I downloaded this demo, and it's just that - a VERY limited demo; some buttons don't seem to work, it's too small to really see (and I've got perfect vision), and the list of activites and other things is very limited, leaving much to be desired if he wants to sell anything. your activity is limited to hours only, not minutes, and good luck picking a different number of hours than what's offered or defining a new activity that's not listed. There are better apps that do this, but this was the first widget I've checked out.
