Here is some good advice and i have been using this a while.
Okay alot of us have been using these programs for our appointments when things are due and so on but wouldnt it be great to have your calender updated from the office but accessed from the job on your phone?
I have been using Google Calender and i tell you my appointments i can access any time and during bids i can look at the calender anytime and advise the customer of a day available to set them up right there.Been helpful toards my business and hoping it is towards yours.
At home i use Microsoft Outlook to keep up with all appointments and also it tells me when things are do and the great thing it works together with Google.
