About

Study Timer

Read full description

Product Description: This app is a minimalist study tracker for users who want focus instead of feature overload. The interface is deliberately divided into only two sections: - Tracker: A large clock shows exactly how long you have been studying. With a single Play/Pause button, you can start or stop the time tracking instantly. No menus, no distractions, no setup. - Statistics: A visual daily overview shows your study time in blue and your breaks in red. This lets you immediately recognize your actual learning behavior and optimize your concentration phases. Concept: Focus on what matters: The app measures only what counts โ€“ your learning behavior. Ideal for pupils, students, and anyone who wants to study in a structured and measurable way.
