I also use Inoreader (on both Android and iOS). They have an app for both platforms as well as a Web interface. You can also usually access your feed with them in third party RSS apps (as long as the app supports it, of course).

One odd/annoying thing about using their native Android app on Samsung phones that have high-rate touch interfaces - the app gets finicky about reading long-press touches (like when long pressing on an article to perform a “mark all above read” or “mark all below read” action). It usually takes me multiple attempts to get my touch to register properly with the app to be able to do those actions. (I contacted them years ago about it and they said they were aware of the issue but didn’t know when they’d get around to fixing it. Given how long it’s now been, I doubt they’re ever going to fix it). :(
