SnapAppy is a positive psychology intervention promoting positive thinking by integrating momentary smartphone photography with traditional intervention methodologies to improve emotional well-being.
Over a month-long study, participants were required to take photos and write about positive moments, past events, acts of kindness and gratuitous situations whilst also logging their mood and affect using established psychological measures.
The results indicated that features such as the number of photos taken, the effort applied to annotating the photos, the number of photos revisited and the photos containing people were positively correlated with an improvement in mood and affect.
