Unfortunately, an Einthusan mobile app is not available on Apple's App Store, nor is one available on Google's Play Store at the time of writing. That said, there are Einthusan apps on various third-party app stores, but we would strongly advise against downloading any such app as there's a very real risk of it being infected with malware. In light of this, we would recommend simply connecting to your VPN and then firing up your mobile web browser and heading over to the Einthusan website if you want to unblock Einthusan on mobile.
