Android App Update (4.0.1)

GeyserTimes for Android 4.0.1

In the past year we’ve primarily worked to improve the stability of the GeyserTimes Android app, migrating to the Realm mobile database which should allow for easier maintenance in the future. However we’ve also managed to add a couple of other enhancements and new features which will be discussed in more detail below.

Updated submit screens

The submit screens have been reorganized to make it easier to enter data. Improvements include direct search for geysers and a new duration timer which should make it easier to submit eruption durations to the database. While we realize you’ll need to get accustomed to the new layout, we believe it is easier to understand and more structured for newcomers who want to contribute data.

Updated entry screens with duration timer for eruptions

The new duration timer can be started by pressing the “Start” button. Once the eruption has finished press the “Pause” button to stop the timer, should the eruption continue (I’m looking at you, Grand) you can press the “Start” button again and the stopwatch will continue. Entries with a running timer can be safely submitted without influencing the stopwatch.

Offline predictions

The GeyserTimes website introduced a new prediction system some time ago that included additional geysers and a more flexible calculation system based on a set of parameters (e.g. add 92 minutes after an Old Faithful long). The Android app has now finally caught up with this development and displays all the predictions using the updated system.

Best of all: it also works offline, which is especially helpful for geysers located in the Lower Geyser Basin. Simply enter a new eruption and the prediction will be recalculated. Echinus, here we come!

Advanced statistics

When viewing the recent geyser activity there now is a “More statistics” button below the calculated interval statistics that will take you to the interval and duration charts, allowing you to analyze the recent geyser behavior at a glance.

Interval and duration charts for in-depth analysis

Just like any other statistics you encounter these should be carefully interpreted though — some geysers have incomplete data or don’t erupt often enough to gain much insight. More often than not, this is more of a fun and intriguing chart than a scientific tool.

Better platform integration

We’ve also improved the overall integration of the app with the Android system. The login, signup and forgot password screens have finally been updated to Material Design, Google’s new design language introduced with Android Lollipop, and web links are now handled by the GeyserTimes app, allowing you to view entries from a web search directly within the app. Most information is now also easily shareable with other apps such as Facebook Messenger and WhatsApp.

App shortcuts have been introduced to allow quicker access to relevant areas within the app (accessed by long-pressing the launcher icon on Android 7.1 Nougat and above). On compatible devices, such as the Samsung Galaxy S and Note series, you’ll also be seeing popups on eruptions and notes that include additional details by hovering over the entry with your finger or pen.

App shortcuts and popups for quicker access to information

Other notable enhancements include the ability to select more than 10 favorite geysers and to selectively filter unwanted geysers in the day summary and timeline (who wants to see all those Old Faithfuls, right?). You can find these options within the application settings.

Your feedback is very important to us, which is why we’ve included a new “Feedback” item in the navigation menu. Don’t hesitate to drop us a few lines and let us know how we’re doing. If you don’t have the app already, download it now on Google Play, it’s free and you won’t regret it.

Thank you for using GeyserTimes and happy gazing,
The GeyserTimes development team

2016 Summer Season Recap

The 2016 Summer season has now come to a close in Yellowstone. We would like to thank everyone for using GeyserTimes. It is because of the people that enter data that makes this project as valuable as it is to the entire community.

Attached is a summary of the data that the community collected during this last summer.

Thanks for making GT what it is today!

Web Update

We’ve been working on enhancements to GeyserTimes, mostly on the electronic data logger side of things, to help with collecting, analyzing and reporting on electronically monitored geysers. These include:

  • A new punchcard to show available data for data loggers.
  • Notes for data loggers
  • Additional admin data logger functions

I’m very excited that there have been two recent permits issued in Yellowstone to study geysers.  I’m proud that GeyserTimes has been identified as a way to help make such data available to the public.

In non-data logger improvements, GeyserTimes now shows flagged eruptions with a flag icon on both the home page and individual geyser pages.

Happy Gazing,


Web Update

We just put some new features on the site tonight!

  • Initial to initial stats
  • Search bar behavior fix
  • Fixed a timezone issue on the data logger charts
  • Fixed some problems with long usernames and their behavior in the header bar
  • Interval display – If two consecutive eruptions are entered in to the second resolution the interval will display seconds
  • Some fixes and additions to the data logger management system
  • Cleaned up some old files
  • Removed v3 of the API. Please use v4.

Prediction Service Down

Just a heads up. The main prediction server ( for GeyserTimes is currently down. The server crashed and Alan has to rebuild the server that provided the predictions. In the meantime we have been working on a new prediction engine that will be hosted on our own server to eventually replace the current server. The new system is not fully ready yet but we have released part of it so we will at least have predictions for Old Faithful. We hope to get the prediction server and/ or the GeyserTimes prediction engine fully operational in the near future.


Android App Update (3.2.2)

Released an update to the Android app that allows for a simple filter to hide all features that are not in Yellowstone from the summary screens. This setting is turned off by default so you will need to manually turn it on if you only want to see features in Yellowstone.

Web Update

Fixed a bug on the sync adapter with the app that entries would not sync under a certain circumstance. Also added a rule to the duration parser so it will not parse any durations that contain a “/” until we get time to correctly handle those durations.
