If your app freezes, simply kill and restart the iPlum app. If you are already logged in you would see the home page in the app, otherwise login as required.
Note: To kill the app without deleting it on an iPhone or iPad, simply double click the home button, locate the running app and swipe it upwards. For ending the app on an Android device, press on the home key until the screens for the running apps are shown. Then swipe the app screen to the right to end the app.
Thanks, your iPlum app download link is on its way!
