"Relay" is also amazing. I realized just today that I browse HN from mobile Firefox, but reddit from Relay, and I realized that that's because Relay is so much better than any HN mobile app. It really makes a difference.
Yes, it's what I currently use, but it has some problems (comment formatting shows up weirdly, the built-in browser uses desktop mode and doesn't let me resize sites so many are illegible, etc). It's the best I've found, though.
Materialistic is nice. The only feature I miss with it would be a custom filter. If I could hide automatically stories based on keywords (like "Facebook"), that would be great.
