Emma, Snoop and Plum get lumped together as “budgeting apps”, but they are built for three different jobs. One is a spending tracker that pulls all your accounts into one screen. One is a bill-cutting and money-saving assistant. One is an automatic saver that quietly moves spare change out of your current account before you spend it. Pick the wrong one and you will end up paying a few quid a month for features you never touch.

This guide compares all three on what they actually do, what they cost in 2026, and the kind of person each one suits. Prices and features below were checked against each provider’s own plans pages in May 2026.

What each app is really for

Emma is a money tracker first. It uses Open Banking to link your current accounts, credit cards, savings and investments, then shows everything in one feed. Its strengths are spotting subscriptions you forgot about, categorising spending and giving you a single net worth figure. Emma is built by Emma Technologies Ltd and is FCA registered (firm reference number 794952). The connection is read-only, so the app can see your transactions and balances but cannot move your money.

Snoop is a money-saving assistant. It also links your accounts through Open Banking and categorises spending, but its real focus is cutting your bills and flagging waste: a direct debit that just went up, a free trial about to start charging, a cheaper energy or broadband deal based on what you currently pay. Snoop was founded in 2019 by former Virgin Money chief executive Dame Jayne-Anne Gadhia and has been owned by Vanquis Banking Group since 2023. It is run by Usnoop Limited and is FCA registered (firm reference number 911638).

Plum is an automatic saver. Instead of just showing you your money, it moves it. Plum analyses your income and spending and skims small, affordable amounts into a savings pot every few days. It also does round-ups (a £4.50 coffee rounds to £5, and the 50p goes into savings) and payday deposits timed to when you get paid. On top of saving, Plum offers a Cash ISA, easy-access savings and investing in funds and stocks on its paid tiers.

In one line: Emma shows you the money, Snoop helps you cut the bills, Plum saves the money for you.

Pricing compared

This is where the three really separate. All have a usable free tier, but the paid plans are priced and structured very differently.

Emma has four tiers:

  • Free: links up to 2 accounts, with basic budgeting and categorisation
  • Plus: £4.99/month (£41.99/year), adds more account links, budgeting tools, web access, fraud detection alerts and savings pots
  • Pro: £9.99/month (£83.99/year), adds unlimited account links, cashback, rent reporting to Experian and net worth tracking
  • Ultimate: £14.99/month (£124.99/year), adds rent reporting to all three credit reference agencies, extra members and a VPN

Paying annually saves roughly 30% versus monthly.

Snoop keeps it simple:

  • Free: account linking, spending tracking, bill and subscription insights, switching deals and a free credit score
  • Snoop Plus: £5.99/month or £47.99/year, adds custom budgets and payday-to-payday tracking

Plum restructured its plans in mid-2025 and now runs four monthly tiers, with no annual billing option:

  • Basic: free, with 6 automation rules and access to its savings accounts
  • Plus: £3.99/month, adds 10 automations, the Plum debit card and spend insights
  • Boost: £7.99/month, adds investing in a range of curated funds
  • Max: £14.99/month, adds commission-free stock trading and the highest savings rate

A practical point on Plum: its headline interest rates change by tier. At the time of writing the Cash ISA was advertised at 4.60% AER (variable) across all plans, while easy-access savings rates rose with the more expensive tiers. Always check the live rate on Plum’s plans page before you sign up, because variable rates move.

How the budgeting actually works

If your main problem is “I have no idea where my money goes”, the budgeting experience matters more than the price.

Emma gives you the most detail. You can set budgets per category, split shared transactions, rename and re-categorise spending, and tag transactions. The subscriptions view is genuinely useful for catching the £9.99 here and £12 there that quietly drains an account. The trade-off is that the free tier only links two accounts, so anyone with a current account, a credit card and a savings account will hit that wall quickly and be nudged towards a paid plan.

Snoop does less manual budgeting and more automatic nudging. Rather than asking you to build a budget from scratch, it watches your accounts and sends short alerts: a bill rising, a refund landing, or a subscription you might not be using. Custom budgets sit behind Snoop Plus, but the free tier’s bill-cutting suggestions are the main reason to install it. If you want a money app that occasionally finds you cash rather than one you have to log into and manage, Snoop is the easiest of the three to leave running in the background.

Plum has budgeting and spend insights, but it is not the reason to choose it. Plum earns its place by saving without you thinking about it. If you have always meant to put money aside and never managed it, the auto-save algorithm and round-ups do the discipline for you. Just be aware Plum is moving real money out of your current account, so you need to keep an eye on it if your balance runs tight near payday.

Which one should you pick

Choose Emma if you want to see everything in one place and you like detail. It suits people who already have a few accounts and want a clear, categorised picture of their whole financial life, plus a tool for hunting down forgotten subscriptions. The catch is the two-account free limit, so budget for a paid tier if you have several accounts.

Choose Snoop if your goal is to spend less without much effort, especially on bills and subscriptions. The free tier is the most generous of the three for everyday users, and the switching prompts can pay for themselves. It is the best set-and-forget option, and being backed by a regulated bank may reassure people nervous about linking accounts to a small app.

Choose Plum if you struggle to save and want it done for you. The round-ups and automatic deposits build a balance in the background, and the Cash ISA and investing options give you somewhere for that money to grow. It is the only one of the three that actively moves and holds your money rather than just reporting on it.

Plenty of people run two of these together: Plum to save automatically, and Emma or Snoop to watch the spending. None of them charges to start, so the low-risk move is to install the free versions, link one account to each, and see which one you actually open after two weeks.

Whichever you choose, check that the app is FCA registered before you connect your bank. You can confirm any firm’s status yourself on the FCA Financial Services Register. For the basics of how account linking keeps your login details private, the Open Banking website is a good plain-English starting point.

Frequently asked questions

Is Emma, Snoop or Plum free? All three have a free version. Snoop’s free tier is the most complete for everyday use. Emma’s free plan limits you to two linked accounts. Plum is free to use for saving, though investing and the higher savings rates sit on paid tiers from £3.99 a month.

Are these apps safe to link to my bank? They use Open Banking, which means you log in through your own bank and never hand over your banking password to the app. Emma’s connection is read-only for tracking, so it can see transactions but not spend your money, while Plum moves money only into its own savings products with your permission. All three firms are registered with the FCA, which you can verify on the FCA register.

Can Plum lose my money? Plum’s automatic saving moves cash from your current account into a Plum savings pot, so it is still your money. Cash held in its savings and ISA products is covered by the Financial Services Compensation Scheme through the bank holding it. Money you invest in funds or stocks through Plum can fall as well as rise, so treat the investing tiers differently from the cash savings.

Which app is best for cutting bills and subscriptions? Snoop is built for this. It flags rising direct debits, free trials about to charge you, and cheaper energy, broadband and insurance deals based on your actual spending. Emma is also strong at surfacing forgotten subscriptions in its dedicated subscriptions view, but it focuses on showing them rather than switching them.

Do I need to pay for a subscription to get value? No. For most people the free tiers cover the core job: tracking with Emma, bill-cutting with Snoop, automatic saving with Plum. Pay only when you hit a real limit, such as needing to link more than two accounts on Emma or wanting custom budgets on Snoop Plus.

Can I use more than one of these together? Yes, and many people do. A common setup is Plum for automatic saving plus Emma or Snoop to keep an eye on spending. Because the free versions cost nothing, there is no harm in running two for a couple of weeks and keeping whichever you open more often.
