YNAB is the best-known zero-based budgeting app, but it was built for the US, is priced in US dollars and connects directly to only some UK banks. This guide sets out how five UK apps work and what they cost, so you can compare them against the one thing you actually want help with.
| Tool | Best For | Rating |
|---|---|---|
| Delphina | Long-term financial clarity | ★★★★★ |
| Emma | Automatic transaction categorisation | ★★★★★ |
| Moneybox | Savings and investing | ★★★★★ |
| Plum | Automated savings | ★★★★★ |
| Snoop | Tracking spending and cutting bills | ★★★★★ |
YNAB is excellent but it was designed for the US market. Here is what to look for in a UK alternative.
Know where you are. Change where you are going.
Delphina focuses on the question most budgeting apps ignore: not where your money went, but whether your wealth will last. It projects your financial future over decades, showing whether your current trajectory will support the retirement and life you want. Unlike YNAB which focuses on categorising past spending, Delphina shows you what your financial future looks like and what changes would make the most difference.
Smart money management
Emma connects to your UK bank accounts and automatically categorises your transactions, making it easy to see where your money goes each month. It offers spending insights, bill tracking, and alerts for unusual activity. The app is particularly strong at identifying subscriptions and helping you cancel ones you no longer need. It is one of the most popular UK alternatives to YNAB for everyday budget tracking.
Build wealth for what matters
Moneybox is a UK-focused app that combines everyday savings with longer-term investing. It offers Cash ISAs, Lifetime ISAs, Stocks and Shares ISAs, and personal pensions. The app rounds up everyday purchases and invests the difference, making it easy to save without thinking about it. It is best for people who want to build wealth gradually without needing to manually categorise every transaction.
Automated saving and investing
Plum links to your current account through Open Banking with read-only access, looks at your spending and moves small amounts into savings automatically. It also offers easy access savings, a Cash ISA, a Stocks and Shares ISA and a personal pension (SIPP). There is a free Basic plan, with paid plans from £3.99 to £14.99 a month. It is a saving and investing app rather than a budgeting tool.
Spending, bills and budgets in one app
Snoop connects your UK bank accounts and credit cards through Open Banking to track spending by category and merchant, flag bill increases and spot subscriptions. You can set monthly budgets yourself or let the app suggest them, and it includes a free credit score. The core app is free; Snoop Plus costs £5.99 a month or £47.99 a year. Snoop is registered with the FCA under the Payment Services Regulations 2017.
YNAB is a retrospective budgeting tool. It focuses on giving every pound a job before you spend it, then tracks what you actually spent. This is excellent for cash flow management and building savings discipline.
But YNAB does not answer the question that matters most for your future: will my wealth actually last?
Delphina is prospective. It takes your current financial position, your expected income paths, and shows you where you are headed over the next 10, 20, 30 years. It answers whether you are on track for retirement, whether your savings rate is sufficient, and what changes would have the biggest impact on your future financial security.
YNAB focuses on budgeting. Delphina focuses on your complete financial future. They serve different purposes, and many people benefit from using both.
Delphina is not a budgeting tool like YNAB. If you want zero-based budgeting, where every pound has a job and you actively allocate income to specific categories before spending, YNAB is the right tool for that specific purpose.
If you want to know whether your wealth will last, whether you are saving enough for the life you want, and what your financial future actually looks like, that is what Delphina is for.
Think of it this way: YNAB helps you manage your money month to month. Delphina helps you understand whether your money will manage to support the life you want over decades.
YNAB works in the UK, but it was built for the US market, is priced in US dollars and connects directly to only some UK banks. The UK apps in this list each take a different approach. Emma and Snoop link to your bank accounts through Open Banking to track and categorise spending. Plum moves money into savings automatically. Moneybox is built around saving and investing, including round-ups from a linked current account. Delphina shows your whole financial picture from statements you upload, rather than from a bank connection.
If zero-based budgeting is the method you want, giving every pound a job before the month starts, YNAB is the app built around it. If instead you want to see where your money goes, save automatically or know whether you are on track overall, decide which of those jobs matters most to you. Then compare what each app does and costs for that job before you sign up.
If your goal is to understand whether your wealth will actually last through retirement, whether you are on track for the life you want, and what changes would have the biggest impact on your financial future, Delphina is built specifically for that question.
