I always tabbed back and forth between my Google calendar to construct a message that accurately listed my free time, but this was painful.
My site helps me do this small task, and I wanted to see if anyone else had this same problem, had some feedback for me, or if there were any other simple solutions and I've wasted my time building this crap.
Note: I've yet to have my app verified by Google, so if you wish to import your own Google calendar on to my site, the consent screen will look sketchy.
