The program is designed to notify the user about the approach to the chosen station of the Moscow metro.

ATTENTION: at the moment the program works only with smartphones with active SIM-cards of operators: MTS, MGTS, Beeline, Megafon and Tele2. Also, neither the developer nor the product guarantees timely notification of the user. So far, the program works most stable on smartphones with a SIM card from MTS and MGTS operators.

When you open the program for the first time, you need an internet connection to download the database of metro stations.
After loading the database, all currently available stations of the Moscow Metro and the MCC become available for selection. The user needs to select the station at which he wants to get off. After selection, a new window appears, where when you press the "START" button, a service will be launched in the background, which, at the moment of approaching the station, will notify the user with a sound and (or) vibration signal, depending on the current sound profile in the smartphone. The service requires GPS to be enabled. Don't forget to turn off GPS after using the app to save your smartphone's battery.
