Mindtrainr-X app for iPhone and iPad

This App implements a research tool for a nutrition study. It is intended to evaluate its efficacy to promote healthier eating and weight loss in controlled experimental conditions.

The standard procedure of this iPhone tool involves the presentation of two food images, which may be of healthy or unhealthy food. Two dots replace one of the images. Participants must indicate, as quickly and accurately as possible, which way the two dots are oriented.

This App supports research studies in either a centralized research lab or in a geographically dispersed arrangement. Participants in the study can conduct the required sessions under the supervision of researchers at their lab or at home or work. 

The App supports the remote upload of non-personal identifying data to the researchers for analysis.

The App supports multiple users on a single device or one device per user. The ability to support multiple users in a research lab setting can significantly reduce the cost of a study.
