The app was developed from knowledge gained from the study conducted by Levinson, Stoll, Kindy, Merry, and Davidson (2014) from the Waisman Laboratory for Brain Imaging and Behavior, Center for Investigating Healthy Minds, Psychology Department, University of Wisconsin-Madison on breath counting.
The guidance on mindfulness breathing in this app is accumulated from meditation teachers, such as Sharon Salzberg from Insight Meditation Society and Matthieu Ricard, a French Buddhist Monk.
