— 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 miscategorised 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 petrol 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.

VW GOLF GTI · APR €184
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.
