GeyserTimes is a top-notch application offering the most extensive collection of geyser eruption and observation data available online. Sourced from geyser enthusiasts, historical logbooks, and researchers' monitoring equipment, this open database aims to enhance our understanding and appreciation of these natural wonders. With the GeyserTimes app, users can access a copy of the online database offline, delve into daily geyser activity through intuitive summary and timeline views, plan basin visits around National Park Service and GeyserTimes predictions, watch the Old Faithful live webcam, and even contribute their own observations and notes for field sharing, even in offline mode.

Please note that synchronization requires an active data connection and manual execution before venturing into the basins. While predictions serve as valuable guides, it's essential to remember that geyser activity is natural and reports may not always be entirely precise.
