It's very simple to use, it has all of my contacts in one place so I don't have to search for them every time! Nothing really at this point but if you're looking into call sheets then definitely check out pocketcallsheet because they are great!! If your not using pocketsheets yet or haven't heard about their products maybe consider giving that app/website try as well just see what works best with how many people work together within an organization - there is no right answer here only personal preference. We've been able to organize our calls much better than before by putting everyone who needs access straight onto the sheet which makes communication easier between teammates when we need input from someone outside of us.
