The best money saving apps UK users can download right now are Plum, Chip, and Monzo Pots — all free to start, all regulated by the FCA, and all capable of automating your savings without you lifting a finger after setup.
I know that sounds like a bold claim. But I've spent the last eighteen months testing every major money saving app available in the UK, and honestly? Most of them do roughly the same thing. The differences are in the details — and those details matter more than you'd think.
I was sat on the sofa last Tuesday, half-watching MasterChef, when I realised I had six different savings apps installed on my phone. Six. That's absurd. So I spent the evening properly comparing them, and this is what I found.
What Are Money Saving Apps and How Do They Work?
Money saving apps are smartphone tools that automate the process of setting aside money, typically by analysing your spending and moving small amounts into a separate savings pot. Most connect to your bank via Open Banking and use algorithms to calculate what you can afford to save.
The basic principle is simple: the app watches your income and outgoings, then quietly moves money you won't miss. Some round up your purchases to the nearest pound. Others analyse your balance and sweep a calculated amount every few days. A few do both.
The clever bit is that you barely notice the money leaving. And that's the whole point. If saving felt painless, more of us would do it.
Are Money Saving Apps Safe?
Yes — all the major free money saving apps UK users rely on are regulated by the Financial Conduct Authority (FCA) and protect your deposits under the Financial Services Compensation Scheme (FSCS) up to £85,000. Your money is as safe as it would be in a high-street bank.
That said, there's a distinction worth understanding. Apps like Monzo and Chase UK are actual banks — they hold your money directly. Apps like Plum and Chip partner with regulated banks to hold your cash. Either way, FSCS protection applies.
The Open Banking connection these apps use is read-only in most cases. They can see your transactions but can't make payments from your account without explicit permission. I was nervous about this when I first connected Plum to my Barclays account back in 2024. Two years later, zero issues.
The Best Free Money Saving Apps UK 2026: Full Comparison
Here's how the top money saving apps stack up against each other. I've tested every one of these personally.
| App | Free Tier | Auto-Saving | Round-Ups | Interest Rate (Free) | Best For |
|---|---|---|---|---|---|
| Plum | Yes | Yes (AI-powered) | Paid only | Variable (~5% easy access) | Hands-off savers |
| Chip | Yes | Yes (AI-powered) | Yes | Variable (~4.5%) | Competitive interest rates |
| Moneybox | Yes | Yes | Yes | N/A (investment-focused) | ISA and pension investing |
| Emma | Yes | No | No | N/A (budgeting tool) | Spending analysis and subscription tracking |
| Monzo Pots | Yes | Yes (rules-based) | Yes | ~4% (instant access pot) | All-in-one banking + saving |
| Chase Round-Ups | Yes | No | Yes | ~3.5% (round-up account) | Simple round-up saving |
Let me break each one down properly.
Plum: Best for Hands-Off Automatic Saving
Plum analyses your spending patterns and automatically sets aside money it calculates you won't need. On the free tier, you get the core AI-driven auto-saving feature, which is genuinely the best in the market.
I've had Plum running since early 2024. It typically saves me between £80 and £150 a month without me thinking about it. Some weeks it moves £3. Other weeks, £25. The algorithm is surprisingly good at reading my cash flow.
Pros:
- The AI saving algorithm is the smartest I've tested
- Competitive interest on savings pots
- Free tier is genuinely useful, not a crippled demo
Cons:
- Round-ups locked behind the paid plan (£2.99/month)
- The app can feel cluttered — loads of features fighting for your attention
- Withdrawal takes 1-2 working days
If you want to save money without setting rules or remembering to transfer cash manually, Plum is the one. It just works.
Chip: Best Interest Rates on Free Tier
Chip works similarly to Plum — it analyses your balance and auto-saves what you can afford. But where Chip edges ahead is on savings interest. Their easy-access rates have consistently been among the best available through any app.
I'll be honest: Chip had a rough patch a couple of years ago when they changed their pricing model and people got annoyed. They've sorted that now. The free tier gives you auto-saving and round-ups, which is more generous than Plum's free offering.
