There’s no “official” Hive mobile app, as there’s no “Hive Inc.” to launch one! The closest thing right now is eSteem, which is very soon rebranding to eCency. Also, Dapplr is very promising. It just launched on Android and is awaiting App Store approval, so I’m hoping to see it soon!
Thanks for the info. Glad to know it wasn’t just me not being able to find it
