Мой ЗСД is an unofficial mobile application for the paid West Speed Diameter (Западный Скоростной Диаметр) highway, available on Android. This app offers complete control over your contracts, even if there are multiple ones. It includes a widget for each contract, pop-up notifications for low balance, and payment through the official website. The app provides only essential features, making it easy to use.

Compared to the official app, Мой ЗСД has several advantages. It allows adding an unlimited number of contracts and widgets on the home screen for each contract. The app provides background checks instead of push notifications, ensuring that notifications always arrive. Additionally, the authorization does not fail, and users can view transactions for each contract. The app also offers more intuitive control over tariff options. However, the app's design is simple and lacks visual appeal.

To use the app, you need to obtain login credentials from the official website of West Speed Diameter, accessible through the Personal Account section. The payment process is secure, as it takes place through an encrypted (HTTPS) connection on the official website of West Speed Diameter.
