I like that it allows us to have appointments scheduled publicly but internally we can schedule appts, and also edit our availibility. I like that it will sync to your Google Calendar and allows you to offer multiple "services." We use setmore daily and do love the easy of using it.

I use setmore daily to run my it consulting business, I'm a 1 man show, so the free tier of Setmore works great for me. It enabled me to include a booking page on my website and mobile app

The free account is a complete solution which allows you get your service up and running without investing in asubscription.
