Adnova really impressed me.  It is a beautiful, very clean UI, so you can focus on the ads with a minimalistic and nonevasive clean view of the creatives that aren't disruptive like other Ad Spy Tools.  It is game over once they catch up with their competitors regarding the size of their Advertisement database and the number of Ad Channels.  I already like the tool way better than most ad spy tools.

Right now, the filtering is essential, but the team is working on making it more robust to better narrow in on your target ads and creatives. Unlike other ad spy tools, it provides unique features like creating a creative workflow. It is trying to be an all-in-one tool, which it is doing well.

I have bought a lot of AppSumo software, and this one got me excited. I will continue sending feature requests in their roadmap portal to ensure they beat out their competitors!  Do not miss investing in this software before it goes away. I already purchased Tier 3 and am glad I did.
