Doro is a super simple Pomodoro timer that the developer created because personally wanted it. We focused on making the main screen as minimal as possible. To stay true to this concept, we decided not to include any ads. Features: - A Pomodoro timer with 25-minute and 50-minute focus sessions (with 5- and 10-minute breaks, respectively). - Earn 1 fruit for completing a 25-minute session, and 2 fruits for a 50-minute session. - Review the fruits you've collected on the calendar. - Includes background music designed to help you concentrate. - You can customize the colors of the timer and break screens to your liking—change them to your favorite color to boost your motivation. A Fun Extra The name "Doro" comes from Pomodoro, which means "tomato" in Italian. Interestingly, Doro can also mean "gold." If you collect 5 fruits in a day, you'll receive a golden fruit—just a little reward to brighten your day.
