Going out for dinner, taking a rural getaway, or planning a vacation with friends sounds great… until it's time to settle the accounts. Calculating by hand who owes how much and who is responsible can become a huge mess , especially if there are many payments, several people involved, and different payment methods (card, Bizum, cash, etc.).
Luckily, nowadays there are plenty of iPhone apps that do the work for you. The best apps for splitting expenses with friends on iPhone let you record payments, divide them fairly, and keep track of debts , without arguments or headaches. Let's take a detailed look at the options available and when each one is best suited for you.
What do expense-sharing apps actually do?
The idea behind all these apps is very similar: you record who paid for what, how much, and for whom, and the app takes care of balancing the group's accounts . It doesn't matter if it's a trip, a shared apartment, or a couple of dinners in a row with the same friends.
Instead of relying on memory, loose notes, or crumpled receipts, expense splitting apps create a clear record of all transactions . When you decide to "close out" the trip or the month, the app will automatically show you who owes money, to whom, and how much.
It doesn't make much sense to use them for something as simple as splitting a single restaurant bill equally, but when there are several payments spread over time, different amounts, and more than two people, they become almost essential to avoid making mistakes.
In addition, many include quite useful extras: handling of multiple currencies, statistics, payment reminders, export to Excel or PDF, and even integration with payment platforms so you can settle debts instantly, as well as personal finance management tools.
Splitwise: the classic all-rounder for groups, couples and apartments
Splitwise is one of the oldest and most well-known tools. It works wonderfully on iPhone for managing shared travel expenses, whether for couples or roommates , and also has a web version so you can review or edit your accounts from your browser.
The process is simple: you create a group (trip, apartment, family, whatever you want) and add expenses, indicating who paid and how they're split . The app calculates each person's balance in real time, so you always know who's paying ahead and who owes the most.
In its free version, Splitwise includes all the basics: group creation, expense tracking, equal or customized splitting, and payment reminders so no one forgets. It also keeps a complete history so you can review any transaction whenever you want.
Where it truly shines is in its advanced features, available with its paid plan: a built-in currency converter, a receipt scanner so you don't have to enter everything manually, charts, expense search, and the ability to attach images or PDFs . It's especially useful if you travel abroad and use multiple currencies.
There's an important distinction: Splitwise doesn't move money itself in all regions; instead, it focuses on calculations and keeping balances clear . In some countries, it can be linked to compatible payment services, but generally, the logic is to calculate, not to pay directly.
Tricount: simple, highly visual, and completely free
Tricount is another top choice for trips and plans with friends. Its philosophy is to simplify the complex without overwhelming you with too many options , and it certainly succeeds.
When you create a "tricount," you add the group members (by invitation or link) and record each expense with its payer and beneficiaries . The app displays a detailed list of expenses on one side and a section called "Who owes whom how much?" on the other, which summarizes exactly the payments that would need to be made to bring the balance to zero.
One of its strengths is that it doesn't have a premium version: everything it offers is included at no extra cost . This means you can add as many expenses as you want, with no daily limit and no intrusive advertising, which is a welcome feature compared to other services.
Among the integrated features are a currency converter, an offline mode to continue recording expenses even without data, monthly statistics, photo uploads, and online backups . Furthermore, if you already used Splitwise, you can import your data to Tricount so you don't have to start from scratch.
Another very convenient detail is that not all participants are required to download the app ; you can keep control yourself and share the link or the final summary with the rest of the group, ideal if there is someone who doesn't want to install anything on their iPhone.
Settle Up: thoughtful design and great flexibility
Settle Up is also available on iPhone and is especially useful when managing large groups or situations with more complex splits. Its "bubble" interface shows each person's balance at a glance , making it very clear who is in the black and who is in the red.
With this app, you can split expenses equally, by percentage, or with custom amounts per person , which is very useful for situations like someone having more drinks or children paying less. The timeline at the bottom shows all the transactions and steps necessary to settle accounts between participants.
If you prefer, you can manage the app yourself without inviting others, or share a link so your friends can join the group and contribute by adding expenses . This flexibility means there's no "obligation" for everyone to have an account, but it does allow each person to see their balance in real time.
Settle Up has a very functional free version, and a paid plan with extras designed for those who use it daily: ad removal, scheduling of recurring or future payments, payment reminders, expense categories, and exporting data to Excel.
It also supports multiple currencies, so it's a good candidate for international travel or for groups with members in different countries who pay in different currencies.
