I see you have a new mobile client for 4.3.1 but I can't seem to find it in the Apple App Store. Is this a 3rd party app or something you have developed? Can you please provide installation instructions?
I could be wrong here since I am not a Confluence user, but I do not think there is a separate client mobile app for Confluence itself. From what I could read, it is using the standard iOS browser as noted in this url under "web browsers - mobile".

You should not need Mini Confluence anymore as noted by 4.3 new features url. Search for "4. Be productive everywhere with Confluence Mobile"
