I built Dyced after one too many group trips where the "who owes who" spreadsheet died on day 2 and nobody got paid back for a month. Dyced is a free iOS app for group trip planning and expense splitting. Plan together with a shared itinerary everyone can see and edit. Scan receipts — Dyced reads the line items, not just the total, so splitting one restaurant bill per-item takes seconds. Split evenly, by percentage, or per item. Smart settlements compute the fewest payments needed to make everyone square. Multi-currency for international trips, and a shared memories album so everyone's trip photos live in one place. Free on iPhone & iPad, no ads, no in-app purchases.
