Split any expense the way it actually happened

Not every bill is a neat three-way split. Someone skipped dessert, two people paid, the WiFi is shared by four but the AC by two. ttmm handles all of it in a few taps.

Start with the amount

Adding an expense starts on a big calculator keypad, because the amount is the one thing you always know. Type it, add a short description like “Big Basket order” or “Swiggy dinner”, and you’re already done for an equal split. ttmm fills in today’s date, assumes you paid, and splits it equally between everyone in the group. You can change any of those with one tap on the pills under the amount.

Six ways to split

Tap Split equally to open the split sheet. Each way of splitting answers a different real-life question:

As you type, the sheet keeps a running check at the bottom (“Adds up across 4”, or “₹120 left to assign”) so you can’t save a split that doesn’t add up to the bill.

Item by item, with tax and tip done properly

Restaurant bills are where most splits go wrong. With Items, add each line from the bill (Pizza ₹600, Beer ₹400…) and tick who had it. If the bill total is higher than the items because of GST or a tip, ttmm spreads the difference in proportion to what each person ate, not equally. So the person who had a ₹100 coffee doesn’t pay the same tax as the person who had a ₹900 platter. The expense keeps the item list, so anyone can open it later and see exactly why they owe what they owe.

When more than one person paid

Cards get declined, UPI limits run out, and sometimes two people split the payment at the counter. Tap Paid by and choose Multiple people, then enter how much each person paid. ttmm checks that the payments add up to the bill (“2 people paid ₹900”) and works out everyone’s balance from both sides: what they paid and what they owe.

Receipts, notes and the date

Every expense can carry a photo of the receipt, a note (“includes Rahul’s extra cheese”) and a different date if you’re adding it late. Anyone in the group can comment on an expense or react to it, which settles most “what was this ₹840 for?” questions without a single phone call.

It warns you about duplicates

When two flatmates both add the same Zepto order, the balances go wrong quietly. If you add an expense that looks like one already in the group (same amount, close in time), ttmm asks before saving it twice.

Edits are tracked

Expenses can be edited by anyone in the group, and every change is recorded: who changed what, from what, and when. Open an expense and tap History to see it. Nobody can quietly change a number.

Tips from real flats

• Agree on the default once. Most flats split groceries equally and only use Shares or Items for meals out. Agree on that when you move in.
• Use Items for anything over ₹2,000. The bigger the bill, the more an equal split hides.
• Split the AC, not the bill. For electricity, split a base amount equally and only the extra by AC use. Our electricity calculator does the maths.
