Baluchon helps you manage shared expenses with friends or family during a trip (vacation, weekend, group travel...). 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. * 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.
