ScreenGridy can draw a grid on your screen, which allows you to resize applications to a specific section of your screen.
ScreenGridy requires installation and resides in the system tray. You can right-click the icon at any time. From there, you can show or hide the grid and access settings, including the number of rows, transparency, and grid color.
In our tests, we found ScreenGridy worked well for most applications but could be a little flaky, sometimes resizing an application in a way that made that particular app challenging to use.
That said, ScreenGridy does address a common problem with sizing and snapping applications where you want them in Windows.
