Updated: The app has disappeared from the App Store. The reasons are not specified.
The developer of the Calendar 2 application added code for mining the Monero cryptocurrency to it. The miner is turned on by default as a way to pay for premium functions: cryptocurrency mining is in the background. Ars Technica Edition drew attention to an unusual update .
Calendar 2 is the first time that a mining script is found in an application from the App Store. The store is characterized by strict moderation of programs.
When Calendar 2 is launched for the first time, users are warned that the application will start mining cryptocurrency in the background in exchange for premium features. However, mining can be completely disabled in the settings or pay for advanced access with money.
Ars Technica wrote about the situation at Apple, but didn’t receive an email response in a day. At the time of publication of the note, the application is still available for download.
According to the author of the program, the miner was added for the sake of experiment, to give users the opportunity to try a new way to get all the features. However, errors were found in the release version of the application: one led to the fact that the miner did not turn off, despite the choice of users, and the other loaded the processor at 100% capacity instead of the planned 10-20%.
The developers are already working on a new version of the program and promised that they will remove the miner from it. They substantiated their decision with several reasons, including the fact that they will not be able to quickly fix bugs that cause the processor to load.
Apple guidelines do not contain prohibitions on the introduction of miners, but the rules describe that “applications should not quickly consume battery, overheat the computer or cause unnecessary load on the device’s resources”.
