one sec research

Our peer-reviewed studies show that one sec changes smartphone habits deeply and sustainably.

We have conducted research on the psychological effects of the app demonstrating that one sec reduces app usage by 57% and significantly improves life satisfaction.

Note: one sec does not collect user data by default, only users who opt-in to participate in our studies, and fill out the intro/exit surveys contribute data.
