Synodi

Planning a trip with friends shouldn't mean juggling spreadsheets, group chats, and awkward money conversations. Synodi brings everything together in one place- so you can spend less time organizing and more time actually enjoying the trip. FAIR EXPENSE SPLITTING Most expense apps assume everyone splits everything equally. Real trips don't work that way. Synodi is built around proportional splitting- so the person who skipped dinner doesn't pay for it, and the person who stayed two nights pays half of what someone who stayed four nights pays. Split expenses by participation, by nights stayed, or set custom amounts manually. The math is transparent, fair, and easy for everyone to understand. SETTLE UP SIMPLY See exactly what you owe and what you're owed at a glance. Synodi calculates the minimum number of transactions needed to zero out all balances- so instead of a web of payments between nine people, you get a clean list of who pays who and how much. Store your payment handle in your profile so your trip mates always know how to pay you back. Mark payments as sent and received, and watch your balance update in real time. PRIVATE AND INVITE-ONLY Every trip is private. Only people you invite can join. No public links, no strangers, no surprises. BUILT FOR THE WAY GROUPS ACTUALLY TRAVEL Whether it's a weekend cabin trip, a bachelorette party, a family reunion, or an annual friends trip- Synodi handles the details so you don't have to. — Fair proportional expense splitting — Debt simplification to minimize total payments — Payment handle storage — Real-time balance tracking — Private invite-only trips — Individual accounts with secure sign-in — Currency support Download Synodi and make your next group trip the easiest one yet.
