It’s the most promising change to Ruby on Rails I’ve been waiting for: the ability to create hybrid-native mobile apps. Hybrid apps are native Android and iOS app wrappers that tightly integrate with a Rails app, hosted somewhere online. They offer full native navigation, while keeping the core functionality and UI at the Ruby on Rails server-side end. The two gem versions needed - Rails 5 and Turbolinks 5 - are not officially out yet, but at Firmhouse we’ve been using the release candidates past few months with much excitement.
