A Qualitative Evaluation of the eaTracker ® Mobile App.

Background: eaTracker ^® is Dietitians of Canada's online nutrition/activity self-monitoring tool accessible via website and mobile app. The purpose of this research was to evaluate the eaTracker ^® mobile app based on user perspectives.
Methods: One-on-one semi-structured interviews were conducted with adult eaTracker ^® mobile app users who had used the app for ≥ 1 week within the past 90 days. Participants ( n = 26; 89% female, 73% 18⁻50 years) were recruited via email. Interview transcripts were coded using first level coding and pattern coding, where first level codes were grouped according to common themes.
Results: Participants mentioned several positive aspects of the mobile app which included: (a) Dashboard displays; (b) backed by dietitians; (c) convenience and ease of use; (d) portion size entry; (e) inclusion of food and physical activity recording; and (f) ability to access more comprehensive information via the eaTracker ^® website. Challenges with the mobile app included: (a) Search feature; (b) limited food database; (c) differences in mobile app versus website; and (d) inability to customize dashboard displayed information. Suggestions were provided to enhance the app.
Conclusion: This evaluation provides useful information to improve the eaTracker ^® mobile app and also for those looking to develop apps to facilitate positive nutrition/physical activity behavior change.
