Every rupee, and every change, on record
Trust is easier when everything is visible. ttmm keeps a full, searchable history of every expense, payment and edit.
The Activity tab
Activity shows everything that happened across your groups and friends, newest first: “You added ‘WiFi’ ₹1,178, you lent ₹884”, “Rahul paid you ₹1,255”. Filter it by group, search for any word (“swiggy”, “rent”, “Neha”), and react or comment right there.

Edit history on every expense
If an expense is changed, ttmm keeps the old version. Open any expense and tap History to see every change: “Amount ₹1,200 → ₹1,400, edited by Aman, 14 Oct”. It stops quiet edits and settles arguments in seconds.

Group history and monthly statements
Each group has a history with filters for money, people and settings changes. The Statement works like a bank statement for the flat: opening balance, your share of expenses, what you paid, settlements and the closing balance for the month, with your biggest expenses listed.

Exports
With ttmm Pro you can download statements as PDF and your expenses as CSV for a spreadsheet, which is handy at the end of a lease or for keeping records.
Questions
Can I delete an expense?
Yes. Deleting is recorded in the group history so everyone can see it was removed.
How far back does history go?
All the way back to when the group was made.
Are statements free?
Viewing statements is free. PDF and CSV exports are part of ttmm Pro.
