The World Health Organization defines mobile health (mHealth) as a “medical and public health practice supported by mobile devices, such as mobile phones, patient monitoring devices, personal digital assistants, and other wireless devices”. In the last decade, the health sector has seen a substantial rise in the number of mHealth apps, many of which are designed to assist users in weight reduction and diabetes management. In 2016, there were 79,000 apps available in the Health & Fitness category in the Google and Apple stores. However, the implementation of mHealth in oncology is lagging, and there are comparatively few available apps. There is a need for the development of more mHealth apps in oncology settings considering the increasing disease burden and potential clinical benefit.
