Pocket ( https://getpocket.com/ ). It’s really bad. Been using it for years and it’s always been broken. Crashes often, narration sometimes works most of the time it doesn’t, other times it works if you force stop the app and restart it. It’s very slow too. I depend on for my long daily commutes and I only stick to it because InstaPaper is also very broken and there is no reasonable way to move the stories from pocket to instapaper. I am convinced the people who build it never really use it for those issues are otherwise trivial to encounter and I would think trivia to fix as well. I hope someone will build a better such app and make them irrelevant.
