Fintonic and Kesef both show you where your money goes, but they start from different places. Fintonic connects your bank accounts in Spain and builds your spending from what went through the bank; it also calculates a financial score and compares loans. Kesef doesn't connect to banks: it logs what you pay in cash, by transfer, by card or with Mercado Pago, in any country. The detail is below, with what Fintonic says on its site and help centre, and where it's better.
The short answer
If you live in Spain, your accounts are at banks on its list and you want to see your transactions without logging anything, Fintonic does that. It also gives you a free financial score and compares loans.
If you pay in cash, by transfer or with Mercado Pago, buy in instalments or share expenses, Kesef handles that. Fintonic's help centre says it only shows transactions that went through a bank account.

The real difference: what goes through the bank, or everything you spend
Fintonic builds your spending from what goes through your bank accounts. It's convenient, since there's nothing to log, but it leaves out whatever doesn't go through the bank: its help centre says cash transactions can't be added.
Kesef starts from the other end: it doesn't connect to banks, and it records what you log plus what comes in on its own from Mercado Pago or Apple Pay, with Kesef Pro. In Argentina, where a large share of payments come from Mercado Pago, cash or transfers, that's what makes the month complete.
And Fintonic has another business at its core: the financial score (FinScore) and loan comparison. Kesef doesn't offer loans or calculate a score: it's an app for tracking your expenses and shared ones.
Where Fintonic is better
- If your accounts are at banks on its list, your transactions arrive on their own from the bank, with nothing to log. Kesef doesn't connect to banks.
- It gives you a free financial score, updated every month, with tips to improve it.
- It compares loans from 40+ lenders, at no cost, according to its site.
- It's authorised by the Bank of Spain to access your accounts.
If you live in Spain, pay for almost everything with your bank card and don't share expenses, Fintonic shows you your spending without you doing anything.
