Startup Idea : Decrease Divorce Rate

The idea is to create an app that a couple will use to remain on the same page with each other as forgetting the strong commitments with time leads to differences and distances leading to end result of divorce. In this app both will keep track of commitments (with some conditions on each) list maintained (changing anything will need approval of other). In this way, one couple will remain on the same page and there will not be wrong expectations. It will decrease the divorce rate in the world.
