Weatherling
Weatherling makes rain fall among the windows you already have open. Drops land on the top edge of a window, gather along the edges and in the corners, and run down the sides. At high intensity the edges overflow into small waterfalls.
It is an ambient visual effect, not a forecast app. There is no temperature, no radar, and no seven-day outlook. You decide whether it is raining, and how hard.

The idea
Most desktop weather is a wallpaper or a particle layer pasted over everything. Weatherling is built around depth instead: it knows the front-to-back order of your windows, so a drop can fall in front of one window and behind another, and water that lands on a title bar belongs to that window.
Move a window and its water moves with it. Bring another window forward and the rain behind it disappears where it should.
How it behaves
The overlay is click-through and never takes focus, so you keep typing, scrolling, and dragging as if it were not there. Everything is controlled from a small menu bar popover, and Option-clicking the cloud turns the rain on or off instantly.
- Rain intensity from drizzle to downpour, with runoff and waterfalls that scale with it
- Depth, wind, and quality controls
- Per-display rain, and an option to draw over full-screen apps
- Optional rain sound, off by default, that fades out while any app uses the microphone
- Metal rendering with a procedural wet-glass look
No permissions required
Weatherling never asks for Screen Recording or Accessibility. It reads only the window positions macOS already shares with every app, never window contents and never window titles. The app makes no network requests and collects no data: no account, no telemetry, no analytics.
That constraint shaped the whole design. The wet-glass look is procedural shading, not a capture of the pixels underneath, because capturing them would have required a permission a decorative app has no business asking for.
Requirements and price
Weatherling runs on macOS 14 (Sonoma) or later, on Apple silicon and Intel Macs, and is sold on the Mac App Store for US$1.99, paid once. No subscription, no in-app purchases, and updates are included. Rain is the only weather today; snow and sunlight are planned.
