⚖️ Splitting Methods Explained
⚖️
Equal
The total is divided equally among selected participants. The most common method for shared meals and trips.
💵
By Amount
You specify exactly how much each person owes. Perfect when someone had a more expensive item or opted out of part of the bill.
🎯
By Share
Enter a weight for each person (e.g. nights stayed in an Airbnb). SplitSphere calculates proportional amounts automatically.
