Smiling Mind is a non-profit organization based out of Australia that offers a free meditation app. While Smiling Mind's primary goal is to get mindfulness training into the Australian National Curriculum by 2020, the organization is working hard to spread the app and its benefits to as many people as possible, helping to raise awareness for the power of mindfulness.
What separates Smiling Mind's meditation app from others available is the amount of specialization it offers. Many meditation apps offer a variety of different programs, leaving the user to decide what's best for them. Smiling Mind incorporates research from UCLA, Harvard, Oxford, Johns Hopkins, and others to craft targeted, apt well-being systems. The personal well-being modules run specific age ranges, and the app also has separate modules for groups (e.g. the classroom, the workplace, or sports teams.)
