The most annoying part of scheduling meetings with people is the back-and-forth emails to figure out a time that works for both people. Calendly is what I use and highly recommend to make scheduling a breeze! You just choose time slots, connect it to your Google/Outlook/iCloud Calendar and the person can schedule a time that works for them and already know works for you! It is completely free (unless you need certain options, I use the free version) and it is very pretty which is a must for me.
