After looking at a book, document, or screen for a long time, your eyes and head can feel tired before your focus is ready to continue. Doply is a short transition app for that moment. After a focus timer ends, or before you start again, you can follow a moving dot for 30 seconds to 1 minute and give your eyes a brief pause. This short transition is inspired by papers and research on visual comfort and attention design. - Color and emotion research on how hue, brightness, and saturation may influence emotional tone and arousal - Curvature preference research on how rounded forms can feel more comfortable than sharp shapes - Smooth pursuit research on how following a moving target requires attention, and why speed and movement range matter - Accessibility research and practice around motion comfort You do not need to choose a meditation course or start a long session. Doply focuses on one timer and one visual point to help you settle scattered focus after using your eyes for a while. Use Doply when: - You finish a 25-minute focus timer and want a short pause before the next task - Your eyes feel tired after studying, reading, working, or looking at a screen - You want to pause briefly without opening a full meditation app - You want a quiet transition routine without scores or records - You want to adjust speed, motion style, and reset length yourself Key features: - 25-minute focus timer - Short break and long break timers - 30 sec, 1 min, and 90 sec visual resets - Sweep, Orbit, Eight, Pulse, Still, and Stereo reset modes - Adjustable motion speed and reset length - Optional local stereo cue Doply is a wellness tool for everyday focus and short transitions.
