PulseTiles is a macOS menu bar app that snaps any window into halves, thirds and quarters on every display. Hold ⌘ and drag onto a zone with a live preview, press a ⌃⌥ shortcut, or type a layout into the ⌘ + / launcher. No account and no analytics, with a 7-day free trial and then $4.99 once. One licence covers 3 Macs, with a 30-day refund. It also saves window arrangements, records custom shortcuts, keeps gaps between windows and moves windows between displays. Native Swift, Universal for Apple silicon and Intel, macOS 14 Sonoma or later.
PulseTiles only snaps while you hold ⌘ and drag, with a live preview of the zone, so ordinary drags are left alone. ⌃⌥ shortcuts cycle half, third and two-thirds sizes, a type-to-snap launcher covers the rest, and whole-desk arrangements can be saved and brought back. For people who want the window they are using to go where they point, without a full tiling window manager.
