For bills involving multiple people, settlement often becomes a tricky issue. Different payers and participants make the entire process complex. Manual calculations tend to result in unnecessary transactions and amounts. Splitant is developed to tackle these challenges. With robust algorithms, Splitant makes settlement quick and easy. You can specify the payer and participants of each expense, and flexibly choose how to split it. The final result is optimized to minimize the number of transfers and the amount that needs to be transferred. When multiple people travel together, you no longer have to rely on the same person to make all the payments first, and other people will then transfer money to this person. There are also no worries about redundant transfers, such as A transfers money to B, and B transfers money to C. From now on, payments will be flexible, settlement will be easy. Key features: * You can set different payers for different expenses. * You can select who needs to share an expense. * You can specify how to split an expense. * Settle within a minimal number of transfers and amounts. * Data is safely stored in iCloud.
