About

Ocean Deep Meditation Timer

Read full description

Ocean Deep is a simple meditation timer. Set a length, settle in, and let a soft bell call you back. That's the whole app โ€” and that's the point. No accounts. No noise. Nothing watching. Just you and the time you keep. WHY "OCEAN DEEP" The mind is like the ocean. Thoughts and feelings rise and fall like waves on the surface โ€” always moving, never still. But underneath, the water is calm, and vast, and clear. That deep is always there. A sit is simply a way to rest in it. A SIT, START TO FINISH โ€ข Set the length โ€” two wheels, hours and minutes, and a Begin. It opens right where you left off, so most sits are a single tap. โ€ข Ease in โ€” an optional warm-up counts down in warm amber. When it reaches zero, your meditation quietly begins. โ€ข Rest in the ring โ€” one calm ring holds the time. Tap anywhere to dim the screen to near-black, set the phone down, and simply sit. โ€ข Well sat โ€” a soft bell marks the end. Save the session, or let it go. No streaks, no scores. QUIET BY DESIGN โ€ข A gentle bell โ€” a soft chime in the app, or a Time-Sensitive notification if you've stepped away. โ€ข Made to be put down โ€” one tap dims the screen so there's no glow to pull at you. โ€ข Apple Health โ€” with your permission, each finished sit is saved as Mindful Minutes. Write-only, never read. โ€ข Look back, gently โ€” a calm record of your practice, this week and every sit before it. A mirror, never a scoreboard. โ€ข Nothing extra โ€” no courses, no library to scroll, not even a settings screen. Open it, sit, close it. PRIVATE BY DESIGN There are no accounts, no servers, and no analytics โ€” nothing to sign up for and nothing watching. Every session lives on your iPhone. The app only ever writes to Apple Health, and never reads your health data. Free, on iPhone and iPad. The quiet is already there. Set a time, and begin.
