I've been using Clickbook for over 4 years and we love it (me & my clients). My clients love being able to plan & book appointments at night or when they are home during the day and the auto reminders are a godsend. I love being able to manage my diary from my iPhone calender using the simple 1 time sync and now auto-updates all new booking, changes etc with even having to go online - Love this feature. Importantly - anytime I've needed a helping hand - ClickBook has always come back to me quickly & we've always sorted things out easily. I am a BIG fan of Clickbook and have referred many of my peers to use it as well.
