Tick Tick

Productivity

Android

TickTick isn't as popular as other to-do list apps. However, it may be the best one. It covers the basics like recurring tasks, reminders, push notifications, various organizational features, and categories. The app also lets you share tasks and entire categories with other people. This makes it great for family use, small teams at work, or other such groups. It's also setup in such a way that stuff like grocery lists are easy to do. All of the good stuff comes in the free version. The premium version is mostly for heavier business and enterprise use.
