If you actually take the time to read the apps description then you wont be disappointed. Nowhere does it say you can make icon for native or downloaded apps. I have used this for several websites I frequent daily that dont have apps. it make my home screens look so much cleaner since the icon the websites give are not always great. I recommend this app to anyone who visits websites daily. Better than bookmarks in my opinion. I DO WISH THAT IT COULD GET AN iOS 7 MAKEOVER THOUGH. This app looks old and dated inside but it still works.
