What is Sesterce?
Sesterce is a shared-expense tracker for groups: friends on a trip, a couple, roommates or colleagues. You and the other members add what each person paid, and it works out who owes what so the group can settle up. It runs on Android, iOS and the web, and the page presents it as free for most features, with some advanced options in a Premium package.
What it does in practice
- Create a group for a trip, household or team, then add members — the page says members can be added without creating an account.
- Log expenses as they happen; the balance is computed automatically.
- Let everyone follow the group's expenses from their own phone or browser.
- Export expenses to a table if you want to keep a record or work on them elsewhere.
- Sort expenses by category for a quick view of where the money went.
How joining works
Each group has its own identifier and can be password-protected. Anyone with the identifier and password can join, which is convenient for a group that changes members mid-trip, though it also means the password is the main thing keeping the group private.
Trade-offs to weigh
The no-account approach is the distinctive part: it lowers the barrier for a friend who does not want another signup, but it also means access depends on the group identifier and password rather than personal logins. If you want a clear audit trail of who changed what, that is worth testing before you rely on it for a long-running shared household.
A concrete scenario
Four friends rent a house for a week. One pays for groceries, another for fuel, a third for a group dinner. Each adds the expense to the group; by the last day the app shows a balance and the group settles with one or two transfers instead of a chain of small repayments. The same setup works for a couple splitting rent and bills, or roommates tracking shared utilities.
Next step
Open the web app and create a test group with one or two expenses to see whether the balance view matches how your group thinks about splitting. If you want alternatives to compare, look at Splitwise for a widely used expense-splitting app and Tricount for a simple group-expense tool.
How do I create a group and add members on Sesterce?
Create a group in Sesterce from either the web app or the mobile app, then add people by name. The key detail from the site: members do not need their own Sesterce account to be added — you can enter them yourself and track their share. Once the group exists, Sesterce gives it a group identifier; anyone who has that identifier plus the group password can join and see the expenses.
A practical setup order:
- Open the web app or install the Android/iOS app.
- Create a new group and give it a recognisable name (for example, "Flat 12" or "Lisbon trip").
- Add each member by name. They can be added without registering.
- Set a password on the group if you want to control who can open it.
- Share the group identifier and password with anyone who should join on their own device.
- Start adding expenses; Sesterce computes each person's balance automatically.
When this approach fits
This suits couples, roommates, friend trips and colleagues who want a shared running total without asking everyone to sign up first. The no-account, no-email design is the main trade-off in your favour: less friction when adding a reluctant participant. The trade-off against it is that a password-protected group identifier is the access control — anyone you give it to can see the group, so share it the way you would a shared document link.
If you get stuck
Check the group identifier before inviting people; a wrong character is the most likely reason someone cannot join. If your group is larger or longer-running, compare the workflow with Splitwise or Tricount, which handle similar shared-expense tracking.
How do I share my Sesterce group with others?
A Sesterce group is shared by its group identifier plus the password attached to that group. Anyone who has both can open the group on the web or in the mobile app and start viewing or adding expenses — they do not need to create an account first.
The practical sequence:
- Open the group you want to share.
- Find its group identifier and its password.
- Send both to the people you want in the group.
- They join using those two pieces of information and can then track the group's expenses.
A quick example: you set up a group for a shared flat, note the identifier and password, and send them in your household chat. A new roommate opens the web app, enters both, and immediately sees the running balance and can add their own expenses.
Because access depends on the identifier and password rather than on individual accounts, treat the password as the actual key to the group. Share it only with people who should see the group's spending, and change it if it spreads further than intended. The password protection is a deliberate feature, so it is worth using rather than leaving the group open.
If someone only needs a snapshot rather than ongoing access, Sesterce supports exporting expenses to a table, which avoids handing over the group password at all. Otherwise, for anyone who will keep adding or checking expenses, the identifier-plus-password route is the intended way to bring them in.

Is Sesterce free to use?
Yes, Sesterce is free for most of what it does. The site states plainly that it is "the best app to share expenses for free," and that some advanced features sit behind a Premium package. So the core job — creating a group, adding expenses, seeing who owes what — is available without paying, while extras may not be.
What "free" covers in practice
- Group expense tracking for couples, friends, roommates or colleagues
- Automatic balance calculation after each expense is added
- Web and mobile access, so members can check the group from either
- Exporting expenses to a table
- No account required to start using it
- Optional password protection on a group
Where the trade-off sits
The free tier is aimed at everyday splitting rather than heavy or specialised use. If your group only needs to log shared costs and settle up, the free version should be enough. If you want the advanced features, you would need Premium — the site does not spell out on this page what those features are or what they cost, so check the app itself before assuming a particular tool is included.
A useful next step
Create a test group for something low-stakes, such as a weekend trip or shared household bills, and invite one person. That tells you quickly whether the free feature set matches how your group actually splits costs — for example, whether you need uneven splits, recurring bills or currency handling — before you commit to using it for a larger group.
For comparison, other group-expense tools include Splitwise and Settle Up; each handles free-versus-paid limits differently, so it is worth checking whether the features you rely on sit on the free side.
Why should I use Sesterce instead of other expense-sharing apps?
Sesterce is worth considering if you want to split group costs without asking everyone to sign up. Its page states that you can use it without creating an account, that a group can be joined using a group identifier plus password, and that members can be added even if they do not have accounts. That combination is the main practical difference from apps that treat account creation as mandatory.
Use it when the group is fluid — a trip, a shared flat, a couple, or colleagues — and you do not want to chase people into installing and registering before they can participate. The page also says expenses can be tracked on web, Android and iOS, and exported as a table, which helps if someone wants to check the numbers outside the app.
The trade-off is that an account-free, password-based model puts more responsibility on whoever runs the group. If the group identifier and password are shared carelessly, access is less controlled than an app tied to verified individual accounts. For a trusted group, that is usually fine; for a large or public group, it is a reason to be careful.
H3 How to decide
- Choose Sesterce if low-friction joining and free core splitting matter most, and your group is small and trusted.
- Choose an account-based alternative if you need strong identity checks, formal audit trails, or organisation-level controls.
- Check what the page calls "advanced features" under Premium before committing, since the free tier is described as covering most, not all, features.
A useful next step is to create a test group with two or three people, add one expense, and confirm the balance and export behave as you expect before using it for a real trip or household.
Alternatives to compare against include Splitwise and Tricount.
Can I use Sesterce without creating an account?
Yes. Sesterce is designed so you can start without signing up: you create a group, add expenses, and the app calculates each person's balance. The page explicitly states "No email required" and that you can use Sesterce without creating an account.
What that means in practice
- Group access: Each group has its own identifier and an optional password, so people can join a group without registering.
- Adding members: You can add people to a group even if they don't have an account.
- Cross-platform: The same group can be viewed on the web, Android, or iOS, and expenses can be exported as a table.
- Limits: The site notes that some advanced features sit in a Premium package, so the no-account route covers the core expense tracking and settlement, not necessarily every extra.
A quick decision rule
If you just need to log shared costs and see who owes whom—say, a weekend trip or a shared flat—using it without an account is fine. If you want long-term history, recurring groups, or the advanced features, check what Premium includes before relying on the anonymous setup.
Next step: Create one test group with two or three people, add a couple of expenses, and confirm the balances and password-protected sharing work the way you expect before inviting the whole group.
For comparison, you might also look at Splitwise or Tricount, which take similar approaches to group expense splitting.
