Golden Ratio Overlay
Composition grid over any app
Only for Mac
$2.99
Mac
The composition overlay your editor is missing: rotate and flip the golden spiral over any app - now with global keyboard shortcuts.
Golden Ratio Overlay floats a composition guide over anything on your screen - your photo editor, design tool, video app, or browser - so you can compose against the grid you actually want.
Built for one reason: most editors can't rotate or flip their built-in overlays. This one can. Every guide supports all eight orientations; rotate in 90-degree steps or flip horizontally and vertically with one click.
GUIDES
• Rule of Thirds: 3x3 equal grid
• Phi Grid: golden-proportion grid (1 : 0.618 : 1)
• Golden Spiral: Fibonacci spiral with its golden-rectangle subdivisions
• Golden Diagonals: corner diagonals and their reciprocals
• Harmonic Armature: the classic 14-line armature
• Center Cross: centered midlines
FAST FROM THE KEYBOARD
• Global shortcuts for every overlay action: show or hide, cycle guides, flip, rotate, and lock - they work while any app is in front
• Remap every shortcut in Settings, or clear the ones you don't need
• Hold Option while the overlay is locked to move or resize it; release and it snaps back to click-through
• Open at login so your guides are always one keystroke away
MADE TO STAY OUT OF YOUR WAY
• Lives in the menu bar; no Dock icon, no windows to manage
• Floats above every app, including full-screen ones, without ever stealing focus
• Lock mode makes the overlay click-through so you keep editing beneath it
• Drag to move, grab a handle to resize; hold Shift to keep the aspect ratio, Option to resize from center
• Six line colors with a contrast understroke that stays readable on any image
• Remembers your guide, color, position, and orientation between launches
PRIVATE BY DESIGN
No data collection, no analytics, no network access. The complete source code is public on GitHub.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
The overlay is now at your fingertips - control everything without opening the menu bar.
NEW
• Global keyboard shortcuts: show or hide the overlay, cycle guides, flip, rotate, and lock from anywhere. Defaults use Control+Option; remap or clear any of them
• Settings window: record your own shortcuts, reset to defaults, and pick launch options (open it from the gear in the menu bar panel)
• Hold Option while the overlay is locked to move or resize it without unlocking - release and it is instantly click-through again. Prefer Command or Control? Change it in Settings
• Open at login, and optionally show the welcome window at every launch
IMPROVED
• Tooltips now show each control's current keyboard shortcut
• Shift (keep aspect ratio) resizing works seamlessly while adjusting a locked overlay
