A smartphone can do much more than handle calls, messages, and social media. With the right apps, it can become a surprisingly capable productivity tool. My old Pixel 6a is part of my daily routine, but the apps installed on it make it a really productive gadget. Over time, I've discovered several useful alternatives to the default Android apps, each solving a different everyday problem. From managing information to transferring files and browsing the web, these six apps have earned a permanent place on my phone.
