Is there a program for ios to sync the list?

Question

iOS

Please help me find a program for ios.
It is necessary that several people have a list of people who have been given money synchronized so that they do not take it again.
For example, there are three directors from whom you can take money for construction, and a lot of workers who take money from these directors. It is necessary that each director sees who and to whom has already given money for the construction.
