This browser extension is a life saver. A lot of successful people emphasize the power of focusing on one task. This app greets you and asks you what your main focus is. Each time you open up a new tab, the app pops up and reminds you to stay on track. It replaces the browser tab that is there by default that usually tempts you to go to unproductive websites.

Discover Productive – the app that helps you build positive life-changing habits. Effortlessly track your habits, reach your personal goals, and stay motivated every day.

This is an extension that uses the power of the Pomodoro Technique and gamification. When you start the timer, it will grow a tree from a seed. Your goal is to focus on one task for 25 minutes until the tree is fully grown. It makes productivity more fun. It’s customizable so that you can change the 25 minutes to whatever you want. I recommend the free version because the paid version is unnecessary. It just gives you more pretty trees to choose from and lets you use this on your phone.
