1. Tomato Potato app

The Tomato Potato app allows you to plan, manage, execute and record your work in a simple and intuitive way.

The core of the app is the combination of Tomato Work and to do list, which allows you to plan your tasks and complete them one by one with Tomato Work.

As a free program with basic functionality, it's more than enough to meet your daily needs.

But advanced features like sub-tasks and goal management are available for a fee. If you need it, you can buy it and experience it.

2. Forset

Forest is a tomato-based software that allows you to stay away from your phone for a while and focus on your current work.

It can be used as a timer, and you can also monitor yourself on your phone.

Whenever you wish to have a period of focused work, you can plant a seed in Forest.

Over the next thirty minutes, this seed will slowly grow into a large tree. If you can't resist the temptation to leave this Forest to look at Twitter or play games during this time, the vibrant, cute little tree will wither and die.

If you are dedicated enough, then you can build your own Forest. You can even buy different trees with the gold coins you get from your concentration, making it an easy and efficient program indeed.

3. Tide

Tide is a simple tomato clock app that doesn't support complex usage like Todo List, GTD, etc., except for customizing the length of the tomato clock. Just tap "Start Focus" to start the timer.

But Tide creatively combines the feature of white noise with Tomato Clock. The app has built-in white noise for 5 different scenes: ocean waves, rain, forest, meditation, and café, and it also offers a music fusion mode, so that even if music is playing in the background, the white noise will continue to play. You can turn on the cafe white noise, pick a relaxing song list and simulate the feeling of being in a cafe.

For those who can't keep their hands off the phone, the 'Immersion Mode' feature can come to the rescue, as long as you exit the app to the background, after a few seconds, it will result in the failure of the current round of timer, which makes it so that you can't fiddle with your phone during the timer, and you can only focus on your work.
