Mobile-only banks (and EMI/financial apps) are transforming personal banking, offering an alternative to traditional brick-and-mortar banks with fast, secure and easy-to-use apps for iOS and Android. Mobile banks offer competitive banking services such as current accounts, savings accounts, loans, insurance, and debit/credit cards, often at a lower cost than traditional banks.
Mobile-only banks, also known as digital banks or challenger banks, should not be confused with an online account from your traditional bank. Mobile-only banks are fully app-based, offering more transparency and convenience with fewer restrictions and shorter waiting times than your everyday bank. And with millions of users across Europe and the UK already using mobile banks, it is clear that mobile-only banking apps are the future for hassle-free, borderless banking.

What is a Mobile Bank?
Why Use a Mobile Bank
24/7 availability
No matter where you are, at home or abroad, you can access your bank account via the app, check your account balance, control your savings, get customer support, make payments and even lock your debit card if needed. In addition, get real-time notifications every time you make a transaction, so there are no surprises at the end of the month. No need to make appointments, stand in line or lose working hours to manage your finances.
Get approved quickly
Opening an account with a mobile-only bank is simple, with no heavy paperwork. Just download the app, verify your identity, top up your account and you’re ready to go.
Lower fees
Another main reason to use a mobile bank is the low (or even no) fees. As a mobile-only platform with no physical branches, mobile banks can offer lower fees than traditional banks — especially for cashpoint withdrawals, currency exchange, transfers, and overseas payments.
Makes travel easier
Mobile banks = borderless banking. Low exchange rates and low or no ATM withdrawal fees worldwide make travelling a whole lot easier (and cheaper) than with traditional banks – especially in the eurozone. And for added safety, lock or unlock your debit card while you travel, directly in the app.
Go paperless
One of the frustrating things about traditional banks is the amount of documents, contracts and letters that are sent to your mailbox. With mobile banks everything you need is in the app and all communications are sent to your app or your email. Gone are the days of rummaging through piles of paper around your house – and helping the environment is the icing on the cake.
Fast loans
Unlike traditional banks, some mobile banks offer loans with a much simpler process. In most cases, if you apply for a loan and are approved, your funds will be transferred to your bank account within minutes of approval.
Comparing Mobile Banks
To compare mobile banks and find the right app for your banking needs, there are a number of factors you should consider:
Transaction & ATM fees
Although all mobile banks offer lower fees than traditional banks, there are still differences between each mobile provider. You may also wish to check other fees such as card replacement, overdraft and top-up fees before selecting your preferred mobile bank.
Monthly plans
The leading mobile banks offer a free account, so you only have to pay a small fee for the services you use. Many mobile banks also offer premium plans, offering additional benefits such as free withdrawals, lower foreign-transaction fees, insurance and more.
Savings & budgeting
Some mobile banks offer stand-alone savings accounts, while others offer helpful features such as rounding up your purchases and placing the difference in a ‘savings pot’ in the app, as well as budgeting goals and targets.
Security
The leading mobile banks, including those on this website, adhere to the highest safety standards, ensuring your money and data are protected around the clock. The mobile banks compared and reviewed by top10mobilebanks.com are authorised and regulated by local authorities.
Payments
All mobile banks offer a debit card for payments and withdrawals from your mobile bank account. In addition, many banking apps also offer digital wallets such as Google Pay or Apple Pay, making online and in-store payments even easier.
