Works great
I bought the Striiv Touch and the device connected seamlessly with this app on my iPhone 6 Plus first time. I entered all the settings on the app, linked via the app to RunKeeper, one of its partner apps and went for a long walk. Along the way, the Striiv Touch showed notifications, played the music on my iPhone and just worked well. When I arrived home it synced perfectly with the app and all my updated info was where it should be. Cant find any faults with it so far.
