The best thing is that you can share your schedule with other people in order for them to know when they are free or not available so it helps me out alot since I am busy most times but still want others who need my help around during those hours as well. It's also good because if there was an emergency at work i could just go online from anywhere without having to worry about getting home first. Nothing really bad except sometimes some messages don't show up until after 2-3 days which makes scheduling difficult especially when its important like appointments/meetings etc. If anyone needs someone reliable to talk to while working then this app would be helpful! Especially if you have multiple projects going on at once. Scheduling meetings has become easier now thanks to VIAVOO!!