Splid: Maximum speed and offline use
Splid has earned a reputation as one of the fastest apps for setting up simple accounts. Its interface focuses on the essentials: recording expenses, seeing who owes what, and generating a clear summary in seconds . Perfect when you want to budget for a short trip or a few meals together.
You can use Splid completely offline, creating local groups on your iPhone to enter expenses and check the balance without needing the internet . If you then want others to participate, you can sync the group online and allow your friends to add their own payments.
One of its biggest advantages is that it doesn't require mandatory registration to start using it , which encourages users to try it out immediately without forms or accounts. It also supports over 150 currencies, with the ability to convert them to a single currency when calculating who owes how much.
Their business model is simple: the app is free to manage one group, and with a one-time payment you can unlock the creation of multiple groups and the export of data to Excel . No monthly subscriptions, it's all one-stop shop.
Another highly valued feature is the generation of summaries ready to print or share in PDF , ideal for keeping track of expenses at the end of a trip and sending the breakdown to everyone transparently.
Finsplit, Group Xpense, Sesterce, Splittr and more options for iPhone
Besides the classic apps, the App Store offers other iPhone-focused apps that might be a better fit for your usage style. These include Finsplit, Group Xpense, Sesterce, Splittr, and the "Spending Expenses" app, among others , all designed to make splitting bills a breeze.
With Finsplit , you can create specific groups for each plan (trip, dinner, apartment, event, etc.) and add expenses by indicating the amount, a short description, and the people involved . Then you can choose whether to split everything equally or set custom proportions when someone pays more or less.
Group Xpense is designed for detailed expense tracking. It allows you to manage expenses from both the iPhone app and the web, track them in real time, and work offline if you run out of data. One of its advantages is its focus on clear records, making it ideal for organized groups.
The Sesterce app is perfect for shared apartments, families, or groups of friends who frequently make plans together. It lets you quickly record expenses, split them fairly, and, if needed, simulate transfers between two people to see how the balance would be . It also allows you to customize categories and export your history as a CSV file for later review.
Splittr is very popular among travelers because it works without registration, accepts any currency, and allows you to categorize expenses and export them as PDFs or CSV files . It even offers statistics and interesting tidbits about the group, adding a fun touch. Its algorithm attempts to minimize the number of payments required when it's time to settle accounts.
Finally, the "Spending Split" app for iPhone focuses on the essentials: noting who paid for what, how much each person is responsible for, and, if you want, simulating money transfers between participants . It's a good option if you're looking for something very specific for splitting group expenses without too much fuss.
Apps that track expenses vs. apps that also pay
PQEBDXGKQXXGODBF442TIVXZG4
A key point to understand is that not all expense-sharing apps allow you to send money . Many simply calculate expenses and display balances, while others directly integrate payments between users.
The first group includes tools like Splitwise, Tricount, Settle Up, Splid, Finsplit, and Splittr . Their purpose is to record, split, and show who owes what, but they aren't always connected to your bank or e-wallet . You see the balance and then decide whether to pay with Bizum, bank transfer, cash, etc.
The second group includes options like PayPal or Revolut , which, in addition to helping you split expenses, incorporate money transfers within the app itself. These apps not only calculate costs but also allow you to settle the debt in just a couple of taps.
In many cases, the most practical thing is to combine a calculation app with a payment app : for example, you organize the trip with Splitwise or Tricount and then each person pays their share by Bizum, PayPal or Revolut following the amounts indicated by the expense application.
PayPal: split bills and pay instantly
PayPal, well-known for online payments, also includes a feature for splitting expenses. From the app, you can create shared invoices, divide them among several people, and automatically send payment requests so that everyone receives a notification of their share.
The system calculates each participant's proportional share and allows you to see at any time which amounts are outstanding and which have already been paid . Since payment is made through PayPal, you don't have to switch between apps, which greatly speeds things up.
It's a particularly convenient solution for small groups or one-off situations where everyone has a PayPal account . However, as a tool for keeping a very detailed record of expenses or making complex splits, it falls short of specialized applications.
Revolut: Shared expenses integrated into your digital bank
Revolut, in addition to being a digital banking app, includes a built-in feature for splitting payments directly after making a purchase with your card . As soon as you pay, you can specify who you want to share the expense with and automatically calculate the corresponding amounts.
The app provides an overview of shared expenses for each group, showing who owes money and how much , and allows for instant refunds between Revolut users. Everything is managed within the same platform, without the need for additional apps.
It's especially practical if everyone in the group uses Revolut daily for payments, savings, or travel . In that case, reviewing the expenses of a trip, a shared apartment, or several dinners becomes almost automatic, because payments and splitting are fully integrated.
