I have no qualms with the statistics part. It (seems) to do its job and it clearly shows me where I have spent my time, but the association with "rooms" (a.k.a., desktops) is buggy and hackish at best.
At least under Catalina, it changes how OS X mission control works, yet is not able to name the Desktops everywhere.
If you have multiple monitors, activating the menu leads to "flashing" of the application in and out, taking five or more trials just to activate it. It's clear its hacked architecture does not really support more than one screen.
Given that the main purpose for which I got this app was to abe able to name the desktops appropriately (something that Apple should be doing), it is not working for me.
Hey there! Thanks for pointing out the flickering popover issue -- I'll address that in the next update, which should be out in a couple weeks, with some big features too. Multiscreen usage is supported but your issue happens to only occur with multiple screens. Sorry you ran into that.
-- It is indeed a shortcoming that Mission Control's Desktops can not be renamed, I have squeezed everything I could, functionality wise, out of Mac's Public APIs. I can't say I did anything wrong, it's simply not possible for an app from the App Store, or one that does not disable SIP protections, use private APIs, etc. to accomplish that request.
