Lasso

Drag across a grid to size and place any window

Mac$10.99 once

The verdict

Snap-to-half tools fall short when you want an odd size, like a narrow strip down the side of a wide monitor. Press a hotkey and Lasso shows a grid, so you drag across the cells to set the window's exact size and spot, and save layouts to their own shortcuts. It costs $10.99 once for 1 Mac, but the free Rectangle already covers halves, thirds and corners.
