Secret of Happiness

This simple app has one feature; it prompts users to enter 3 things they are grateful for each morning and evening. Notifications can be set for reminders in the morning and evening and can be customized to a time that suits the user. In the morning, users are also asked to enter one thing they hope to accomplish that day, and in the evening to enter one thing that happened in the last 24 hours which they are happy about. The app promotes a ‘30 day challenge’ to encourage users to follow this practice for a month.

Research on the product

Of the range of positive psychological interventions considered to improve key markers of mental health, gratitude interventions are among the most established (Parks& Schueller, 2014). Gratitude journals involve documenting things during the day that a person is thankful or grateful for (for example, three per day). In a randomized controlled trial of 192 participants (67% female, mean age 27 years), participants completing a gratitude journal three times per week showed improved affect at one month compared to controls (O’Connell, O’Shea, & Gallagher, 2017).
