Pocket and @Voice apps tts. @Voice allows you to jump through text by double tapping and supports more sites and formats (PDF, etc.), but pocket manages your article list so much better so I use pocky 90% of the time.

Pockets uses a readermode view, so it's non tts UI is nicer, so if you don't care about tts just use pocket.

Firefox reader mode is also nice, Firefox preview is great.
