When Samsung Galaxy S4 was launched, Samsung officials talked about a new app called WatchOn, with which you could interact with your Samsung Smart TV.With it you could see the program guide and watch your favorite TV shows.
Samsung just unveiled how will this new app will look. It seems that it's design is similar to S-Voice app and the Life Times app expected on the new Samsung S5. It also shows that WatchOn will use KitKat 4.4.2 guidelines (so it has a better design ).
It seems that this new app will appear in March with S5's upcoming launch. If you don't have a Smart TV from Samsung, maybe it's the time to buy one !
