8 Best Free Budgeting Apps
UK 2026: Honest Reviews

Budgeting apps have become genuinely useful in the UK over the past few years. Open Banking regulation means apps can now connect directly to your bank accounts, read your transactions, and categorise your spending automatically. That is a huge step up from manually typing expenses into a spreadsheet. But with so many options, choosing the right one is harder than it should be. Some apps are brilliant at one thing and weak at everything else. Some lock their best features behind paywalls. Some only work if you bank with them directly.

We tested all eight of these apps on real UK bank accounts and evaluated them on what they actually deliver for free. If you are looking for a broader guide on how to structure your salary once you have a budgeting tool in place, our guide on how to budget your salary in the UK covers the allocation side in detail.

1. Monzo: Best Free Budgeting for Existing Monzo Users

Monzo deserves the top spot for anyone who already banks with them. The budgeting features built into the Monzo app are genuinely excellent and completely free. You get automatic spending categories that are surprisingly accurate, the ability to set monthly budgets per category, and Salary Sorter, which lets you split your pay into different pots the moment it arrives. Pots are Monzo's standout feature for budgeting. You can create separate pots for rent, bills, savings, and spending money, then set up scheduled payments so the right amount goes to the right pot every payday. It turns your single current account into something that works more like a proper allocation system.

The free tier also includes spending summaries, merchant categorisation, and instant notifications for every transaction. Monzo Plus at £5 per month adds credit score tracking, custom categories, and interest on balances. Monzo Premium at £15 per month adds travel insurance, metal card, and higher interest rates. But for basic budgeting, the free account is genuinely sufficient.

The limitation is significant: Monzo's budgeting tools only work with money inside your Monzo account. If you have a joint account with another bank, a credit card with Barclays, or savings with a building society, Monzo cannot see any of that. You get a brilliant view of one account, but no visibility across your full financial picture. For people who keep everything in Monzo, that is fine. For anyone with multiple banks, it is a real constraint. If multi-bank visibility matters to you, see our roundup of the best budgeting apps in the UK where we compare aggregators specifically.

2. earmarkIQ: Best for AI-Powered Salary Allocation

earmarkIQ takes a different approach from most budgeting apps. Rather than simply categorising your past spending, it focuses on what happens to your salary the moment it arrives. The app connects to over 50 UK banks via Open Banking, pulls in all your transactions across every account, and uses AI to build a complete financial profile. From there, it generates a personalised salary allocation plan that tells you exactly how much should go to bills, savings, investing, and discretionary spending each month.

The free tier includes Open Banking aggregation across all your connected banks, AI-powered transaction categorisation, subscription tracking with price creep detection, and a basic salary allocation. That is a genuinely generous free offering. The Plus tier at £4.99 per month adds deeper AI insights and the Ask IQ financial advisor (powered by Claude from Anthropic). Pro at £9.99 per month adds capital gains tracking and salary sacrifice optimisation. Unlimited at £14.99 per month removes all limits.

What sets earmarkIQ apart from other apps on this list is the AI categorisation. Rather than relying on merchant codes alone, earmarkIQ uses machine learning to understand your spending patterns, identify your "money personality," and spot opportunities you would not find yourself. It also detects subscription price creep automatically, alerting you the moment any recurring payment increases. For a deeper look at why subscription tracking matters, see our full guide on how to stop wasting money on subscriptions.

earmarkIQ is an FCA Appointed Representative of Finexer Ltd (FRN 925695) and ICO registered, which means it operates under the same regulatory framework as the banks it connects to. The app uses read-only Open Banking access by default and bank-grade encryption for all data.

The honest limitation: earmarkIQ is iOS only at launch and is newer to the market than established players like Emma or Monzo. The app launched in 2026, so it does not have years of historical data or the polish that comes from thousands of iterations. If you want something battle-tested with a large user community, Emma has been doing this longer. If you want the most advanced AI features and multi-bank salary allocation, earmarkIQ is the stronger choice.

3. Emma: Best Established Multi-Bank Tracker

Emma has been one of the most popular multi-bank budgeting apps in the UK for several years, and it has earned that reputation. The free tier connects to your banks via Open Banking, categorises your spending, and tracks your subscriptions. Emma was one of the first UK apps to offer subscription detection, and it does it well. You get a clear list of all recurring payments, their frequency, and their annual cost.

The app also provides a net worth tracker, spending analytics by category, and merchant-level spending breakdowns. The interface is clean and well designed, with a feed-style layout that makes it easy to scroll through transactions across all your accounts in one place. Emma has been through years of refinement, and the overall experience is polished in a way that newer apps have not yet matched.

Emma Plus at £4.99 per month adds custom categories, budgets, and bank fee detection. Emma Pro at £9.99 per month adds investing tracking and export features. Emma Ultra at £14.99 per month adds priority support and all features unlocked. The pricing tiers are competitive and comparable to earmarkIQ's structure.

