Loialcard launches new versions of the app continuously. The frequency may vary over time since certain periods larger new features are developed at the same time since they are interconnected leading to longer release windows.
For a release to be published for you as a client on your App Store accounts, they have to be verified and any additional updates to the agreements have to be signed. Loialcard reminds you as a client about such signings of new agreements. Google rarely updates their agreements and account states, Apple fairly frequently. Guide on how to approve an updated version of the Apple App Store Agreement.
Apart from app releases that are supported by new updates and additions to the administration tool, there are also stand alone updates to the administration tool such as important bug fixes or even major releases of the tool that doesn’t require a new app version. Administration tool releases are not passing through any approval of Apple or Google. Hence, all administration tools are at the same version all the time. Therefore no release ID is used, but rather just a date to reference when the administration tool was updated and with what.
