GeyserLog

Display the latest geyser eruption data as collected by the GeyserTimes.org database.

There are a number of tabs available: “Favorites”, where the user can select which features to watch. “Recent”, the latest activity for each feature, with the most recent at the top. "Timeline", showing the latest reported activity. "Features", where showing every geyser and hot spring in the database. "Logbook", a way to see all of a features activity. "Stopwatch" allows registered users to enter eruptions or notes into the database.

Registered users can also use the app to edit their entries in the database. These will also show up in a "Submissions" tab.

Optionally, predictions, when available, can be displayed for certain geysers. Notifications for window opening times can also be added. Notifications can also be requested for the eruptions of specific geysers, although this does not use Push Notifications and so isn't always timely.

There's also a "GeyserLog-Today" widget, which will show the favorites, even when locked.

Dark Mode is also supported on iOS 13, and a red tinted "Night Mode" is still available.
