"Find Hidden Friends on VK - VK Hidden Friends Search" is an Android app developed by Daniil Pavlenko. It is a social and communication category app that allows users to find hidden friends on VKontakte. The app is available in the full version and uses effective algorithms to search for hidden friends.

Using the app is very simple. Users need to enter the VKontakte user's link, click on the "Search" button, and wait for the app to find the hidden friends. As the app finds hidden friends, they are added to the list. Users can click on the "Show" button to go to the user's page.

It is important to note that VKontakte does not provide open access to hidden friends, and the app searches for them using effective algorithms. While the app does not promise to find all hidden friends, it does try to find most of them.
