This 12-week study aims to test a sustainable incentive-based physical activity app program that may lower the size of incentive needed to stimulate physical activity and drive incentive costs down. After registration, users were instructed to (a) enable step count tracking and (b) 'carry their phone' as much as possible over a five-day baseline period. Days with step counts between 1,000 and 40,000 were considered 'valid days'. Users first personalized daily step goal was calculated using the median step count of the five-day baseline. A goal was given once five days of step data were collected; if the median was \<2500 steps per day, the first goal was 2500 steps. Afterwards, step count goals were reassessed weekly and new step goals (past 30-day median) were introduced to the user on Sunday night (utilizing the "fresh start" effect). There was no increase on top of the median (e.g., +500 steps/day) to promote activity consistency and reduce the number of days with step counts lower than the 30-day median. After the baseline period, participants earned FIs in the form of 'points' ($0.10 USD per day) for reaching personalized daily step goals. Since people tend to overvalue points ("numerosity" concept), this is valuable to make smaller FIs more effective. Points could be redeemed for movie tickets and gym passes. Users could opt-in and participate in a weekly step goal challenge (i.e., complete 5/7 daily goals) for points ($0.25 USD). For the first 12 weeks, users could complete \~2-4 health knowledge questionnaires or surveys per week, for points (\~$0.25 USD per quiz); this served as an educational feature. After Week 12, health knowledge questionnaire frequency drops to once a week. Users could earn a maximum of $23.65 within the 12 weeks. The health knowledge questionnaires primarily covered healthy eating and meeting PA guidelines (in line with the National Health Service (NHS), "Live Well" guidelines).
