How often is the mobile app updated?

Summary:

Our company uses another external mobile application that we have integrated with Oracle using an External Plugin. Their application receives updates regularly and as a result our businesses use of this app will require frequent sanity/regression testing. So the question has arisen of how often the Oracle Field Service Mobile Application for iOS and Android get's updated? I understand that we get the quarterly upgrades and the Weekly Maintenance Packs - would a prompt for a Mobile App update be linked to either of these? Or are they applied on their own schedule based on security/patches as needed?
