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.

About

Turn “you snore” into a thoughtful next step. Lullaby Sleep helps couples collect a few nights of private evidence, review what happened together, and decide what to do next. It focuses on useful observations—not a sleep score. MONITOR ON YOUR TERMS Start a session only after everyone in the room agrees. Lullaby estimates probable snoring periods while the iPhone is placed near the bed. REVIEW THE NIGHT TOGETHER See recording coverage and a simple timeline of probable snoring periods. Add morning check-ins from the person who may snore and their bed partner to capture both perspectives. TAKE A SENSIBLE NEXT STEP After a few usable nights, Lullaby can suggest collecting clearer evidence, trying one low-risk change at a time, or discussing observations with a clinician. PRIVATE BY DESIGN • Sound classification happens on the iPhone • No account, cloud upload, advertising SDK, or tracking • No raw full-night audio is retained • Session markers, check-ins, and preferences stay in local app storage • Delete all local data whenever you choose BUILT WITH SAFETY IN MIND Lullaby Sleep includes shared-room consent reminders and clear guidance for symptoms that deserve professional attention. Lullaby Sleep is an informational wellness tool. It does not detect or diagnose sleep apnea or any other medical condition. Results can be affected by bedroom noise, another sleeper, device placement, and interruptions. Formal clinical testing is required for diagnosis. If someone is dangerously sleepy, avoid driving or safety-critical work and seek medical advice.
