The app can be downloaded here, and has been fully tested and works OK with Mac iOS X. In order
to install the app, you will need to double click the Q2.pkg. You will get a
message telling you that the app is not from an identified developer. Go to
Settings/Security&Privacy and click the “Open anyway” option. The app will
then install. After installation when you run the app, the iOS will flag that it needs Java 6E platform in which to run. If you click the more option
you will be taken to this page to download the legacy version of Java
that you need.
Once you install the deprecated version of Java the app will run normally.
