Overview

Splitwise organizes shared costs so participants can see who owes whom. Expenses can be divided equally or unequally, including by percentage or shares; balances are totaled, and debts can be simplified across a group. That makes it practical for recurring household costs as well as trip spending, where repeated one-off calculations otherwise create friction.

Entries remain informal records, not legally binding obligations. Splitwise is therefore useful for coordination and bookkeeping among people who trust one another, but it should not be treated as a substitute for contracts or formal accounts. Expenses are private by default and visible to the friends or group members they are shared with.

Key features

Flexible splitting: Equal splits cover straightforward shared bills; percentage and share-based splits give groups a way to allocate costs unevenly.
Balance simplification: Group totals and debt simplification reduce the number of repayments members need to settle between themselves.
Offline access and cloud sync: Users can work offline and sync through the cloud, a helpful combination for groups recording costs while traveling.
Payments and records: Users can record cash or online payments. Splitwise Pay adds a wallet for sending money to friends, but it is US-only; international transfers are not supported.
Pro import and currency tools: Pro can import recent purchases from a connected credit or debit card for splitting, and convert currencies using current foreign exchange rates. Transaction import is currently US-only, limiting its usefulness for international groups.
Third-party API: Other applications can access a user's account data with that user's authorization. This is the clearest fit for builders seeking an integration point, though the API does not make shared entries formal records.
Privacy and security: Shared expense details are limited to invited friends or group members. Splitwise says it uses encryption techniques and authentication procedures among its technical and administrative protections.

Splitwise supports more than 100 currencies, but that breadth should not be confused with universal payment availability: Splitwise Pay is limited to the US, and international transfers are not supported. Email support aims to answer most requests within one business day.

Pricing

Splitwise is freemium. The Free plan costs 0.00 USD per free and includes shared expenses and balances, groups and friends, equal or unequal splits, recurring expenses, offline mode, cloud sync and unlimited expenses. That is a substantial baseline for a household or occasional trip group, with no stated expense cap to force an upgrade.

Splitwise Pro has custom pricing and includes unlimited expenses, US-only transaction import, currency conversion, charts and graphs, receipt scanning and itemization, expense search, default split settings and no ads. It is the better fit for people who regularly manage many entries or want faster capture and analysis; the free plan gives up those Pro tools, not expense capacity.

Other named options are Individual + Trip Pass, which includes all Splitwise Pro features and one annual Trip Pass; Duo + Trip Pass, for two people; and Monthly subscription, with all Splitwise Pro features. Each has custom pricing. The available plan terms do not state a trial length, renewal schedule or usage quotas beyond the Free plan's unlimited expenses, so those should not be assumed.

Platforms

Splitwise is available on Android, iOS and the web, and provides an API for authorized access to user account data. That combination supports both direct use by groups and integrations built around their expense records.

Who it's for

Choose Splitwise for friends, families, housemates and trip groups that need a shared ledger, flexible allocations and a clear balance after multiple expenses. It also merits consideration by builders who need an API to connect authorized account data to other applications.

Look elsewhere if the requirement is legally binding debt documentation, international transfers, or US-style card import outside the United States. The service is not for children under 13.

Pros and cons

Pro — Flexible allocation: Equal, percentage and share-based splits accommodate both simple bills and uneven contributions.
Pro — Free plan has no expense cap: Groups can keep recurring records and sync across offline use without paying for unlimited expense volume.
Pro — Useful integration path: The API allows other applications to access account data with user authorization.
Con — Not a payment rail for every group: Splitwise Pay is US-only, and international transfers are not supported.
Con — Key Pro tools have a geographic limit: Transaction import is US-only, reducing its value for users elsewhere.
Con — Informal records only: Balances and payment entries are not legally binding, so Splitwise cannot serve as formal debt documentation.

Verdict

Its API is a meaningful advantage for builders integrating authorized account data. Choose another tool when international transfers, non-US transaction import or legally binding records are essential.
