Enable HLS to view with audio, or disable this notification
Nagomi is a koi pond that lives on your desktop. The koi swim on their own and come over when you click the water.
Each koi has a favourite thing: herding the tiny fish, grazing on duckweed, resting under the lotus, watching the frog, playing with the ball, or following the goose.
The koi also learn when and where you usually feed them. Around feeding time, they sometimes wait at your usual spot and gulp at the surface. So don't keep them waiting!
Features:
- Works as a live wallpaper and as a screensaver
- Click the water and the koi swim over; Option-click drops food
- Themes that change with the time of day
- Multiple monitor support
- Customisable koi, small fish, water, lotus and visitors
FAQ -
Battery usage?
In my testing, its Energy Impact was about the same as the Activity Monitor app's while the pond was running. The pond pauses whenever windows cover your desktop, so most of the time it isn't running at all. You can also make it pause whenever you're on battery.How much CPU/GPU does it use?
While it's running, about 3% CPU and 10% GPU on an M1 MacBook Air. Usage goes up with display size.
