Best App To Connect Activobank Revolut And Ing Spain

The Best App to Connect ActivoBank, Revolut, and ING Spain — And Why One View Beats Three

The answer is not one of the three bank apps: the only tool that connects ActivoBank, Revolut, and ING Spain into a single accurate picture is a multi-bank aggregator.

If you hold accounts across ActivoBank, Revolut, and ING Spain, you already know the problem. You open three apps, see three balances, and still have no idea what you actually spent last month. That is not a minor inconvenience — it is a structural blind spot in your finances.

Why Three Apps Are Not the Same as One View

Portugal’s household savings rate has held up, but individual behaviour tells a different story. When your salary lands in ActivoBank, your discretionary spending runs through Revolut, and your Spanish emergency fund sits in ING Spain, no single app shows you the full picture.

The core failure is transfers. Move €1,000 from ActivoBank to Revolut and most apps count it as spending in the first account and income in the second. Your reported expenditure is now €1,000 higher than reality. Multiply that across a year and the distortion is significant.

That is the problem aggregators exist to solve.

What a Real Aggregator Does Differently

A multi-bank aggregator connects to all three institutions via open banking — PSD2 in Portugal and Spain — and reads your transactions in one dashboard. The critical feature is transfer detection: the app identifies inter-account movements and strips them from your income and spending totals.

ActivoBank supports open banking connections through Millennium BCP’s infrastructure. Revolut exposes its data via its own API under PSD2. ING Spain participates in the Spanish open banking framework regulated by Banco de España. All three can be connected — but only if the aggregator has built integrations for all three.

Not every aggregator has done that work.

The Security Question You Should Ask Before Connecting

Open banking under PSD2 means read-only access. The aggregator sees your transactions and balances — it cannot initiate payments or move funds. This is a regulatory guarantee, not a product promise. Any aggregator operating under PSD2 in Portugal or Spain is legally prohibited from doing anything beyond reading data.

The risk is not the connection itself. The risk is aggregators that operate outside the PSD2 framework and use screen-scraping — storing your actual login credentials on their servers. Always verify the aggregator holds a Payment Institution licence from Banco de Portugal or the equivalent Spanish regulator. If they cannot show you that licence, do not connect your accounts.

Read-only, licensed, PSD2-compliant: those are the three requirements.

The Counterargument: Just Use Revolut as Your Hub

The strongest objection is this: Revolut already aggregates external accounts in some markets, so why not use it as the single view? It is a fair point. Revolut’s “Connected Accounts” feature does pull in some external banks.

The problem is coverage. In Portugal and Spain, Revolut’s external account connections are inconsistent — ActivoBank support has been intermittent, and ING Spain has had periods where the link dropped without warning. You also lose analytical depth: Revolut shows balances but does not strip inter-account transfers from its spending analysis. The distortion problem remains.

So What: How to Actually Set This Up

If your accounts at ActivoBank, Revolut, and ING Spain are generating three separate pictures of your money, here is what to do now.

If you want to see your combined balance and real spending without manually reconciling three bank exports, MyCFO aggregates all three automatically — transfers excluded, distortion removed.

“With 3 accounts across 2 countries, one undetected transfer error inflates your reported spending by €1,000 or more annually.”

Confirm your aggregator holds a PSD2 Payment Institution licence — check the Banco de Portugal or Banco de España registry directly.
Connect ActivoBank, Revolut, and ING Spain one at a time and verify each connection shows live transaction data, not just a static balance.
After 30 days, check that transfers between your own accounts appear as excluded or zero-impact in the spending summary — if they show as expenses, the aggregator is not stripping them correctly.
Set a monthly review: one number for total net income, one for total spending, one for net savings. If you need three apps to get there, the setup has failed.

One dashboard, three banks, no double-counting.

Frequently Asked Questions

Which app works with both ActivoBank and ING Spain at the same time?

Few aggregators have built PSD2 integrations for both simultaneously. ActivoBank operates under Millennium BCP’s open banking infrastructure, while ING Spain connects through the Spanish framework regulated by Banco de España. MyCFO connects to both, along with Revolut, in a single dashboard. Before committing to any aggregator, verify that all three connections show live transaction data — not just a static balance import.

How does having accounts at 3 different banks change what the app needs to do?

With a single bank, any budgeting app works adequately. With 3 accounts, the critical requirement changes: the app must detect and exclude inter-account transfers from income and spending totals. Without that feature, moving money between your own accounts inflates both sides of your budget. Multi-account users need an aggregator with explicit transfer-matching logic — not just a transaction list that happens to show multiple institutions.

Under PSD2, compliant aggregators use read-only access — they cannot initiate payments or store your credentials. The safety condition is the licence: your aggregator must hold a Payment Institution authorisation from Banco de Portugal or Banco de España. Screen-scraping tools that ask for your full login credentials are not PSD2-compliant and carry genuine credential-theft risk. Check the regulator’s public registry before connecting any account.

Managing your finances across ActivoBank, Revolut, and ING Spain means three data sources, three transfer distortions, and one missing number: what you actually spent. MyCFO connects all three accounts, detects inter-account transfers automatically, and strips them from your totals so the spending figure you see is real. Find out where you actually stand →
