There are an increasing number of healthcare smartphone applications ('apps') available. @entity1791 presents a major healthcare burden. @entity1 are increasingly keen to educate themselves regarding the diagnosis and management of their condition. There is no formal regulation of healthcare apps, including a large number of apps relating to @entity1791 . This review aims to examine the range of apps available, and the prevalence of healthcare professional input. Four international smartphone app stores were searched: Apple's App Store, Google Play (Android), BlackBerry App World and the Windows Phone App store. A total of 42 unique apps were downloaded and analysed. Recorded data included the cost (  / ), publisher information, number of ratings, average rating and any documentation of medical professional involvement. Twenty-one (50  %) apps required payment for download. The mean cost was   3.58 ( 6.04) with range   0.61-  34.90 ( 1.03- 58.87). Thirty-three (79  %) of the 42 apps were designed to be used by @entity1 . Fifteen (36  %) of the 42 apps had clear input from health professionals. Twenty-two apps offered @entity1 information, including dietary advice on lowering @entity460 intake, which is contrary to current evidence-based practice. We conclude that @entity1791 apps have future potential to inform both @entity1 and healthcare professionals on stone management. However, inaccuracies in the recommendations made by some apps can be misleading or even harmful due to a lack of specialist involvement. We recommend improving the usefulness of these apps by seeking a 'quality stamp' from recognised urological organisations and greater clinician involvement in future app development.
