til https://en.wikipedia.org/wiki/Headspace_(guided_meditation_platform) >In April 2016, Headspace claimed to have over 6 million people using the app. >Headspace's business model is mainly built on subscriptions: $12.99/month when billed monthly or $7.92/month when billed yearly. Alternatively, a lifetime license can be bought for a one-time fee of $399.99. >Content in version 2 of the app is clustered into four areas once users have completed the Foundation stage - health, performance, relationships and Headspace Pro.[17] The app's interface shows different levels of meditation and employs gamification. Users are asked to complete and master a level of meditation before they can move on to the more advanced section. Each session is about ten minutes long, usually in a video format. Понятно, что дело не в умножении двух величин, а скорее прост забавно, что взлетело. Также все эти уровни заявленные в wiki.
