MIUI firmware from Xiaomi has a multimillion army of fans. It is radically different from the "clean" version of Android and offers much more customization capabilities. In addition, Xiaomi has its own set of standard applications. MIUI can be fully appreciated by owners of Xiaomi smartphones, but now other Android device owners have the opportunity to "touch" this firmware.
Company Xiaomi published in the Google Play branded application Mi Calculator.
Unlike most analogues, it has many additional functions and allows you to calculate a mortgage, has built-in converters of currencies and quantities and much more.
Mi Calculator can be downloaded to almost any Android device. Perhaps in time Xiaomi will publish on Google Play and its other applications. This will allow the company to update its branded services regardless of the version of MIUI. This practice is already used by Google, Samsung, HTC and other companies.
