GeyserTimes is the most comprehensive database of geyser eruption and observation data on the internet. Data comes from geyser-enthusiasts, historical logbooks and researcher's electronic monitoring equipment. All data is open and made available to researchers so that we may all come to understand and appreciate these rare wonders of nature. Use the official GeyserTimes app to: • Browse a copy of the online database without a network connection (defaults to one month worth of data) • Explore the daily geyser activity in intuitive summary and timeline modes • Plan your day in the basin around predictions by the National Park Service and GeyserTimes • Watch the Old Faithful live webcam on your phone or stream it on your TV using AirPlay • Enter your own eruptions and notes to share field observations, even while offline Notes: Synchronization requires a working data connection and should be performed manually before heading out into the basins. Predictions are not 100% accurate as geysers are natural features and the user reports they are based on can be erroneous. ## Key features - Offline database access - Daily geyser activity summary - Geyser eruption predictions - Live geyser webcam - Offline observation logging - Data synchronization ## Recent user reviews (5 of 5) All indexed reviews: https://appshunter.io/ios/app/geysertimes/id1191485823/reviews.md ### 5/5 — Terrific App *2026-03-09* Would like to see notification option for eruptions. Probably through “favoriting” geysers. ### 5/5 — AMAZING!! *2025-04-17* GeyserTimes is a gem! I absolutely love this app and everything it has to offer! ### 5/5 — Amazing app *2023-12-02* I love GT! I only have on wish, please add a little feature maybe on the eruption interval list where you could see the average height for the geyser. I don’t know how much this is doable but it would be nice. Anyway I LOVE GEYSER TIMES. ### 1/5 — Don’t Update To Newest Version!! *2023-04-30* It now shows a blank blue screen & locks up on startup. Just downloaded the new version, and am running it on iPad OS 15.5. Wish I didn’t “upgrade” to the newest version as the previous version worked perfectly, and there’s no way to go back. ### 2/5 — Fails to load properly *2021-06-17* After a certain amount of refreshes the app will cease to reload new times ## Frequently asked questions about GeyserTimes ### What is GeyserTimes?