The limitation with Emma is that its AI features are more limited than what earmarkIQ or even Plum offer. Emma does a very good job at showing you what happened with your money, but it is less proactive about telling you what to do next. It categorises and tracks, but the intelligent allocation and predictive features are thinner. Some useful features, like custom categories and detailed budgets, sit behind the paywall. If you want the most established multi-bank tracker with years of reliability, Emma is the safest choice. If you want more intelligence and automation, you may find it a bit passive.

4. Snoop: Best for Bill Switching and Savings Tips

Snoop positions itself as the app that helps you save money rather than just track it. It connects to your bank accounts via Open Banking and analyses your bills and subscriptions, but its real strength is in actionable recommendations. Snoop scans your energy bills, broadband, insurance, and mobile contracts, then tells you whether you could get a cheaper deal elsewhere. In some cases, it can facilitate the switch directly within the app.

The free tier includes spending insights, bill comparison, switch suggestions, and basic spending categories. There is no paid tier in the traditional sense; Snoop monetises through referral fees when users switch to recommended providers. This means the entire app is free to use, which is genuinely appealing. You get useful features without ever being asked to upgrade.

Snoop also provides weekly insights emails that summarise your spending and highlight potential savings. These are surprisingly practical and more useful than the push notifications most apps send. The app has a friendly, accessible design that avoids the complexity some competitors lean into.

The limitation is that Snoop's spending categorisation is less detailed than Emma or earmarkIQ. It is not trying to be a comprehensive financial dashboard. If you want a full picture of your net worth, detailed category-level budgets, or AI-powered salary allocation, Snoop is not the right tool. It excels at one thing: finding ways to cut your bills. If that is your primary goal, Snoop is the best free option in the UK by a clear margin. If you want broader budgeting, you will need to pair it with another app.

5. Plum: Best for Automatic Micro-Saving

Plum takes an unusual approach. Rather than focusing on budgeting in the traditional sense, it uses AI to analyse your spending patterns and automatically move small amounts of money into savings when it calculates you can afford it. The algorithm learns your income and spending rhythm, then makes regular transfers to your Plum savings account in amounts small enough that you do not notice them missing, but large enough to accumulate meaningfully over time.

The free tier includes AI-powered automatic saving, round-ups on purchases, basic investing with access to a small number of funds, and spending insights. Plum Plus at £2.99 per month adds higher interest on savings and more investment options. Plum Pro at £4.99 per month adds unlimited investment portfolios, cashback, and advanced analytics. The entry-level paid tier is the cheapest on this list, which makes the upgrade easier to justify.

For people who struggle to save consistently, Plum is arguably the most effective app here. It removes the decision-making entirely. You do not have to remember to transfer money or decide how much to save. The AI does it for you based on what you can genuinely afford. Over a year, users regularly report saving £500 to £1,000 without feeling the impact on their day-to-day spending.

The limitation is that Plum is more of a savings app than a full budgeting tool. It does not provide the detailed spending categories, salary allocation, or subscription tracking that apps like earmarkIQ or Emma offer. If you want to understand exactly where your money goes each month and build a structured budget, Plum will not give you that. It is a brilliant complement to a budgeting app, but it is not a replacement for one. Many people use Plum alongside another app on this list, which is a perfectly valid approach.

6. Revolut: Best for International Spending

Revolut started as a travel money card and has grown into a full digital bank with over 35 million users globally. The budgeting features are part of a much larger financial product that includes multi-currency accounts, stock trading, crypto, and insurance. For the purposes of this review, we are focusing on the budgeting-specific features available on the free Standard plan.

The free tier gives you spending analytics broken down by category and merchant, the ability to set monthly budget limits for different spending categories, instant transaction notifications, and basic savings vaults. You can also see your spending trends over time and compare month-to-month performance. Revolut Plus at £3.99 per month adds buyer protection and disposable virtual cards. Premium at £7.99 per month adds travel insurance, airport lounges, and higher limits. Metal at £14.99 per month adds cashback and concierge services.

For anyone who spends internationally, whether through travel, online shopping in foreign currencies, or sending money abroad, Revolut is the clear winner. The multi-currency wallet, competitive exchange rates, and lack of foreign transaction fees make it the best option for people whose spending crosses borders regularly.

The limitation is that Revolut's budgeting analytics are basic compared to dedicated budgeting apps. The spending categories exist, but they lack the depth and intelligence of what Emma, earmarkIQ, or even Monzo provide. Revolut is trying to be everything: a bank, a trading platform, a travel card, and a budgeting tool. The budgeting piece works, but it is clearly not the core focus. If budgeting is your primary need and you do not spend internationally, you will get a better experience from an app that focuses specifically on budgeting.

7. HyperJar: Best for Envelope-Style Cash Management

HyperJar takes the old envelope budgeting method and brings it into a digital format. The concept is simple: you load money onto your HyperJar account and then divide it into virtual jars for different spending categories. One jar for groceries, one for entertainment, one for the car, one for savings. When you spend from a jar using the HyperJar card, the money comes out of that specific jar. When a jar is empty, you know you have hit your limit for that category.

