For many years, I have been using a paid subscription competitor application. When I saw Publytics LTD on AppSumo, I immediately bought Tier 1 and started testing it.
Publytics offers almost the same tracking information, but not all of it. For instance, I cannot see the city where my visitors are connecting from or which internet service provider they are using.
On the other hand, Publytics does not implement cookies, which largely explains the lower level of visitor details.
The UI also lacks some settings that would come in handy. For example, when switching back and forth between my two websites, upon returning to the first site, the default view only shows pageviews, while I had selected to view both pageviews and users before.
There is also no option to view both of my websites on one page, apart from the Global Real Time page. I would like to see both of my sites together on the Audience (or any other) overview page.
However, none of these minor issues will keep me from using Publytics further.
