1) It's free2). The app is very user friendly3.) You can use all of them at once4.). A lot of different sizes5.), Customized shapes are available6), Can be used easily with Photoshop7); If there was some way that they could add more social media apps like Facebook & Twitter then this would make things easy even if only by just selecting from their list rather than having your own customizations done manually.- No cons really! So far so goodI have been using most recently Instagram (Themes/Designs section or Filters tab when viewing my feed)- For creating new designs as well as finding what other designers out here might want which helps me create something unique too!!
