No dong? Add them as a guest

Adding a guest only takes a name — split expenses with them without them installing dong. If they join later with the same number, they confirm the switch themselves before anything moves to their account.

What does “dong” mean?

“Dong” is each person’s share of a shared cost

dong (Persian: دنگ) is a free expense-splitting app built for Iran: you log an expense in Toman, pick who shares it, and dong works out everyone’s share and who owes whom.

In Persian, dong means each person’s share of a shared bill. Whether you’re splitting the costs of a trip, a restaurant bill with friends, or household bills with roommates, everything stays in one clear, trackable ledger — no calculator, no notebook, and no balances lost in the group chat.

Where is dong useful?

Anywhere a few people share costs

Trips

Log lodging, food, fuel, tickets and shopping, and know exactly who owes what when the trip ends.

Restaurants and get-togethers

Split the bill equally or unequally, without working out anyone’s share by hand.

Home and roommates

Log rent, utility bills and groceries so nobody’s debts get forgotten over the month.

Gifts and parties

When several people chip in for a gift or an event, keep everyone’s share clear.

FAQ

Questions you might have before starting

What is dong?

In Persian, “dong” means each person’s share of a shared cost. The dong app (dongit.ir) records shared expenses and works out everyone’s share, debts and credits, so balances stay clear between friends, roommates and groups.

Is dong free?

Yes. Right now every dong feature — logging and splitting expenses, groups and settling up — is free, and you don’t need a bank card to sign up.

Is dong only for trips?

No. dong works for trips, restaurants, get-togethers, shared homes and roommates, gifts, and any expense shared between several people.

Can I split an expense unequally?

Yes. Split it equally, by percentage, or by a custom amount per person.

Does everyone have to share every expense?

No. For each expense you choose who shares it and how much each person’s share is.

Do I need to install an app?

No. dong works in the browser on your phone or computer, and you can add it to your home screen like an app. Friends who don’t use dong can be added as guests with just their name.

Does dong work in Iran without a VPN?

Yes. dong is built for users in Iran, its servers are in Iran, and you don’t need a VPN to use it. You sign in with your mobile number and an SMS code.

Can I use dong for trips abroad?

Yes. dong’s default currency is the Toman, but you can choose US dollars, euros or pounds too. The app is available in Persian and English, with dates shown in the Jalali calendar.

Does dong connect to my bank account?

No. dong has no access to your bank account and never moves money. When you pay someone back by card transfer or in cash, you record it in dong and the balances update.

Is my data safe in dong?

dong only keeps what you enter yourself, like expenses and who shares them, and only the members of that expense or group — plus anyone you send a group link to — can see it. The full details are in the privacy policy.

Does it work offline?

Without internet you can still view what you’ve already opened; logging a new expense or settlement needs a connection.

How is dong different from Splitwise?

The idea is the same: log and split shared expenses. But dong is built for users in Iran from the ground up: a full Persian interface, Toman as the default currency, the Jalali calendar, sign-in with your mobile number, and access without a VPN.

How it works

Three steps to a clear balance

1

Add an expense

Enter the amount, who paid, and who it's shared with — a friend or a whole group.

2

dong splits it

Each person’s share is worked out the way you chose to split it.

3

Settle up

Record payments as they happen, and everyone’s balance stays up to date.
