From the developer:
iWalk is a simple application that reminds you to take a break from your computer work, to get up, walk, and be healthy. Watching a computer screen for long periods of time makes your eyes dry, itchy, and will strain your eyes, which will eventually affect your vision. Ophthalmologists recommend blinking, as it refreshes the eyes naturally. iWalk is an app that can remind you to blink your eyes and also to take your eyes off the screen.
