Plum is an AI-powered money management app that helps you save, invest, and manage your money automatically.
The app analyses your spending and automatically sets aside money you won't miss. With features like round-ups, savings rules, and easy access savings accounts, Plum makes building your savings easy.
Plum is a savings app that everyone should be given at school - instead I invested my pocket money on fizzy cola bottles whilst my parents kindly covered the mounting dental bills.
You'll get £10 free cash via TopCashback when you sign up to Plum and connect your bank account. There is a small deposit required via direct debit (mine was just £5.15), but you can withdraw it straight back once your cashback arrives. No transactions required beyond that - just link your bank and the cashback is yours.
If you decide to try Plum after getting your £10 free cash, the automatic savings feature is genuinely useful. The AI analyses your spending and you can set up rules to save amounts without you noticing. Plus you can earn 3-4% on easy access savings. Check out the full review below for more details.

I've come away thinking Plum is one of the most useful free apps you can have on your phone if you struggle to save manually. Over two million people use it, ratings are consistently strong (4.7 on iOS, 4.6 on Android), and the auto-saver genuinely moves cash into your pocket without you having to think about it. The trick it pulls off is doing the boring bit of saving so you don't have to.
The free Basic plan is generous: auto-savings, round-ups, the Cash ISA with no fees, and a starter Easy Access Pocket are all included without paying a penny. The paid tiers (Plus £3.99, Boost £7.99, and Max £14.99 a month as of May 2026) bump up the interest rate and lower the investment fees, but most casual users won't need them.
Where Plum is less compelling is if you're a confident DIY investor with a bigger pot. Once your investments grow beyond a few thousand pounds, the platform fee on the cheaper tiers starts adding up, and you'd save money moving the investment piece to a lower-cost broker. For everyone else who just wants a quiet, friendly app that nudges cash into savings each week, Plum delivers.
Saveable Limited is authorised and regulated by the Financial Conduct Authority (FRN 739214). Deposits held with Plum's partner banks via the Easy Access Pocket and Cash ISA are eligible for FSCS protection up to £120,000 per person, per bank. Investments held in a GIA, Stocks and Shares ISA, or SIPP are covered by the FSCS up to £85,000 per person. The value of investments can go down as well as up.
