Baluchon

Baluchon helps you manage shared expenses with friends or family during a trip (vacation,
weekend, group travel...), or share costs over time with a "shared account" (for example
kids' expenses between separated parents).

Main features:

• Create a trip and group your participants by family (optional).
• Assign a weight to each participant (normal share = 1, half share for a child for
example), individually adjustable for each expense.
• Record your expenses, dated and named, with one or more payers (total amount calculated
automatically, simple calculations accepted like "12+8").
• Choose precisely who is concerned by each expense.
• Shared accounts: add the children, attach expenses to them and set the split between the
parents per child, with exceptions by category (for example 50/50 for health, 70/30 for
activities). Recurring expenses are created automatically, and periods close
automatically once the accounts are at zero.
• View each person's (or family's) balance, the total trip cost per person, and the
minimal list of reimbursements to make.
• Record a real transfer between two people to settle up.
• Handle multiple currencies with a custom exchange rate per expense.
• Export the full summary as PDF, or as JSON to share between devices and merge expenses
from several participants at the end of the trip.
• Import participants directly from your contacts.
• Duplicate a trip (participants and families only) for a recurring trip with the same
group of friends.

Baluchon is completely free, open source (GPL-3.0-or-later license), ad-free, with no
account required, and works fully offline: all your data stays on your phone.
