ACS Mobile AppACS is now available as a mobile app for your iPhone or iPad and there is an Android version as well.. If you are on campus, using the ACS app should work just fine - it should detect Austin College's network and IP address range, giving you access to full-text. If you are not on campus, this app does not support proxy authentication at this time; this means that you will need to set up VPN access on your iDevice in order to access the ACS app remotely.
