Revolut and Monzo get lumped together constantly. Both have slick apps, both came up in the same wave of "challenger" finance companies, and both are genuinely good at the things people actually do with their phones: checking balances, splitting bills, freezing a lost card in two taps. But underneath the similar branding, they are structurally different products, and that difference matters more than most comparison articles let on.
I use both. I'm not here to tell you to pick one and delete the other — for a lot of people, running both makes sense. But you should understand what you're actually getting before you decide where your salary lands.
The structural difference nobody mentions enough
This is the bit that gets glossed over in most "which app is better" content, and it's the most important thing to understand.
Monzo Bank Ltd is a fully licensed UK bank. It's regulated by the Prudential Regulation Authority and the Financial Conduct Authority, and deposits are protected by the Financial Services Compensation Scheme (FSCS) up to £85,000 per person. If Monzo ever went under, that protection is what gets your money back, up to that limit, the same as it would with Barclays or NatWest.
Revolut's position in the UK has historically been different. For its core UK account, Revolut has operated as an e-money institution rather than a full bank, which means customer funds are typically safeguarded rather than covered by the FSCS. Safeguarding means your money is supposed to be held separately from Revolut's own funds, ring-fenced so it isn't used for the company's day-to-day operations. That's a real and meaningful protection, but it is not the same as the FSCS deposit guarantee, and the practical difference shows up if a firm ever runs into serious trouble.
I want to be clear this isn't a knock on Revolut as a company — they're a huge, established business with millions of UK users and no shortage of regulatory scrutiny. But "safeguarded" and "FSCS protected" are not interchangeable terms, and you should know which one applies to your money. Always check the current terms in the app, because licensing arrangements for fintechs do shift over time as companies expand their regulatory permissions.
Where each app actually wins
Strip away the safety question and you're left with two genuinely different feature sets aimed at slightly different habits.
Revolut's strength is multi-currency. If you regularly hold, spend, or exchange money in more than one currency — euros for a property abroad, dollars for freelance income, a holiday fund in three currencies at once — Revolut's setup is built for exactly that. You can hold balances in multiple currencies inside the app and exchange between them without going through a separate bank transfer. It also bundles in extras like crypto trading and stock trading that Monzo doesn't attempt to offer.
Monzo's strength is everyday UK banking done well. Round-up savings, shared "pots" for bills and goals, instant spending notifications, and a current account that behaves like an actual bank account because it is one. If your financial life is mostly in pounds, mostly in the UK, and you want your savings to sit somewhere with proper deposit protection, Monzo's structure does more of the heavy lifting for you.
Fees worth knowing about
Both apps offer free tiers that cover most casual use without monthly charges, and both make money on premium subscription tiers with extra features (higher cash withdrawal limits, travel insurance, metal cards, and so on).
For day-to-day spending abroad, both are competitive on foreign transaction fees compared to a typical high street debit card, which is one of the main reasons people pick up either app in the first place. Where it gets more nuanced is on things like out-of-hours currency exchange, ATM withdrawal limits on free tiers, and weekend exchange rate markups — details that change often enough that I'd rather point you to checking the current terms in-app than quote a number here that might be out of date by the time you read this.
A note on customer service and account stability
This is the other area where the two apps tend to diverge in people's actual experience, beyond the regulatory question. Monzo, being a full bank with a current account at its core, tends to behave predictably: salary in, direct debits out, a UK sort code and account number that work everywhere a UK bank detail is expected.
Revolut's structure occasionally creates friction in places that assume you're dealing with a conventional bank — some employers' payroll systems, some mortgage applications, and some older UK institutions are set up with traditional bank accounts in mind, and can be fussier about a Revolut account number in ways they wouldn't be about a Monzo one. It's not a dealbreaker, but it's worth testing before you commit your salary to either app exclusively, particularly if you know you'll need a mortgage or another credit-based product in the near future where the underlying account type might get scrutinised.
Account freezes and verification checks are something both apps have faced criticism for at points, as is common across digital-first finance companies that move quickly and scale fast. Neither is uniquely bad here, but it reinforces the same general point: don't make either app the sole place your money lives, especially if you can't afford a few days of restricted access while an issue gets resolved.
Practical setup: how I'd actually use both
If you're going to run both apps, which I think is the sensible default for most people who travel or deal with multiple currencies, here's roughly how I'd divide things up. Keep your main current account, salary, and the bulk of your emergency fund in Monzo, where the FSCS protection covers you properly. Use Revolut as your travel and multi-currency spending tool: top it up before a trip or when you need to hold a foreign currency balance, spend from it abroad, and avoid letting large amounts sit there for extended periods beyond what you need for the immediate purpose.
This gives you the best of both: the safety net of full UK banking for the money you can't afford to lose access to, and the flexibility of Revolut's currency tools for the spending that actually benefits from them. It's not about picking a winner. It's about understanding what each one is actually built to be good at, and not asking either app to do a job it wasn't designed for.
My take
If you want one clear answer: for most people's main current account and savings, Monzo's FSCS-backed structure makes it the more conservative, lower-risk home for the bulk of your money. For multi-currency spending, travel, and the extra features Revolut bundles in, it's a genuinely strong companion app.
What I wouldn't do is hold a large chunk of your savings in an e-money account purely because the app is nicer to look at. Use Revolut for what it's brilliant at — currency flexibility and spending abroad — and keep your core banking and savings somewhere with full FSCS protection. Running both isn't a compromise. For a lot of UK users, it's the optimal setup.
