With a commitment to giving you the best experience, we have temporarily removed our app from the Google Play store. We're actively working on a version compatible with newer Android operating systems. Although we don't have a specific timeline to share, we want to assure you that we're dedicated to our brand promise of enabling sharing from any device. In the meantime, you can still use screen mirroring on may Android devices with Miracast enabled, using native features like Cast Screen and Smart View.
