Skype users have ridden a rollercoaster of different designs over the years, and the latest version promises yet more change. Version 6.0 has been completely redesigned for both iOS and Android apps, which are now in lockstep with each other. For Google's ecosystem, the new layout took a page from the Android 5 "Material" playbook with circular icons and other touches. Other features include a floating action button to start new calls or chats ( la Facebook's Messenger), enhanced search and improved messaging. There are also custom ringtones, photo sharing and web link reviews to bring the app in line with rival messaging products like Google's Hangouts.
