Around 1 in 3 UK adults don’t use any form of budgeting tool, according to research from The Investors Centre. That means millions of people are managing their money without a clear picture of where it actually goes each month. For someone earning £30,000 a year, even a small monthly overspend of £50 adds up to £600 lost annually — money that could be sitting in a savings account or covering a bill.

Budgeting apps have moved beyond simple spreadsheets. Many now connect directly to your bank account through Open Banking, automatically sort your spending into categories, and even move money into savings pots without you lifting a finger. But with so many options — from free apps to premium plans costing nearly £40 a month — it’s easy to pick one that doesn’t fit how you actually spend. Here’s what you actually need to know.
What the best budgeting tools actually do differently
The central concept here is Open Banking — a regulated system that lets apps read your transaction data (with your permission) without you handing over your login details. It’s what makes modern budgeting tools feel automatic rather than a chore.
What I tend to notice is that people pick an app based on its flashiest feature — AI savings, say — without checking whether it handles the basics well. A tool that auto-categorises your spending but doesn’t let you set custom budgets might leave you just as in the dark as before. Worth weighing the core function against the extras.
What each budgeting tool actually costs — and what you get
Pricing varies wildly across the UK budgeting app market. Some are genuinely free at the basic tier. Others charge £15 a month or more for features like unlimited accounts, future projections, or multi-currency support. The table below shows what the main apps charge and what changes between tiers.

| App | Free tier | Paid tier (per month) | Key paid feature |
|---|---|---|---|
| Emma | Yes | £4.99 – £14.99 | Unlimited accounts, net worth tracking |
| Plum | Yes | £2.99 – £9.99 | Automated savings, interest-bearing pots |
| PocketSmith | Yes | £14.95 – £39.95 | Future cashflow projections, unlimited accounts |
| Monzo | Yes (banking) | £5 – £15 | Savings pots, spending insights, cashback |
| Revolut | Yes | £4.99 – £26.66 (annual) | Multi-currency, budgeting, virtual cards |
| Starling | Yes (banking) | Free | Spending categories, savings goals |
| Koody | Yes | Free | Manual budgeting, no bank connection |
Notice the range. PocketSmith at £39.95 a month is a serious commitment — you’d want to be using its projection tools regularly to justify that. Meanwhile, Starling and Koody stay free, but Starling is a full bank account with budgeting built in, while Koody is a manual tracker with no bank link at all. The right choice depends on whether you want automation or control.
For someone earning £35,000, paying £15 a month for a premium app is £180 a year. If that app helps you cut £30 a month in forgotten subscriptions, it pays for itself. If you’re already on top of your spending, a free tier probably does the job.
Where people get budgeting apps wrong
Picking an app that doesn’t connect to your bank
Manual entry apps like Koody work fine if you’re disciplined about logging every coffee and train fare. But most people stop after a week. If you know you won’t keep up with manual tracking, choose an Open Banking app like Emma or Monzo that pulls data automatically. Otherwise you’re paying for a tool you won’t use.
Ignoring the account connection limit on free plans
Several free tiers cap you at one or two bank accounts. If you have a current account, a joint account, and a credit card, you might not be able to link them all without upgrading. That means your budget shows an incomplete picture. Check the limit before you commit — it’s often buried in the small print.
Assuming all savings features are the same
Plum’s automated savings move money based on what it thinks you can afford. Monzo’s savings pots are more manual — you set the rule. Neither is better, but they suit different habits. If you want a hands-off approach, Plum’s AI might work. If you prefer to decide exactly how much goes where, Monzo’s pots give you more control.
Overlooking foreign transaction fees on banking apps
Revolut and Monzo both offer fee-free spending abroad up to a limit — typically £200 per month in free ATM withdrawals. After that, you pay a 1% currency conversion charge on weekend spending. If you travel regularly, those charges add up. A dedicated travel card might be cheaper than relying on your budgeting app’s built-in banking feature.
How to choose and set up the right budgeting tool for your situation
Decide between a banking app and a standalone tracker
Monzo and Starling are full current accounts with budgeting features built in. You move your main banking to them. Emma and PocketSmith sit on top of your existing bank — they read your data but don’t hold your money. If you’re happy with your current bank, a standalone tracker avoids the hassle of switching. If you want everything in one place, a banking app simplifies things. A savings app comparison can help you weigh the trade-offs.
Set up your categories and budgets before the first month ends
Most apps auto-categorise spending, but the defaults are rarely perfect. A payment to Tesco might land in “Groceries” when it’s actually a meal out. Spend 15 minutes in the first week re-categorising transactions. That one-off effort makes the ongoing tracking far more accurate. If you skip this step, your “spending insights” will be misleading.
Use future projections to spot cashflow crunches
PocketSmith’s main strength is showing you your balance weeks or months ahead based on scheduled bills and income. If you have irregular income — freelance work, commission, seasonal bonuses — this is more useful than a simple monthly budget. You can see that December will be tight before it arrives and adjust spending in November accordingly.
Check what happens with joint accounts and shared finances
Starling is one of the few apps that handles joint accounts well — you can open a joint account with budgeting built in. Most standalone trackers let you link a joint account, but the spending shows up under one person’s profile. If you manage money as a couple, check whether the app supports shared budgets before you commit.
Watch for upcoming changes to Open Banking rules
The FCA is consulting on changes to Open Banking that could affect how apps access your data. As of 2026, the current system remains stable, but future rules might require apps to re-authenticate connections more frequently. That could mean occasional interruptions to automatic tracking. Keep an eye on your app’s updates — if a connection drops, you might need to re-link your account.

The real test is whether you still use it in three months
Downloading a budgeting app is easy. Sticking with it is where most people fall off. The research from The Investors Centre tested over 40 platforms with real money, and the apps that scored highest weren’t necessarily the cheapest — they were the ones people actually kept using. That’s the only metric that matters for your finances. An app you ignore is worse than no app at all.
