Cons
Con Trackers!
Con Unskippable Ads
Users are forced to sit through a timer window every day before the ads will skip (for that day). Stupidly poor idea for a "Business" focused calendar app.
Con Isn't multi-platform
No option to manage from PC, it would be cool if there was multi-platform for this app as website, Windows App, Mac OS, etc.
Con Support
Con Needs root (by design)
Needs root to update the hosts file.
Con Won't block same domain ads
Because the host file can only redirect domains, if the ad and content are on the same domain the ad will be displayed.
