Why does Mobiwol show as if using a VPN connection? This is superficial. We've used technology available to us from within the VPN packaging module offered by Android to be able to gain visibility to your applications' network activities. However, no actual VPN connection is being made, no data is being sent externally by our application, and we do not tamper with the security of your personal data, so you can continue using your apps with peace of mind, and confidence that you will not end up with a higher than usual data bill at the end of the month. Any Limitations? WiFi tethering is not supported with the current version, however can be used simply by turning off the firewall for the period that you wish to use the other feature. We are working on fixing this, so please bare with us.
