Although user reviews generally showed positive opinions and ratings of the apps, developers should pay more attention to users’ technical problems and inform users about expected payments, along with their refund and cancellation policies, to increase user loyalty. Negative ratings were associated with trigrams related to adding new foods, technical issues, and app charges.Ĭonclusions: Motivating users to use an app over time could help them better achieve their nutrition goals. Usability and functionality (tracking options) of apps were rated positively on average. We identified the positive and negative topic trigrams (3-word combinations) among the most frequently mentioned topics. Negatively rated topics mostly referred to app charges and technical difficulties encountered. Most topics referred to the positive evaluation of the apps and their functions. Most of the users providing feedback were generally satisfied with the apps they use (average rating of 4.4 out of 5 for the 15 apps). Results: Using the topic modeling technique, 11 separate topics were extracted from the pool of user reviews.

After a series of text processing operations, two text-mining techniques (topic modeling and topical n-grams) were applied to the corpus of user reviews of diet-tracking apps. Methods: We collected 72,084 user reviews from Google Play Store for 15 diet-tracking apps that allow users to track and count calories. Identifying the topics that users frequently mention in their reviews of these apps, along with the user ratings for each of these apps, allowed us to identify areas where further improvement of the apps could facilitate app use, and support users’ weight loss and intake management efforts. Objective: The aim of this study was to identify the key topics and issues that users highlight in their reviews of diet-tracking apps on Google Play Store. To foster motivation for long-term use and to achieve goals, it is necessary to better understand users’ opinions and needs for dietary self-monitoring. Ease of access and user friendliness make diet-tracking apps an important ally in their users’ efforts to lose and manage weight.
