УЭШКА is a mobile application designed for subscribers of the "Universal Electronic School Card" (UESC) system. It allows users to receive notifications in real-time about their child's attendance, academic performance, and school meals. The selection of notifications depends on the user's chosen tariff plan.

The app offers several options, including a mobile version of the subscriber's personal account, which allows users to monitor their child's school card account balance, including their meal balance, and change their tariff plan. Additionally, users can receive notifications about their child's attendance, including time of entry and exit, as well as notifications about their academic progress if the school has an electronic diary and journal module. Finally, users can receive notifications about their child's school meals and expenses in the school cafeteria if the school has a "school meals" module.
