Splitwise

Splitwise is a web and mobile app built by a Providence, Rhode Island company to track shared expenses and settle debts between friends and family. The core app is free on iPhone, Android, and the web, while Splitwise Pro adds premium features for power users. If you've ever had to text someone asking "do you remember how much I paid for your half of dinner?", this is the tool built directly for that problem.

The app stores shared expenses in the cloud so your balance information stays accessible on any device. Everyone invited to a group can log in and see exactly who owes what to whom, with automatic calculation of net balances. Because it's a ledger between people rather than a bank-synced tracker, the setup is straightforward: you enter expenses manually as they happen, categorize them, and specify who participated and what split (equal, by percentage, by shares, or custom amounts).

Splitwise is built for organizing shared costs across multiple scenarios. You can create separate groups for your household, a vacation trip, a friend group, or any collection of people sharing money. Each group maintains its own ledger, so your ski trip expenses don't mix with your housemate tallies. Within a group, you can set different split percentages for different people, so if one person isn't splitting rent but is splitting groceries, you just create separate expense entries with their actual participation.

Adding an expense is designed to be quick. When someone covers a group cost, they open the app, type in the amount, select the group, pick the participants, confirm the split, and it's recorded. The app supports 100 or more currencies, so if you're traveling internationally or have friends abroad, you can record expenses in their local money and settle up in yours. The free tier lets you add as many expenses as you want without daily limits.

One friction point with expense-splitting apps is that someone always has to front the full cost. With Splitwise, there's no avoiding that first step, but the ledger makes settling afterwards automatic. Once the app calculates everyone's net balance, you can record cash payments, Venmo transfers, or other payment methods directly in the app to mark debts as settled. The app calls this "pay friends back" and it closes out the shared expense cycle. The interface is designed for quick entry: opening the app from your home screen, tapping the add button, and recording the expense takes seconds. For recurring scenarios like household bills or regular group lunches, recurring expense automation saves you from retyping the same split every single time, so if rent is always split three ways or your weekly grocery cost follows an uneven split, the app remembers and applies it automatically.

The free app handles the core job well, but Splitwise Pro addresses pain points that appear only after heavy use. Receipt scanning lets you photograph a restaurant bill or invoice and the app parses the items and amounts automatically, then assigns them to participants. After scanning, you can itemize: if you grabbed lunch for three people, you assign each person their actual order rather than splitting the total evenly, which matters when someone gets the expensive entrée. This accuracy stacks up across dozens of shared meals.

Charts and graphs in Pro give you spending trends by category and time, showing patterns you'd miss from a list of transactions. If you're planning a big trip and want to watch the daily run, or tracking whether shared household spending is truly balanced, visual breakdown helps. The app also includes expense search in Pro so you can locate an old charge if you need to edit or verify it. Because the free version allows unlimited expenses with no daily caps, you're not throttled if you have a high-spending day or a trip where every meal and activity gets logged. The cloud sync ensures that expenses you log on your phone immediately appear on any other device, so your partner or roommate sees the updated balance within seconds without needing to refresh.

Currency conversion in Pro works for multi-currency groups. If you have shared expenses in US dollars and euros, Pro converts them all to a single currency for balance calculation and settlement. Transaction import (available only for residents of the US) connects a credit or debit card and pulls recent purchases into the app, letting you pick which ones to split rather than typing each one by hand.

For recurring shared expenses, the app includes a recurring expense feature that automatically creates the same split on a schedule. For long-term groups like housemates sharing rent or utilities, this saves retyping the same expense each month. Groups can be organized by category, so you might have one for household costs, one for a vacation trip, one for wedding expenses, and one for friends' dinners. Within each group, balances are tracked independently. If you owe your partner money for shared household bills and they separately owe you money for a group trip, Splitwise shows both debts independently per group, letting you settle them individually or negotiate combinations.

The free app is supported by ads, while Pro removes advertisements for a completely clean experience. Pro also includes early access to new features, so paying members see improvements to the interface or functionality before the free tier. The app emphasizes fairness mediation, with separate "fairness calculators" available through the site to help friends or roommates reach agreement on how to split costs in tricky situations. These calculators aggregate crowdsourced data from the Splitwise user base to suggest fair splits in common scenarios, so if you're uncertain whether a cost should be split evenly or unevenly, the calculator offers a neutral reference point based on what other users in similar situations have chosen.

Splitwise works for offline mode on mobile, meaning you can add expenses without a data connection and they sync once you're back online. The app maintains sync across your phone, tablet, and web browser so your balance is always current no matter where you access it. The company also offers a separate Splitwise Pay service for settling balances directly through the app and a Splitwise Card product, expanding beyond tracking into actual payment settlement for users who want integrated handling of both the ledger and the money transfer.

The free tier supports up to 7 languages and works in 100 plus currencies, so the app is genuinely international. If you're a couple merging finances, roommates splitting rent, parents coordinating kids' activity costs, friends planning a trip, or any group managing shared money, the free core covers your need. The experience is genuinely free with no sneaky paywall: you can add unlimited expenses, track unlimited groups, and settle balances without paying anything.

Pro pricing isn't disclosed on the site's public pages, so you'll need to tap into the app to see the cost. The app does offer a free trial of Pro features before any charge, so you can evaluate whether receipt scanning and charts matter to your workflow before committing. For people handling just a few shared meals or one joint account, the free tier covers it. For those managing household finances with partners or organizing frequent group trips, the convenience features in Pro often pay for themselves in time saved.
