Learning Tactic is an app created by the developer to fulfill their own need, combining the Pomodoro Technique with the forgetting curve. The Pomodoro Technique is a study method grounded in scientific evidence, allowing for efficient concentration, motivation maintenance, and memory retention. According to Ebbinghaus's forgetting curve, if you don't review what you've learned, you'll forget 80% of it within a month. By reviewing at the right time, you can save study time and effectively transfer knowledge into long-term memory. How to Use: 1. Add a project (study material). 2. Add tasks (study sections) from the task page, accessible by tapping the project image. 3. Tap a task on the home screen to start the Pomodoro timer. 4. End the Pomodoro session once your study is complete. Supports 6 languages: ・English ・Japanese ・French ・Spanish ・Portuguese ・Russian
