A budgeting app works better for most people because it pulls in transactions automatically, so the budget stays up to date with almost no effort. A spreadsheet works better if you want complete control, have unusual income or costs, or do not want to share bank data with a third party. The best choice is the one you will still be opening in three months, and many people end up using both.
This guide compares the two honestly, explains how UK open banking apps handle your data, and gives you a two-week test to settle it. If you already know you want an app, our guide to the best budgeting apps in the UK compares specific options.
The short comparison
| Factor | Spreadsheet | Budgeting app |
|---|---|---|
| Cost | Free (Google Sheets, Excel for the web) | Often free, with paid tiers for extra features |
| Effort each week | Manual entry or CSV import | Mostly automatic; you fix categories |
| Flexibility | Unlimited: any layout, any formula | Limited to the app's categories and reports |
| Data sharing | Stays with you | Read-only bank access via open banking |
| Mobile use | Clunky on a phone | Built for it |
| Longevity | Yours forever | App may change, charge or close |
When a spreadsheet is the better choice
Spreadsheets reward people who like to understand exactly where every number comes from. They suit you if:
- Your income is irregular, for example self-employed, freelance or shift-based, and you need to plan by month or by tax year rather than by payday.
- You use a method apps do not support well, such as zero-based budgeting with your own categories, or sinking funds with different target dates.
- You want to plan ahead, not just record the past: a spreadsheet can model next year's council tax rise, a pay rise or a remortgage in a few cells.
- You prefer not to connect your bank to a third-party service.
- You enjoy the ritual. Typing in each transaction makes you notice it, which some people find is the point.
When an app is the better choice
The biggest reason budgets fail is that people stop updating them. Apps remove most of that work. They suit you if:
- You have tried a spreadsheet before and abandoned it within a few weeks.
- You spend mostly by card, so almost every transaction shows up automatically.
- You have several accounts or credit cards and want one view of them all.
- You want alerts, for example when a subscription renews, a bill goes up or you are close to a category limit.
- You check money on the go rather than at a desk.
How UK budgeting apps access your bank data
Most UK budgeting apps use open banking. You choose your bank in the app, log in through your bank's own app or website, and give permission for the budgeting app to read your transactions. The app never sees your banking password and, for an account information service, cannot move money.
Points worth knowing before you connect:
- Check regulation: providers of account information services must be authorised or registered by the Financial Conduct Authority. You can search the FCA register for the company name.
- Access is time-limited: you will usually be asked to reconfirm the connection every 90 days. If you ignore the prompt, transactions stop syncing.
- You can withdraw access at any time from the app, and usually from your bank's app too.
- Read the privacy policy: some free apps make money by showing offers based on your spending. Decide whether you are comfortable with that.
The hybrid approach most people end up with
Many long-term budgeters use an app for tracking and a simple spreadsheet for planning. The app answers "where did my money go this month?" without effort. The spreadsheet answers "what should happen next year?", holding annual costs, savings targets and big decisions. A practical split:
- App: daily transaction tracking, category totals, bill and subscription alerts.
- Spreadsheet: annual budget, sinking fund targets, net worth once a quarter (or use the net worth calculator).
- Habit tool: for building a saving streak, SYM tells you how much to put aside each day and logs it with one tap, without linking to your bank.
A two-week test to decide
Instead of debating, try both. For week one, record every transaction in a basic spreadsheet with four columns: date, amount, category, note. For week two, connect your main current account to a free budgeting app and only fix wrong categories. At the end, ask which one you kept up with without forcing yourself, and which one changed a decision (skipping a takeaway, cancelling a subscription). Choose that one. Our spending tracking guide has more on what to look for in your first fortnight of data, and how to budget for beginners covers setting the budget itself.
