Design outcomes

Primary

Measure	Time frame
Moderate to vigorous physical activity (MVPA) measured via the self-reported SQUASH questionnaire at T0, T1 and T2 and via ActiGraph accelerometers at T0 and T2	—

Secondary

Measure	Time frame
1. Commitment measured using a scale based on Webb et al. (2005) at T0, T1 and T2 2. Self-efficacy measured based on the self-efficacy for exercise scale at T0, T1 and T2 3. Intention measured based on Sheeran et al. (1999) at T0, T1 and T2 4. Appreciation rates of the mobile elements measured using a self-composed usability and experience questionnaire at T1 5. Appreciation rates of the intervention program including mobile element measured using a self-composed usability and experience questionnaire at T2 6. Participation rates and drop-out rates are measured via questionnaire participation rates (at T0, T1, and T2), accelerometer participation rates (at T0 and T2), Active Plus (at T0, 4 weeks post-baseline, and at T1) and I Move (at T0, 3 weeks post baseline, 6 weeks post-baseline and at T1) participation rates and process data (continuously)	—
