I have the Chrome browser on my Iphone 6 and turn my phone to landscape orientation then just come to RFf through the browser. The screen is just big enough for me to see posts well enough to read if I zoom in so that just the main body of the post fills my screen--this does cut off the left edge of the screen just after the poster's info, avatar, etc are and while this works ok for text, looking at any photos here is not very good on the small screen.
