Yes, you should check out LivePlan. It is a web-based application, like Gmail. That means it works differently than CD-based software that you install on a particular computer and has multiple advantages. First, you can access and update your plan from any computer (Mac and PC) or tablet. Second, LivePlan’s online platform also allows their development team to update the software anytime without requiring you to install — or pay separately for — an upgrade. These updates typically come monthly without any effort on your part. Lastly, being cloud-based, the system is optimized to have others collaborate with you on the plan. It works well with Chrome, Safari, and Firefox.
