I love that you can send out reminders to clients about their appointments, as well as have access all information online! It is also nice because it has an option for adding multiple pet sitters so if there are more than one client at home with pets we don't need everyone's login info over & again just once time when they log back into our website (which happens frequently). There isn’t much dislikes from me but would like some improvements such as being able to change font sizes easier/more options available under "settings". My only other suggestion may be having two separate pages instead of 1 page showing each appointment made by different providers which makes things difficult sometimes especially since my computer screen doesn't always fit perfectly onto both screens side-by-side due to size differences between them etc.. This app saves us SO MUCH TIME.
