TripFund is a trip expense tracker for the person who holds the group's money. Other apps work out who owes whom; this one records a shared fund and turns it into a report. Enter the amount, tap a category, done. Spend in any currency and read it in yours. Dues, donations and proceeds are kept apart. Export to Excel or PDF when the trip is over. No sign-up, works offline, no limit on entries. Free with ads. Android, 9 languages.
