RapidSplit

Those who ride along pay along. Those who don't, don't. RapidSplit settles kayak, club and group trips fairly: leg by leg instead of flat rates.

🛶 PER-LEG TRAVEL COSTS

Set up your trip as legs (e.g. outbound, shuttle, return) and mark who rode along on each leg. Only those people share that leg's costs. Settle via a per-km rate or by fuel costs split by kilometre share.

💶 EVERY COST OF THE TRIP

Assign driver expenses (tolls, parking, permits) to individual legs Shared expenses like groceries or campsites, with multiple payers if needed Foreign currencies with stored daily rates Optionally combine club or family balances into one group Manage several trips in parallel

✅ A CLEAR RESULT

Costs per person, balances and "who pays whom" with the minimum number of transfers. Export as PDF or CSV for records and sharing.

🤝 SETTLE TOGETHER
