GeyserLog 2.2.2 should now be available in the Apple App Store.
This release is mostly bug and crash fixes and display improvements.
Added Activity Notifications. These are not Push Notifications, but if the app notices a new event for features for which you've selected notification, it will pop up an alert. (That way an eruption of Fan & Mortar won't get lost in the noise, for example.)
Added Reload Recent Activity, which will download of all activities for a feature over a given time span (from 1 day to 2 years). It's a way to download past activity for features which don't erupt much. (I take no responsibility for what happens if you do something like try to download 2 years of Old Faithful eruptions. Other than suggest you delete the app and reinstall it...)
