Yes, you can meditate with Core even if you don’t have a Premium subscription.
Premium subscribers get access to hundreds of instructor-guided meditations, the vast majority of our library. More sessions are released every week, so this library is constantly growing, so you can take a brand-new meditation class almost every day.
Non-subscribers will have access to a smaller library (~40) of meditations. This includes a basic set of Guided meditations, as well as unguided Breath Training and Sound & Music tracks, so you can maintain a consistent meditation practice even if you decide not to subscribe.
If you’re using Core without a subscription and decide you want to upgrade, you can do so at any time from within the app, via the App Store (for iOS users) or the Google Play Store (for Android users.)
