Loop

Read full description

OPUS Loop is a simple meditation timer and sound player.. No subscription. No account. Set up your presets, build your library, and practice however you want. Forever. **What it is** It's a customizable tool for meditation, deep work, prayer or whatever ritual centers you. Underneath that simplicity, OPUS Loop allows you to build unlimited presets, each with its own soundtrack, bell configuration, background visuals, and reminder schedule. Set them up once. Switch between them with a swipe. They're yours to keep. **What it isn't** It doesn't sell content. It doesn't pretend to improve your life. It's a tool, and tools work best when they stay out of the way. OPUS Loop doesn't teach you how to meditate, but does include a list of free online resources that you can learn from. **Your library, your way** Import guided meditations, mantras, or music from your files or iCloud Drive. Use Apple Music tracks or playlists or use the built-in procedurally generated soundscapes: binaural beats (2Hz, 4Hz, 10Hz, 20Hz), white noise, pink noise, brown noise, dark noise. Or just sit in silence. **Bells and timing** Customizable start, end, and interval bells. **Built for your ecosystem** - Apple Health: Toggle tracking mindful minutes on or off - Apple Watch: start, pause, and track sessions from your wrist - Mind & Body mode: Track your Heart Rate during meditation or any other mindful activity you do, like ecstatic dance or yoga. - Live Activities: session progress on your Lock Screen - iCloud: your library and settings sync across devices. Simply add new sounds to your library in the app's iCloud folder and they'll appear in your Loop library. - Siri Shortcuts: automate your practice **Privacy by design** OPUS Loop does not operate any servers. There is no account to create, no data to upload, no tracking of any kind. Your sessions, your library, your settings stay on your device and in your personal iCloud account. We don't know who you are, and we prefer it that way. **Spiritually inclusive** No philosophy imposed. No tradition assumed. Whether you follow a teacher, a tradition, or your own instinct, OPUS Loop is a container for your practice, not a voice in it. --- Made in Romania by OPUS.

About

Moss

Features
Read full description

There's a kind of meditation app that wants to be part of your life. Moss just wants to get out of the way. Pick a duration. Choose an ambient sound, or silence. Begin. Everything else (session log, streaks, mindful minutes) stays quietly on your device, private and unhurried. Now on Apple Watch, too. Start a session right from your wrist, pick your own duration, and it logs back to your phone automatically. After a session, if you want, leave a quick note on how you felt. Entirely optional, and easy to turn off if it's not for you. No guilt if you miss a day. No badge pressure. Just a still place to return to whenever you're ready to breathe. Moss is for people who already know why they want to meditate. It just makes it easier.
