The most basic thing Hive needs is a mobile app called 'Hive'. I've seen people learning about Hive (via Twitter for example) only to get confused, because, and I quote, "I can't find Hive in the app store".
Seems like a mobile app called Hive is the easiest way to onboard people that have gotten vaguely interested in Hive, just want to 'download Hive and learn more about it later'. Because most of us are mobile first, many are going to want to discover Hive through mobile first - and will look for 'Hive' because they don't know about Essency/Dapplr/HiveWallet yet.
From the basic app we can then lead them towards the many other Hive services, for example through gamifying learning about aspects of Hive, or even just via a simple FAQ that says 'this is just a basic app but you're now a member of the Hive ecosystem, here's what that means'.
