Started out ok, but never got updated for newer devices. Still stuck in iOS 6. Most content is now inaccessible and behind an organizational subscription paywall. Charging money for public domain Landsat imagery, stay classy ESRI. App still has low-quality basemaps with bad labeling that are obvious reprojections and are not native to EPSG:3857. In short: aging, mediocre, and expensive.
