This tool can assist anyone's work that trains others.be it industry or educational fields. The viewing and voice, in my opinion, are the greatest part of the end product provided to viewers. Viewers watch the video and listen to a voice quicker than reading remarks. #2 - students do not always read the added comments thoroughly. Of course, MS Word has the tracking changes option and a professor can go through sentence by sentence - the downfall of this is that students #1 - do not always understand what is being suggested as we all cut back on words when typed out versus spoken. There are other uses of course, one that I found was to capture myself talking through students' research papers/thesis and explain where changes need to be made. Unfortunately, the Mac App Store does not offer any provisions for upgrade pricing. This is good for the simple reason that funds are. The application allows me to video what I am doing in the application while explaining it in details. We check over 250 million products every day for the best prices. Users get many upgrades at no cost and those that cost are at an upgrade price which is very inexpensive.

When training others to use a software application, I find this is amazingly helpful to accomplish using screenflow.
