Ad-free, versatile, and focused timing software that helps you concentrate on your work or studies. Introduction: Whenever you want to focus on a task (reading, working, preparing for exams, etc.), you can activate the "Focus Mode," and a "little flying man" will appear on the clock, moving towards your goal. If you can't resist checking your social media or playing games, unfortunately, the "little flying man" will disappear immediately, and the Focus Mode will exit (you can switch to background timing mode)... If you activate the "background timing mode," you can use other applications after setting the time, and the clock will send a reminder notification when the time is up. If you succeed in the challenge, it will be recorded in the daily focus statistics. The longer you study, the darker green the cover background on the statistics page will be. There are also surprises for successful challenges! After activating the background mode, the countdown can be displayed in Lingdong Island!
