I just love it, It's very useful as you can send any file like audio/video files or documents in one click to all your contacts! You have an unlimited number of contact who are sharing this app with you for free which is amazing!! nothing much that i dislike about whatsmany so far but if there was something then its would be great. The best part being able share multiple things at once without needing extra apps etc.. If u dont know how using whatsmany feel scared when first time use cause many people will make fun off ur lack knowledge by saying "what" whos sending me? But trust us after we tried they wont even remember why made them laugh because thats not funny anymore ;) So try out what smaNY doen't cost anything either download from play store (free) OR get premium account ($1 per month). Sharing pictures easily across platforms & devices via chat windows has become easier now thanks to.
