Timmy
Group Expense Management
Timmy keeps a ledger for every trip, household, or group of friends. See what you owe, split a bill across the people who were there, and add an expense even without a connection. It stays on the device and syncs to the group when you are back online.

01
Every group, one ledger
The home screen is your ledger: each group, how many people and expenses are in it, and the balance you owe or are owed. Search the list, or start a new group.

02
Inside the trip
Open a group for the running balance, then switch between expenses, balances, and insights. Each line shows who paid, the total, and your share.

03
Split it while it’s fresh
Enter the amount, what it was for, and the date. Attach a receipt, mark who paid, and split equally, unequally, or by percentage across the people in the group.

04
The people you split with
Invite someone by username and keep that list close. The same friends show up when you choose who paid and who shares an expense.

05
Dark, light, or system
Appearance follows dark, light, or the system setting. If you used Timmy v1, you can request that older data from the same screen.

Offline
Add the expense. Sync it later.
You can add an expense without a connection. It stays on this device and syncs to the group when you are back online and signed in.
