I read about the product Airtime around a year ago in Technolawyer. I immediately asked my assistant to try and get me a copy. She was unsuccessful because Airtime did not have a version that worked on Palm based Smart Phones.
One of the first things I did when got my Windows Treo 750 was to call Airtime and get a demo. Airtime provides automated time-capturing solutions for Smart Phones. Before Airtime, at the end of every month, I would print out a copy of my phone call log, and look for the long calls that I could bill for. I really had no way of tracking emails. This is not a very effective system and a lot of billable time and money was lost. Airtime promised to solve this problem.
The installation was fairly simple. You have to download Microsoft SQL Version for mobile phones and then the product itself. Once I set it up on my phone, I exported a client and matter list from PCLaw and imported it into Airtime. (Expect a White Paper detailing this very soon.)
It is a very easy product to use and their support team is more then willing to help train you on the product. After a phone call or email, Airtime comes up and asks me to choose a Client, Matter, Explanation and Task Code for the phone call or email. I can also type in a description. This information is then sent to the Airtime server where you can export it into a CSV file and import it into PCLaw.
Airtime has settings that allow you to specify thresholds that will open the billing screen if the phone call or email is a certain amount of minutes long. It also has a stopwatch feature that allows you to track time that is not a phone call or email.
PCLaw TE is not available for the Windows Smart Phone and frankly Airtime is a superior product.
