Most budgeting apps available in Cardiff are the same as those offered across the UK, so look for features that match your needs rather than choosing one based on location. Useful tools include automatic spending categories, bill reminders, savings goals and secure Open Banking connections, but check fees, privacy terms and whether your bank is supported. A free spreadsheet or bank app may be enough if you only need basic tracking. Before linking accounts, check that any Open Banking provider is authorised by the FCA and contact your bank if you notice anything unusual.
