In my opinion, this app has two great features.
1. You can send multiple people a calendar that allows them to click on what meeting times work best for them. Everything is synced to your Google Calendar so any existing appointments will be blocked off. When they select a time, it will sync back to your Google Calendar, so you don’t have to worry about missing a meeting. Everything happens from directly in gmail, so it is very easy to use.
2. From directly in gmail, you can quickly send screen shots of your calendar, which is handy for letting other people view existing appointments.
