happens, no signal required.

Budget + vehicles

The only app combining personal budgeting with full vehicle management. Zero double entry.

Your data, your device

On the Free plan there's no backup — your data lives on your device, nowhere else. Clear your browser or lose your phone and it's gone. Standard adds cloud backup so you can restore on any device.

Built by a small team

FlexiBudget is built by a small team. Your subscription directly funds development — no investors, no ads, no data sales. Every paying user makes the next feature possible.

— Common questions

The ones people
ask first.

Read the full FAQ →

Is there a single app that does both personal budgeting and vehicle expense tracking?

Yes — that is what FlexiBudget was built for. It combines a full household budget (categories, budgets, accounts, payees, projects) with a proper vehicle ledger (refuels with odometer readings, fuel economy, servicing, parts and labor). Fuel-log apps such as Fuelly, Drivvo and Fuelio track the car but have no household budget; budgeting apps such as YNAB, Bluecoins, Spendee or PocketGuard give you a flat "Car" category with no odometer, consumption or service history.

How do I track car expenses without entering everything twice in two apps?

Log the refuel or the service once, in the vehicle. FlexiBudget records the vehicle detail (odometer reading, liters or kWh, price per unit, parts and labor) and the money side of the same event at once, so the spend lands in your monthly budget and your category totals automatically. There is no export, no reconciliation and no second entry.

Is there a Fuelly, Drivvo or Fuelio alternative that also tracks the rest of my spending?

FlexiBudget covers the same ground a dedicated fuel log does — refuels with mileage, fuel consumption trends, cost per kilometer, service intervals and reminders — and then puts those costs in the same ledger as your groceries, rent and subscriptions. See the alternatives comparison for how the two families of app differ.

Can I choose what appears on the dashboard, or is the layout fixed?

You build it. The dashboard is a grid you fill from a widget catalog — quick-add buttons, charts, recent transactions and vehicle events, refuel and service shortcuts, section headers — and you group those widgets into tabs you name yourself, such as Today, Bills, Fleet or one per vehicle. Nothing is a fixed home screen chosen by the developers. The layout is also saved separately per device, so your phone and your laptop can show completely different things.

Does it work on my phone, tablet and laptop?

FlexiBudget is a progressive web app, so it runs in any modern browser — iPhone, Android, iPad, Windows, macOS and Linux — with no app-store install required. You can add it to your home screen or dock so it opens like a native app. Each device keeps its own dashboard layout, so your phone can show quick-entry buttons while your laptop shows charts.

Do I have to connect my bank account?

No. FlexiBudget has no bank aggregation at all, on purpose. Every transaction is entered by hand, which means no banking credentials handed to a third party, no feeds silently breaking, and no miscategorized charges to untangle later. Recurring expenses can be pinned as quick buttons so most logging takes two taps.

What does the free plan include?

The free plan is the complete app on one device, forever: unlimited accounts, categories, budgets and vehicles, the full vehicle ledger, a personalized dashboard, today's exchange rates and no ads. What it does not include is cloud backup, cross-device sync and historically accurate exchange rates — those are the paid Standard plan at €3.50 per month or €25 per year. On the free plan your data lives only on that one device, so losing the device means losing the data.
