Hey this is super easy to use, clean, and best of all free! (to an extent). If you are looking for a simple way of providing your clients with a list of your week availability without all the back and forth of time guessing, then this is the tool for you. You point them to a link, have them choose the time that works for them (and is available for you) and your done! Best of all is that SimpleBook.Me will add the appointment to your Google Calendar for you. And again … for FREE. 🙂
