Almost any app can add up what you have in the bank and with your broker. The hard part is everything else: the mortgage, which goes down a little every month (and moves with the Euribor if it's variable), the car, which is worth less every year, and the house. We looked at which apps work that out on their own and which leave it to you.

Net worth = what you own minus what you owe. Accounts and investments are the easy part: any decent app shows you their balance or market value. What separates one app from another are the three pieces that change value without any transaction hitting your account:
Your net worth comes from your accounts, your investment positions at market value (crypto too) and fixed-income products, plus the assets and liabilities you add yourself. That's where it pulls away from the rest:
All with history: you can see how your net worth has evolved month by month. The total and the breakdown are free; the history and the manual assets and liabilities (home, car, mortgage) are part of Cuéntamo Más. And on top of your net worth, Cuéntamo tells you how much money you'll have in each account over the coming months.
Free and in Spanish, on the web. It's the only one on the list that revalues your home automatically with Spanish data: it applies the INE house price index for your province from the purchase date. Cuéntamo doesn't do that. It calculates the mortgage with a theoretical French amortisation, but doesn't record real payments or changes to the loan, and doesn't handle variable rates.
It updates the mortgage balance every month according to its terms, at a constant instalment. If it's variable, you have to edit the rate yourself every time it changes. It charges in dollars (from $89/year) and the app is in English.
They all calculate your net worth and track your investments, but in none of them does the car depreciate on its own: you update it yourself. The mortgage is where they differ. Since version 2.2 (10 September 2026), Margen subtracts the instalments you pay from the outstanding balance automatically; its listing says nothing about variable rates, and it estimates your home's value on its Premium plan without explaining how. In September eXcenda added mortgage management with overpayments and rate changes, help deciding when to overpay, and a property's purchase costs (notary, taxes, land registry, agency fees, valuation, estate agent, mortgage, renovations), which count towards its acquisition value and return; it doesn't say it tracks the Euribor either. Dinerio says it plainly in its guide: the mortgage's outstanding principal "from your last statement". Finttery links the mortgage to the property and advertises debt automation on its paid plan without detailing it.
Kubera is a well-known international option, but it's English-only, costs $250/year and its automatic home valuation only works in the US. Portfolio Performance tracks an investment portfolio well and is free, but it has no liabilities: without the mortgage there's no real net worth.
We have a stake in this, so here are the reasons, against the table above:
If you're happy to enter everything by hand and just see the number, Dinerio, Neto or eXcenda also give you the total.
Cuéntamo is free to start: your net worth total and breakdown, plus the balance forecast. No bank connection, no ads, no card required.
