I worked with Tim on our app Giffiti, which had 50k downloads on the first day in the app store. Tim's screenshot designs were a big part of that.
It's really exciting that Tim has made his best performing designs available to all.
In addition, LaunchMatic makes it trivial to internationalize your screenshots in a few clicks. When we internationalized our screenshots for Giffiti, we saw ~20% lift in downloads. This strategy is a no-brainier.
Great job Tim!
