The iMTracker is a lifestyle evaluation tool that you can use to determine whether lifestyle factors might be associated with daily outcomes. The iMTracker was developed by physicians in the Individualized Data Analysis Organization of the University of Colorado School of Medicine. This application allows the user to select a given outcome that is causing trouble each day (for example, headaches) and enter data for other possible factors (variables) that might be correlated on that day, or the day before. For example, a person might enter caffeine, meditation, or daily exercise as his or her variables. After a given number of days, the app will provide the user with a score based on the Phi statistic for how strong the correlation might be. At least 3 days of data is required to get a score, although the more data collected, the stronger the association. The iMTracker does not collect or store any data other than what is kept on the users device, and no information about the user is required for use. The PM App Lite is strictly for entertainment uses only, and users should not make any changes in their lifestyle or habits without first consulting their physician. THIS APP IS FOR ENTERTAINMENT PURPOSES ONLY. DO NOT MAKE ANY CHANGES TO YOUR LIFESTYLE WITHOUT CONSULTING YOUR TREATING PROVIDER. The iMTracker is a trademark of the University of Colorado.
