Russian iPhone users know that the Yandex application has been developed for the iOS system. Now an automatic caller ID has been built into this program. When an iPhone user receives an incoming call, the application automatically connects to the Yandex Directory and looks for the caller’s number there. Now in the base of the "Directory" there are more than 5.9 million numbers of various organizations.

If the user missed an incoming call, then the caller is triggered in this situation. The caller’s number will be added to the missed call history along with the name of the organization found. But the number may not be in the database "Directory". Then the application will try to determine the purpose of the caller, based on the feedback from other users about him. The program will connect a special algorithm to the case, which will find and analyze the feedback about the caller. Recognizes the frequency of his calls, their duration and other parameters. Based on this information, the program will give the user an assumption about who could call him and for what purpose.
