Still can’t remember keyboard shortcuts? Still awkwardly dragging windows to the edge of the screen?
Try Gridly — it’s seriously good. Just place two fingers on any window’s title bar and swipe smoothly. The window snaps into place instantly.
Swipe left or right → split the screen in half
Swipe up or down → fill the top or bottom half
Swipe diagonally (add a direction) → drop precisely into a quarter corner
Double-swipe up → maximize
Double-swipe down → restore to original size
While you’re swiping, a semi-transparent gray silhouette previews the exact position. The window only moves when you lift your fingers. Changed your mind mid-swipe? No problem — just keep sliding to where you actually want it.
No dense list of shortcuts to memorize. No hijacking your existing global gestures. It does one thing, and does it extremely well: manage windows with the most intuitive title-bar gestures possible.
It also works seamlessly across multiple displays, is built natively in Swift, runs extremely lightweight and quiet, and never gets in your way. It supports 7 languages, and the whole setup takes about a minute — download, flip on Accessibility permission, and you’re ready to enjoy the smoothness.
We give you a full 14-day free trial with every gesture unlocked. No account required, no credit card needed.
Gridly — window management that finally feels intuitive and effortless.

Gridly 1.0.7 Update
Added the ability to customize the window size to "moderate and centered". The slider in the settings ranges from 25% to 95%, with a default of 60%; the ratio is calculated based on screen area, with 25% corresponding to one-quarter of the screen.
The configured control colors are now consistent with the theme color.

Gridly 1.1.0 Update
Left and right swipes now go further than halves: keep swiping toward the same edge and the window steps through narrow — half — wide. Settings lets you pick the extra pair of widths (1/3 & 2/3, or 1/4 & 3/4). Swiping down three times minimizes the window; the third stroke must travel farther so it never happens by accident.
After you snap a window, Gridly can fill the space left over with your recent windows — automatically, or one candidate at a time with “Let me pick a window” (off by default). Changed your mind? Press Esc within five seconds and every window that moved goes back where it was.
Five accent colours (Gridly orange, Graphite, Blue, Green, Purple) now theme the interface, the window preview and the app icon. The About window shows your Accessibility permission at a glance, and swiping on Gridly’s own Settings or About windows no longer moves the windows behind them.

Gridly 1.1.1 Update
2026-08-30
Settings and Help have been reorganized: related options sit together, and Help follows the same structure so you can find a gesture without hunting.
Less-used gestures — width steps, restore, minimize, and Esc undo — each have a switch in Settings. Turn one off and the swipe falls back to the previous step instead of doing nothing. Half screen, corners and maximize stay on.