The entire app is free. There are no paid tiers. HyperJar monetises through partnerships with retailers who offer discounts when users allocate money to brand-specific jars. For example, you might get a percentage bonus if you put money into a "Tesco" jar and then spend it at Tesco. This model means you never pay for the app, and you can earn retailer discounts simply by planning your spending.

HyperJar also supports shared jars, which are useful for couples, housemates, or families who share certain expenses. You can create a jar for household bills, invite others to contribute, and track shared spending transparently. The visual, jar-based interface is intuitive and works well for people who find traditional budgeting apps overwhelming.

The limitation is that HyperJar is not a full Open Banking aggregator. It does not connect to your existing bank accounts and pull in transactions the way earmarkIQ, Emma, or Snoop do. You have to load money onto the HyperJar account manually, which adds friction. It also means HyperJar cannot give you a complete picture of your finances. It manages the money you put into it well, but it has no visibility into spending on your main bank account or credit cards. For people who want one app that shows everything, HyperJar is not the right choice. For people who like the discipline of physically separating money into categories, it is excellent.

8. YNAB: Honourable Mention (Free Trial Only)

YNAB (You Need A Budget) is not truly a free budgeting app, which is why it is listed as an honourable mention rather than a direct recommendation. It offers a 34-day free trial, after which the subscription is $14.99 per month (approximately £12 per month at current exchange rates). That makes it the most expensive option on this list by some distance. However, YNAB's budgeting methodology is so effective that it deserves inclusion for anyone willing to pay for it.

YNAB's approach is based on four rules: give every pound a job, embrace your true expenses, roll with the punches, and age your money. This methodology forces you to be intentional about every pound you earn, assigning it to a specific purpose before you spend it. Users who commit to the system regularly report transformative changes in their relationship with money. The YNAB community is passionate and supportive, with active forums, workshops, and educational content.

The app itself is well designed with goal tracking, detailed reports, and the ability to share budgets with a partner. YNAB also has a strong track record: the company has been operating since 2004, and the methodology has been refined over two decades.

The limitations for UK users are significant. YNAB does not support UK Open Banking. While it offers some direct bank connections in other countries, UK users typically need to import transactions manually or use CSV uploads. This adds considerable friction compared to apps like earmarkIQ or Emma, which connect to your banks instantly and pull transactions automatically. The pricing is in US dollars, which means your effective cost fluctuates with the exchange rate. And at roughly £12 per month, it is the most expensive option here. For the price, you get a brilliant methodology but a less convenient UK experience. If you are disciplined enough to enter transactions manually and you value the YNAB approach, it is worth the trial. For most UK users who want a "connect and forget" experience, the Open Banking apps above will be more practical.

How to Choose the Right Budgeting App for Your Situation

The best budgeting app depends entirely on what you actually need. There is no single winner for everyone, which is precisely why we ranked these in the order we did rather than placing one app above all others.

If you already bank with Monzo and keep most of your money there, start with the built-in tools. They are free, well designed, and require zero setup. You do not need a third-party app if Monzo is your only bank. Salary Sorter and Pots together give you a simple allocation system that works the moment your pay arrives.

If you have accounts across multiple banks, which most UK professionals do, you need an app with Open Banking aggregation. earmarkIQ, Emma, and Snoop all connect to multiple UK banks and give you a single view of your finances. Among these, earmarkIQ offers the most advanced AI features and is the only one that builds a full salary allocation plan automatically. Emma offers the most mature and polished experience. Snoop is the strongest at finding bill savings. Your choice between them depends on whether you value AI-driven recommendations, a proven track record, or actionable savings tips.

If your main problem is not budgeting but saving, Plum is the most effective tool. Its automatic saving algorithm removes the willpower from the equation and quietly builds your savings without you having to think about it. Pair it with a budgeting app like earmarkIQ or Emma for the complete picture.

If you spend frequently in foreign currencies, Revolut is essential. Its multi-currency features and competitive exchange rates are unmatched. But use it alongside a dedicated budgeting app if you want proper spending categorisation and budget management.

If you like the discipline of physically separating your money into categories and you prefer a visual approach to managing cash, HyperJar's jar system is simple and effective. The retailer discounts are a nice bonus. Just be aware that you will not get automatic bank connections or a complete financial overview.

If you are serious about methodology and do not mind manual data entry, YNAB's four-rule system is the most effective budgeting framework available. The 34-day free trial is enough to know whether it clicks for you. The lack of UK Open Banking is a real inconvenience, but YNAB users tend to view manual entry as a feature rather than a bug: it forces you to engage with every transaction.

Whatever you choose, the most important step is choosing something. Any app on this list will give you more visibility into your finances than managing money from your banking app alone. The UK's Open Banking infrastructure makes it easier than ever to connect your accounts and get a clear picture of your spending. The hard part is not finding the right app. The hard part is looking at the numbers and deciding what to change.
