Thank you. When we try to concentrate on something, there are so many distractions. One of the biggest distractions is the smartphone. You need to focus on the book. But I find myself looking at the phone. The plan was to study for 5 hours But you actually spent only 1 hour on the book? Dote Timer is the answer! Let’s start with the special proprietary features of Dote Timer. First, Dote Timer starts only when you flip the device (screen facing down). It will automatically stop when you use or move the phone after activating the timer. Thus, you can concentrate on study or work. Second, you can compare the plan with your actual concentration record. Set up the D-Day of your task. And categorize it into A, B, or C depending on the importance to set up a precise plan. The actual length of concentration is recorded and can be compared with your original plan. Third, the thickness of color denotes how much you concentrated. Thus, you can easily find out the days when you concentrated on your tasks. Especially the app shows in different colors the days of concentration and the days you failed to concentrate throughout the year. So you can compare how you fared yesterday and today to make your day more productive. In addition, collect coins by using the timer and donate them for underserved people. My accumulated time of concentration is converted into coins. When they reach a certain threshold, Dote Planner and Dote Book will be donated to underserved students. There are also the standings of donation, Which motivates the users to compete in the donation of coins. Dote Timer can be set up as desired. Just focus on what you have to do to contribute to society. The most efficient time management app for the perfect time allocation. Download Dote Timer now!
