While mobile diet, fitness, and weight apps have become increasingly popular, more research is needed to assess their quality beyond ratings and reviews in app stores.

Research shows about half of mobile users (45.7%) stop utilizing apps due to hard-to-use features, and some users abandon apps because they lack desired features.
