What Is a mobile banking app?

A mobile banking app is a feature that allows you to access and manage your bank account easily from your mobile phone.

Apps are usually free and can be used on any smart device for most of your online banking needs 24/7. You can check your balance, transfer money, set up direct debits, and track your spending insights, for example.

Mobile banking apps are popular with app-only banks, but high-street banks also offer online banking and banking apps. You can download a banking app from your device's smartphone for free.

If you're looking for an app-only bank, we've some recommendations for the best mobile banking apps in the current market.

Digital-only banks, which have no physical branches, are rising in popularity due to their accessibility and the ease of opening a bank account with one. Digital-only banks also fall under the name of app-only banks, sometimes called challenger banks.

Online-only banking apps: pros and cons

Switching to app-only bank comes with ups and downs. This section explores the pros and cons of using mobile banking apps from digital-only banks.


✔️ Convenience: with online banking, you don't have to wait for an opening time to access your bank, you do all bank account management 24/7 from a mobile banking app

✔️ Time-saving: transactions on a mobile banking app are typically processed faster than traditional banking methods

✔️ Track expenses: you can see all your transactions as they happen and most banking apps will share your spending insights to help you control your money. Expense tracking is a great feature that most digital-only banks offer.

✔️ Budgeting features: most digital-only banking apps have budgeting features to help you stick with your monthly limit and not overspend

✔️ Separate savings accounts: you can often open savings accounts with an online bank. Some even let you open multiple so you can keep your money separate.

✔️ Financial Services Compensation Scheme (FSCS) protected: Most digital banks are FSCS-protected like traditional banks, protecting up to £85,000 of your money kept with one company.

✔️ Earn interest on account balances: when you open an app-based bank account, sometimes you can earn interest on your balance and interest on money in your savings account

✔️ Debit card: you'll usually get a debit card, but you may have to pay a delivery fee for it

✔️ Travel benefits: many app-only banks are ideal for people who travel a lot as they offer fee-free spending abroad


❌️ Absence of own ATMs: most app-only banks don't have their own ATMs, so you could be charged a fee when you withdraw cash from your current account.

❌️ No branches: there are no branches you can visit, however, a 24/7 support team or a virtual banking assistant is usually available if you ever need assistance with digital banking

❌️ You need a smartphone: digital banking requires a smartphone, so you'll need to own and use a smartphone to use a banking app

❌️ Limited credit options: with most digital-only banking, there are usually no credit options like overdrafts or loans

❌️ Deposit cash and cheques: as there are no branches, you may need to visit a Post Office to deposit cash and you may not be able to deposit cheques

How to choose the best banking app

There are lots of banking apps to choose from and here we've come up with a list of features to look out for:

  • Types of transactions: if you're looking for a digital-only bank account that does pretty much the same thing as an account from a high street bank, ensure the account can make basic transfers, direct debits, standing orders, and international payments.
  • User-friendly: you'll want a banking app that is easy to use, so look for a bank that prides itself on user accessibility. A user-friendly interface is a must for banking apps to be successful.
  • Support team: with no branches you'll want a digital bank with a reliable support team, that you can contact 24/7
  • Fees: keep an eye out for fees, some of these banks have cash withdrawal fees and foreign transaction fees

How do mobile banking apps work?

Most digital-only banks require you to download an app before applying for a bank account.

Once you have the app, and the account, you can do most of the things you can do with a traditional bank. These include the following:

  • Check account balances: you can check your account balance whenever you want.
  • Access online virtual banking assistant: if you need support, there is usually a team to help
  • Transfer money from your account: you can instantly transfer money to other bank accounts
  • Manage your bank accounts: if you have multiple accounts with one online bank, like a current account and a savings account, you can manage all of them in one place
  • Set up and manage direct debits: you can set up and manage direct debits from a mobile app
  • Track your spending: you can see what money goes in and out of your bank account and some apps provide spending insights to help you budget and improve spending habits

Downloading banking apps

You'll find bank apps by searching in your smartphone's App Store. It's always good to check on the bank's website if your smartphone device is compatible. Although most, if not all, banking apps are available for iOS and Android devices.

All mobile banking apps are free to download and use. Once you've downloaded the app, you must sign up for your bank account. You'll need documentation to verify your identity when signing up for a new bank account.

What you need to open an online bank account

When opening any bank account, there are certain documents that you need. To save you time, we've made a short list of the documents you need to open an account on a bank app.

You'll need the following information:

  • Proof of identity: you’ll need a passport or a driving licence. You can use a full driving licence or a provisional one.
  • Proof of address: you can use records dated within the last three months, such as utility bills, credit union statements, and Universal Credit statements.
  • Credit history: if you're taking out a line of credit with online banks, there may be a credit score requirement and credit check on your credit report.

One of the great features of digital-only banking apps is that you simply take a picture or scan your documents to verify your identity. Some apps may require a live portrait photo or video to match you with your photo I.D.

Typically, the overall process takes up to 15 minutes, and you'll find out if you're accepted usually on the same day. In some cases, you may not need to show your proof of address or your credit history.

Increase your online banking security

Banking apps are typically safe and secure. But if you're worried about someone stealing the information from your smartphone, there are additional security methods you can take to ensure further security of your bank accounts.

Increase security on your smartphone with the following tips:

  • Two-step verification: you can set up a two-step verification on your smartphone and payment apps. You can unlock your phone with a personalised PIN and biometric verification. Biometric verification requires a face scan or thumbprint to unlock the device. You can add these measures to most mobile apps, too, as well as your smartphone.
  • Vary passwords: sometimes, online data leaks can happen. The best way to avoid this is to vary your passwords. Using the same passwords repeatedly can put your data in harm's way. Ensure your passwords are varied to prevent them from being guessed.
  • Don't share pins or passwords: keep your pins and passwords to yourself. Make a note of your passwords somewhere no one else can access.
  • Smartphone insurance: you may want to insure your phone, either with a standalone insurance policy or through your home insurance
  • Delete banking emails and texts: avoid keeping emails or texts in your inbox containing private and essential information

Final thoughts

App-only banks are convenient for pretty much everyone, especially those who want to be able to control their money from their smartphone, no matter where they are in the world.

Our list of the best mobile banking apps is a good place to start, and the best one for you will depend on what you're looking for, be it a current account paying interest or an account with free cash withdrawals.

You can do most things from online bank apps; you can manage your money, work on your budgeting skills, and even contact a support team whenever you need but there are limitations too, such as paying for a card to be delivered and not being able to deposit cheques in some cases.
