With rapid technology advancements and increased usage of handheld devices such as smartphones, tablets, and smartwatches, people's reliance on these devices has grown beyond their utility as a means to communicate. Today, these devices are also helping people make healthier lifestyle choices regarding nutrition through different dietary applications, thereby saving expensive visits to doctors and nutritionists. These applications provide awareness about nutritional habits and keep track of a person's physical activity for planning their dietary needs. However, the selection or development of the dietary application for catering individual needs, and implementing successful interventions toward behavioral change is a challenging process. Therefore, the following research exercise aims to review existing nutritional applications at length to highlight key features and problems that enhance or undermine an application's usability and build the case for a generalized implementation that can cater to most people's needs. The findings from this analysis will help to inform the future development of more effective mobile apps. Furthermore, it will also help develop standard guidelines by keeping in view dietician's and researcher's perspective.
