After years of using various Android note-taking apps, I’ve simplified my system to three core tools: Google Keep, Google Docs, and smart Android features. Google Keep is the foundation, where I capture quick ideas, while Google Docs handles organizing and writing out those ideas. The two-layer system works seamlessly across devices, making it an ideal solution for both personal and professional note-taking needs.
