A macOS menu-bar utility that places the active window with hotkeys and three-finger trackpad swipes: halves, full screen, a centered third — on any of your displays.
- Recognizes a swipe only when exactly three fingers move together in one direction, so ordinary scrolling and resting palms don't affect your windows.
- Swipe angles can be calibrated to your hand in about a minute.
- Light on resources: under 1% CPU when your fingers are off the trackpad.
- Prevent Sleep: keep the Mac awake on demand — indefinitely, for a set duration, until a chosen time, or with the lid closed — plus an optional battery-side Deep Sleep (hibernate) profile.
| Input | Action |
|---|---|
| ⌃⇧← / ⌃⇧→ | left / right half of the current screen |
| ⌃⇧↑ | maximize |
| ⌃⇧↑ ↑ (double press) | full height, centered, ⅓ width |
| ⌃⇧↓ | restore the window's previous frame |
| ⌘⌃⇧← / ⌘⌃⇧→ | halves on the next display |
| ⌃A | lock the screen |
| 3-finger swipe ← / → / ↑ | left half / right half / maximize |
| ⇧ + 3-finger swipe ← / → / ↑ | left third / right third / centered third |
| ⌘ + 3-finger swipe ← / → | halves on the next display (⇧ combines: thirds) |
Swipe-down, two- and four-finger movements do nothing. The full reference lives in the app: menu bar → Tiler.
The menu-bar Prevent Sleep section keeps the Mac awake on command — indefinitely, for a fixed duration (10 min … 24 h), or until a specific time. The menu-bar icon turns red with a coffee-cup badge while a session runs.
- Keep display awake (Settings → Power) also holds the screen on; off by default, so only the system stays awake.
- Battery floor (default 20%) auto-stops a session on battery once the charge drops to the floor, with a notification and no surprise restart.
- Prevent sleep with the lid closed runs the Mac folded; it needs an administrator password and gets hot — never leave it in a bag.
- Deep Sleep on lid close (Settings → Power) switches the battery-side sleep profile to full hibernation for near-zero drain; wake then takes ~10–20 s.

Window-tiling hotkeys (⌃⇧ arrows) are off by default — turn them on in Settings → General if you want them alongside the gestures. The ⌃A lock-screen hotkey is on by default.
Requires macOS 15 or later — universal binary (Apple Silicon + Intel). Tiler targets macOS 26 and is verified on 26.5 (Apple Silicon); older versions can run it, but are untested for now.
Open Tiler → Settings → Gestures → Calibrate — a guided one-minute dialog adapts recognition to how you actually swipe. If system three-finger gestures (Mission Control, three-finger drag) are enabled, Tiler will point at the exact setting to change.
