GeyserLog 4+

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.

The iOS "GeyserLog-Today" lock screen widget has been retired. It has been replaced by a Recents widget, Favorites widget and a Predictions widget, which can be displayed in all three sizes.

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

The primary screen allows you to choose four of the more common actions: Stopwatch, Recent Activity, Favorites and GrandWait.

Stopwatch works in sync with the iPhone app stopwatch, allowing you to start, stop and pause, on either device.

Recent Activity shows the latest dozen events posted to GeyserTimes

Favorites shows the latest activity of those features that are shown in the iPhone app's Favorites view.

GrandWait allows you to record events and activity without the need for using your iPhone screen in adverse conditions.

There's also a small watch-face complication which will take you directly to the watch app, while saving the current time as an Observation. A rectangular complication will display the four most recent of your favorites.
