Patook LLC announces Patook 1.4, an update to its popular social networking app for iOS and Android devices. Patook is a unique user-friendly app that focuses on matching singles and couples for strictly platonic friendships. It uses an innovative system to identify messages that are considered flirty or inappropriate. Whenever a user attempts to send such a message, they are notified that it will not be delivered. Version 1.4 fixes some very minor bugs. Patook is Free and can be downloaded from iTunes.
