Today we updated Collector for ArcGIS on the iOS platform. This new release introduces some nice new features and a host of UX updates and bug fixes. Please read our official blog announcement from the ArcGIS Blog site for details.
I am the Product Lead for our Field Apps team at Esri. I work with an amazing team building out our field solutions.
Please feel free to ask me anything about ArcGIS Field Maps, Collector, Workforce, Explorer, Navigator, and Tracker.
