I really enjoyed using this, but I had to remove it. When I looked at Activity Monitor, I saw that the app was using 11% of the CPU and Flash was using 14%. 25% of the CPU constantly being used is too much.

That said, it was a beautiful app and if the developer can get a handle on this CPU usage, I'll reinstall it and buy the pro version.

Dear Aeschylus, my name is Pasha, i am the author of YoWindow. Pay attention that YoWindow does not use any CPU when it is running in the background. So when you don't need YoWindow you don't loose on CPU. I am watching this problem very carefully. This has always been on Windows (where YoWindow is very popular) and it is the same on Mac OS.


Repkasoft, what you say is absolutely NOT true. I have screenshots of Activity Monitor. With YoWindow in the foreground, FlashPlayer (YoWindowInternet) takes 108% CPU, and YoWindow takes 13.9% CPU.

With YoWindow in the background, FlashPlayer (YoWindowInternet) takes 12.3% and YoWindow takes 9.4% CPU, for a total of 21.7% CPU IN THE BACKGROUND.

This is not good. Flash has always been better on Windows, so maybe this will take a different approach on the Mac.

My apologies, there must be some bug slipped inside Mac edition. I will check Mac performance within the next couple of days. If you want to help with catching the bug or if you want I to email you after the investigation please send a short email to suppor@repkasoft.com


I agree with @Aeschylus the app is the most useful, but it really uses enormous amount of cpu, even when closing the flash windows, also the menu bar interface needs to be Mac OS native. Also, there's should be an pre defined alert for when rain is coming for example, "Alert if rains above 4 hours"...
