I like to use it as an additional tool for my designs when needed (i'm using Photoshop).
It's easy enough even if you're not familiar with Adobe products or software in general but still gives results similar than other programs such us InDesign CC which i personally prefer because its free! The only thing about this program would be maybe more options could exist so we can change some settings depending our needs without having too many choices at once causing confusion during usage instead just adding one option here another there etc.. nothing really bad though :) great app overall very helpful sometimes especially while designing webpages/websites since eye tracking helps me know better exactly whats being seen most often & used frequently among visitors / users!