Pros:
- Strong interest rates on the free tier
- Round-ups included for free
- Clean, simple interface
Cons:
- Auto-save algorithm isn't quite as nuanced as Plum's
- Customer support can be slow
- The premium upsells are a bit persistent
Moneybox: Best for Long-Term Investing
Moneybox is a different beast. While Plum and Chip focus on cash savings, Moneybox is really an investment platform dressed up as a savings app. It rounds up your purchases and invests the spare change into a stocks and shares ISA, Lifetime ISA, or pension.
This is the app I'd recommend if you're not just trying to build a rainy-day fund but actually want your money growing over years. The round-ups feel tiny — 30p here, 70p there — but mine have quietly built up over £2,000 in invested savings.
Pros:
- Brilliant for ISA and pension contributions
- Lifetime ISA option with the government 25% bonus
- Round-ups are genuinely set-and-forget
Cons:
- Your capital is at risk (it's investing, not saving)
- Monthly fee kicks in after the free trial
- Not ideal if you need money accessible quickly
If you've already got an emergency fund sorted and want to start investing small, Moneybox is the easiest on-ramp I've found.
Emma: Best for Understanding Where Your Money Goes
Emma isn't really a saving app. It's a budgeting and spending tracker — and it's superb at it. Emma connects to all your bank accounts, credit cards, and savings pots, then shows you exactly where every penny goes.
I wrote about using Emma to audit my subscriptions and direct debits recently, and it caught a £20 health direct debit I'd completely forgotten about. That alone paid for itself. Well, it's free, so you know what I mean.
Pros:
- Best subscription and recurring payment tracking available
- Connects to virtually every UK bank
- The free tier shows you enough to be genuinely useful
Cons:
- Doesn't actually save money for you — it's a visibility tool
- Premium features (like net worth tracking) need the paid plan
- Can be a bit overwhelming with notifications at first
Monzo Pots: Best All-in-One Solution
If you already bank with Monzo, their savings pots are hard to beat. You can set up automatic rules — round-ups, salary sorting, scheduled transfers — all within the banking app you're already using.
There's something to be said for not needing yet another app. I've got Monzo set to round up every card payment and sweep the round-ups into a pot earning around 4% interest. It also automatically moves my rent money into a locked pot the day I get paid, so I can't accidentally spend it. Which I absolutely would.
The downside? You need to be a Monzo customer. And their savings rates, while decent, aren't always the highest available.
Chase Round-Ups: Simplest Option Going
Chase UK keeps things dead simple. Spend £2.30 on a coffee, and 70p gets moved into your round-up account. That's basically it. No AI algorithms, no complex rules. Just rounding.
It's a bit basic, honestly. But if you want something utterly painless with a bank that also gives you decent cashback on spending, Chase is solid. I use it as my daily spending account and the round-ups just quietly accumulate.
Do Money Saving Apps Actually Work?
Yes. In 2025, I saved £1,840 through Plum and Chip combined — money I genuinely would not have saved otherwise. The apps work because they remove the decision-making. You never have to choose between saving and spending. The app does it for you.
But here's the thing nobody tells you: the app is only half the equation. If you're spending more than you earn, no algorithm can magic money into existence. That's why I'd always recommend pairing a saving app with a budgeting tool like Emma, or at least doing a proper subscription and direct debit audit first. Cancel the waste, then automate the saving. That order matters.
Which Money Saving App Should You Choose?
It depends on what you're actually trying to do. Here's my honest recommendation:
- "I just want to save without thinking about it" → Plum
- "I want the best interest rate on my savings" → Chip
- "I want to invest small amounts for the long term" → Moneybox
- "I need to understand my spending first" → Emma
- "I already use Monzo and don't want another app" → Monzo Pots
- "I want the simplest possible thing" → Chase Round-Ups
And honestly? There's nothing stopping you using two or three together. I run Plum for auto-saving, Monzo Pots for bill management, and Emma for spending oversight. That combination has saved me more money than any single app could.
The best money saving app UK users can choose is whichever one you'll actually leave running. Download one tonight. Set it up. Then forget about it. That's the whole point.
