Nine years ago, I used an Android device for the first time on a Nexus 5X. Now, I'd like to ask for recommendations on some new apps. For those who may be interested, here are a few examples I'd like to share. First, RSS readers can be quite practical for staying up-to-date on various topics. Next, AI-powered apps capable of leveraging OpenAI or OpenRouter APIs can also be quite impressive, such as OpenCat on iOS. Moreover, scientific proxy tools can be incredibly useful for those who need to access certain online resources. Finally, I'd be thrilled to hear about other apps that people find particularly useful or enjoyable.
