PoundWise Team: A budgeting app can automatically sort transactions into categories, show where your money is going and help you set spending limits. Before linking a bank account, check the app’s privacy policy, fees, security measures and which permissions you are granting. If it uses open banking, check that the relevant account-information provider is authorised or registered with the FCA, and review or withdraw access when you no longer need it. Manual entry is another option if you prefer not to connect your accounts, although it requires regular updates.
