Convenient app to see current volcanic ash updates – Volcanoes: Map, Alerts & Ash Review

I follow a lot of geophysical activity around the planet. This is a nice app that sends alerts of activity if you want, and has a nice map of worldwide volcanoes and their current activity. some pay for upgrades for hardcore Vulcanist but has enough for my needs on the free version.
