This kind of content seems more appropriate for WebMD or WikiHow than the NYT website.<p>There&#x27;s no discussion of any substance here, it&#x27;s pure filler. Differences in meditation technique and course format between apps find no mention, and there&#x27;s no evidence provided showing that any of these apps is an effective aid to meditation. Most considerations on the list are applicable to an app focused on just about any positive habit people might want to incorporate into their daily lives.
