Mobile health apps (mHealth apps) are increasingly being used in health treatment. However, few mHealth apps for problem gambling are currently available. In January 2020, the researcher found 17 apps available to Australians from the Google Play and Apple iTunes stores. Most of the apps were free or had low costs. Most of the apps had three or fewer functions. The most common functions were information about problem gambling and blocking software for users to restrict or block access to gambling sites. The apps generally had no or few user reviews. Their download rates varied greatly. The average for the most recent update was more than 12 months ago. This study shows the need for more apps that are professionally designed and based on research evidence and theories.
