Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

The goal of this study is to learn whether a personalized mobile app can help adults exercise more. The in-house developed app, called iMovin', works with a wireless activity tracker worn on the wrist. The main questions it aims to answer are: Does a personalized version of iMovin' (with features matched to a person's exercise motivations) increase physical activity more than a standard, non-personalized version? Does using iMovin' change how people are motivated to exercise (for example, moving from doing it because they feel forced to, toward doing it because they genuinely want to)? Researchers will compare a personalized version of iMovin' to a non-personalized version (with all features turned on for everyone) to see which one works better at increasing physical activity. At the start, participants will answer a questionnaire about their exercise habits and motivations. Based on their answers, they will be grouped by motivation type and then randomly assigned to either the personalized app or the non-personalized app. Participants will: * Wear a wireless activity tracker every day (except while showering, sleeping, or charging it) for the length of the study * Use the iMovin' app on their phone, which syncs with the tracker to record daily activity * Log at least 100 steps of activity per day * Complete follow-up questionnaires about their exercise behavior and motivation * Attend a first session to sign up, get a tracker, and complete a baseline questionnaire, and a final session to return the tracker, complete a last questionnaire, and be debriefed The study ran in two phases. Phase One was a 1-month pilot study conducted at the NUS School of Computing. Phase Two was a longer, 24-week trial conducted at multiple locations around NUS, with participants also completing shorter questionnaires about their exercise motivation every 30 days.
