IBM has released on Apple App Store the new Connections 6.0.0 app and looks great !!!
Connections 6.0 is totally redesigned and offer a new user interface with application links on the bottom with customizable UI and options.
To have an idea of the new UI check the following screenshot taken from the App Store page.
To be able to run this app on iPhone, iPad and iPod touch iOS 9.2 or later is required.
Right now in Italy I Cannot find Connections 6.0 on Google Play Store but I can suppose the Android release will come soon too.
This morning I tried the app with a Connections cloud account and with an IBM Connecitons 5.5 CR3 on prem and worked fine for both environments so, please don't hesitate and go to check your App Store because IBM has made a great work !
Update: Android distribution has started too, according to this blog post made by Andreas Ponte