Banking options and personal finance management apps
Some banks have also jumped on the bandwagon of shared expenses. For example, the BBVA app includes a specific tool for creating spending groups and splitting both one-off and recurring expenses , available even to people who are not bank customers.
Within this feature, you can invite participants, record payments for rent, travel, or activities, and indicate how they were paid (cash, bank transfer, Bizum) . This way, the entire "who paid what" process is managed from the same banking app you use every day.
Alongside these functions, BBVA offers other financial management tools such as BBVA Invest for investment advice, BBVA Valora for finding housing, or a vehicle comparison tool that shows the savings between electric and combustion engine cars, demonstrating the extent to which banking apps are becoming multifunctional.
On the other hand, there are apps that aren't so much for splitting expenses with friends as they are for managing your personal finances and helping you save . Tools like Fintonic, Plum, Emma, ​​and Monefy fit in here, and they can be excellent complements to dedicated expense-sharing apps.
Fintonic , for example, lets you connect your accounts, cards, and insurance policies to provide a comprehensive analysis of your spending, suggest financial products, and even advise you on choosing loans . It operates in countries like Spain, Mexico, and Chile and has hundreds of thousands of linked bank accounts.
Plum uses artificial intelligence to detect your savings capacity and automatically transfer small amounts to a piggy bank or simple investment products . It's ideal if you struggle to save on your own and need the app to do it for you without much thought.
With Emma, ​​you can take your analysis a step further: she helps you identify active subscriptions you may no longer use, hidden bank fees, and spending patterns that can be improved . Her goal is to act as a financial assistant, revealing where your money is going without you even realizing it.
Monefy , on the other hand, focuses on simplicity: it lets you manually record income and expenses, without needing to link bank accounts , and displays clear charts by category so you can see where a large part of your budget goes each month.
Advantages of using apps to split expenses
Beyond convenience, expense-sharing apps bring transparency and greatly reduce awkward situations when money is involved between friends or family.
On the one hand, everyone in the group can see the recorded expenses and how they were divided at any time . The classic "I paid more" or "you didn't write that down" disappears, because everything is recorded with the date, amount, and payer.
Forgetfulness is also reduced: if you get into the habit of spending 30 seconds after each payment to enter it into the app, the record is always kept up to date and you don't have to try to reconstruct the trip account a week later by relying on memory.
If you're traveling abroad, the multi-currency support and built-in converters prevent errors when switching between currencies . Just make sure all your entries are in the correct currencies to avoid any surprises.
Finally, the ability to export the data (PDF, Excel, CSV) and generate detailed summaries allows anyone to calmly review the accounts . This gives the group a lot of confidence and helps everyone feel that the distribution has been fair.
Common mistakes and tips to avoid them
Even with the best apps, if they aren't used with some discipline, they can have the opposite effect of what you're trying to achieve . There are several common mistakes that should be avoided from the start.
One of the most common mistakes is not writing down expenses at the time and hoping you'll remember later . Eventually, cash payments are forgotten, small purchases are missed, or amounts are confused, and that's when the doubts begin.
It also often happens that someone pays another person outside the app (via Bizum, for example) and no one registers that payment as "paid ." The app will continue to show a debt that has actually already been paid, which distorts the true balance.
Another mistake is mixing strictly personal expenses with shared expenses . Ideally, you should clearly separate what belongs to the group and what doesn't, and if necessary, create separate groups for travel, housing, leisure activities, etc.
The best solution is to agree on some basic rules: who will be responsible for creating the group, when each expense is recorded, when the accounts are closed, and how final payments will be made . With four clear rules, everything runs much more smoothly.
Privacy and security: what you should keep in mind
It's normal to worry about security when it comes to apps that manage money. Most well-known apps use standard encryption and good security practices , but it's still worth reviewing a few points.
Many of these apps, like Splitwise, Tricount, or Splid, don't require you to link your bank accounts ; you simply enter expenses manually. In these cases, the risk is limited to the transaction details, not your money directly.
Others, like PayPal or Revolut, do handle real payments and more sensitive financial data . In these cases, it's important to enable two-step verification, use strong passwords, and always download apps from the official App Store.
Before choosing one, check what permissions it requests, what data it collects, and whether it offers the option to operate manually without linking accounts . If privacy is a major concern, an app that only tracks expenses may be more than sufficient.
With all these options on the table, choosing the best app for sharing expenses on iPhone will depend on the type of use you're going to give it, the level of detail you need, and whether you want the app itself to manage the payments or prefer to continue using your bank, Bizum, or PayPal to send the money.
