Automatically capture the screen when it changes.
Yes, only when it changed and you can configure the sensitivity!

Want to monitor or keep track of your computer usage? With ScreenLog, you can keep a log of screen captures of your computer sessions. However, unlike other apps, ScreenLog doesn't take screen captures based on a set time interval, but by the present screen's percent deviation from the last screenshot, making it much more efficient and usable.

Simply make your screenshots into a daily movie with our app named "picture2movie".
