The best money-saving apps in the UK are the ones that fix your biggest leak. For most people that means one budgeting app to see where money goes, one cashback app for things you already buy, your supermarket's loyalty app, and one app that helps you actually save the difference. Food waste apps such as Too Good To Go and Olio are a good extra if you eat out or shop for food often.
You do not need a phone full of apps. Each one takes attention, and some charge subscriptions that can cancel out what they save. Three or four well-chosen apps, used consistently, will do more than ten you forget about.
This guide covers the six main types of money-saving app, how we chose them and how to build a small set that works for you. If cashback is your main interest, our dedicated cashback apps guide goes into much more depth.
How we chose
We do not use affiliate links and no app paid to be included. We only name apps we could confirm are available in the UK in October 2026, and we judged each type on:
- Real savings: does it reduce what you spend or increase what you keep, not just show you nice charts?
- Cost: is the free version useful, and is any subscription clearly worth more than it costs?
- Effort: how much time it takes each week to get the benefit.
- Safety: apps that connect to your bank use Open Banking and should be authorised or registered with the FCA, which you can check on the FCA register. Money held in non-bank apps may not be FSCS protected.
- Overlap: whether it does something your banking app already does for free.
The six types of money-saving app compared
Different apps save money in different ways. This table shows where each type fits.
| Type | How it saves you money | Examples |
|---|---|---|
| Budgeting | Shows where your money goes so you can cut back | Emma, your bank's own app |
| Cashback | Pays a share back on purchases you already make | TopCashback, Quidco, Airtime |
| Grocery receipt | Money back on featured products | Shopmium, CheckoutSmart |
| Supermarket loyalty | Member prices and points at one chain | Tesco Clubcard, Nectar |
| Food waste | Cheap or free surplus food | Too Good To Go, Olio |
| Saving and challenges | Helps you set money aside regularly | Round-up apps, SYM |
Budgeting apps: see where your money goes
A budgeting app is the best place to start because it shows what to cut. Most UK budgeting apps use Open Banking to pull in transactions from your accounts and sort them into categories, so you can spot subscriptions you forgot about or a takeaway habit that has crept up.
Emma is one of the best known. It has a free version and paid tiers, and some features such as subscription tracking and payday budgeting are in the paid plans at the time of writing (October 2026). Before paying for any budgeting app, check whether your bank's own app already offers spending categories and saving pots for free, as many now do.
If you would rather not connect your bank, a simple plan works too. Our budget planner lets you set out income and spending by category in a few minutes. For a fuller comparison, see our guide to the best budgeting apps in the UK.
Cashback and grocery apps: money back on what you buy
Cashback apps pay you a share of what you spend at certain retailers. The main kinds are cashback sites such as TopCashback and Quidco for online shopping and switching deals, card-linked apps such as Airtime that earn automatically when you pay with a linked card, and receipt apps such as Shopmium and CheckoutSmart that pay back part of the price of featured grocery products.
They work best for spending you were going to do anyway. Always compare the total price first, because a deal with cashback can still cost more than one without. Withdraw your balance regularly, as money held in a cashback account is not FSCS protected.
We cover how each type works, fees, payout times and catches in our full cashback apps guide. If you are thinking of a cashback credit card as well, read our cashback credit cards comparison first, as they only make sense if you pay in full every month.
Supermarket and food waste apps: cut the food bill
Food is one of the easiest places to save with an app.
- Supermarket loyalty apps: Tesco Clubcard and Nectar (used at Sainsbury's and other retailers) offer member prices and points. If you shop at one chain most weeks, the app is worth having so you get the member price at the till. Just be wary of being steered away from cheaper shops by points.
- Too Good To Go: buy surprise bags of surplus food from cafés, bakeries and shops near you at a reduced price. You cannot choose exactly what is in the bag, so it suits people who are flexible.
- Olio: a free app for sharing unwanted food and household items with neighbours. You request listed items and collect them. Read our Olio guide for how it works.
Saving apps: make sure the savings actually stick
This is the step many people miss. Cutting £20 off the food shop or earning £15 cashback only helps if that money ends up somewhere other than your current account. Otherwise it quietly disappears into everyday spending.
There are two main approaches. Round-up and automatic saving apps move small amounts for you, which is low effort. Our guide to round-up savings apps compares how they work, and you should check whether the account behind them is FSCS protected.
The other approach is a savings challenge, where you choose to set aside a set amount each day or week. SYM is a free savings challenge app for iPhone and Android. It tells you how much to put aside today and you tap to log it. It does not connect to your bank or hold your money, so you stay in control. A simple habit is to log every cashback payout or food shop saving as part of your challenge. You can plan a target with the savings goal calculator or try the 52-week challenge calculator.
How to build a set of apps that works
Start small and add only what earns its place:
- Week 1: use a budgeting app or the budget planner to find your two or three biggest spending categories.
- Week 2: add the app that tackles your biggest category: a supermarket loyalty or food waste app for food, a cashback site for online shopping and bills.
- Week 3: set up somewhere for the savings to go, such as a savings challenge in SYM or an automatic transfer to a savings account.
- Every few months: delete apps you have not used and cancel any subscription that has not paid for itself.
- If you have debt: put savings towards the most expensive debt first. The debt payoff calculator and credit card payoff calculator show how much extra payments save in interest.
Common mistakes with money-saving apps
- Paying for several app subscriptions that each save less than they cost.
- Buying things because an app offers cashback or points, rather than because you need them.
- Leaving money in app balances instead of withdrawing it to your bank or savings.
- Connecting your bank to apps you do not recognise. Check the FCA register before giving any app access to your accounts.
- Using buy now, pay later in shopping apps without a plan to repay, as it is still borrowing.
