They all must be automatically by the app should get lower ratting it a not too hard u need a better programmer that can write code such as if the person either party don't shower or check in at specific time at choosing location should automatically be handlelled so a person who tells you that at 7a.m meet me u wake up early and drive the person don't even reply back we need some kinda if you make appointment with some one u must keep it or ela there should be a fee so that way this app makes money as well and that way people will show or don't do stupid offers and meets. Thanks
