The thing that killed the official Reddit app for me was the battery drain. It felt like three hours of browsing would be enough to drain my phone's battery. Also the video player was trash. So I jumped on a third party app. I later deleted it, as I felt I was spending too much time on Reddit, and stuck to accessing it on web browser more sparingly. Then I hear that Reddit is experimenting with preventing people from using a mobile browser to access it... Yeah, I'll break from them before I bend for their IPO.
