They can then move these senders between white and black lists to either block or allow receiving SMS from the selected sender. The app also has a feature that allows users to view the list of blocked SMS to avoid missing valuable information.

Overall, SMS-фильтр is an easy-to-use and efficient utility app that helps users manage their SMS inbox. The app is free and available for download on the Google Play Store.
