FreeRange: Powerful RSS reader for mobile phones

Previously, FreeRange was a paid app, with free users limited to 10 feeds, but now it is completely free and there is no such limit. However, it should be noted that if you want to use FreeRange normally, you need to register a FreeRange account first, which is also free of charge. Similar to viigo, this account allows you to manage your feeds from both mobile and PC.
