Calendar 2Is a calendar application for macOS provided by Qbix, which is an enhanced version of the default calendar application. Calendar 2 had a free version and a premium version for a fee, but in exchange for releasing the premium version of the function, an option to allow mining the virtual currency Monero in the background was added. The premium version seems to be able to choose a continuation plan of $ 17.99 per month (about 2000 yen) or $ 0.99 per month (about 110 yen).


However, Apple said in the App Store guideline 2.4.2, "The application must be designed to use power efficiently, the app can quickly drain the battery, generate excessive heat, Calendar 2 has been deleted from the App Store as a violation of the rule "You should not put an unnecessary burden on you."

Qbix's CEO Greg Maggalchek said that he was asked to re-register the app by deleting the mining option completely after one hour of removing the app to Apple, contacting Apple. Ultimately, it seems that it was decided to offer a premium version free of all functions free of charge for one year to all users who used Calendar 2.


According to Magalshuku CEO, the mining option was valid for three days, while Monero mined during that time was equivalent to 2000 dollars (about 210,000 yen). For reference, since the revenue of the application in the past seven years is 700 thousand dollars (about 74 million yen), the mining option seems to be an attractive method of securing profit for Qbix.
