Get fast notifications, emergency sirens, and live maps for quakes worldwide. #1 Earthquake app for iPhone and iPad. This app is brought to you by SMS Tsunami Warning, the award-winning earthquake monitoring app since 2011. The app turns your phone into an alert system for earthquakes and tsunamis. It monitors seismic activity worldwide 24/7 and it delivers an alert to your iOS device if conditions are met (magnitude, user’s distance from quake, etc.). Alerts are delivered as push notifications with a loud siren sound. APP FEATURES - Live earthquake map - Beautiful simple design, easy to use - No ads - Data feeds from various sources - Metrical / Imperial measurement systems - earthquake alerts / tsunami alerts - Loud siren sound - Quake data (location, magnitude, depth, distance, population density nearby, etc.) - Great educational tool - Support for the latest iPhone and iPad models. The user interface is simple and easy to use. For a better reading, the map only shows "significant" earthquakes (with magnitude equal to or bigger than 4.5 on the Richter scale) detected globally in the last 24 hours. In the Settings screen, you can set your parameters for receiving the alerts (ie. user’s distance from the quake’s epicenter and magnitude). After the parameters are set, you can enable (or disable) the alarm system in one touch for total peace of mind. The app supports both metric and imperial measurement systems (Kilometers / Miles) to assess distances. Each quake is represented by a marker on the map. Tap on the marker to open the details panel and dig more into the quake's data (depth, population estimates, etc.). The app is directly connected to our web platform, where you can learn more about a specific seismic event or, in general, get access to a vast literature concerning earthquakes and tsunamis (fault lines, features, history, etc.). The app is a great educational tool and it offers a vital alert service, especially to those living by the coastline or in seismic regions. The app is free and it contains NO ads. Push alerts are offered as in-app purchase for tiny $2.99 yearly fee (it may change slightly based on your country).

However, reliability issues (delays/misses), billing and support problems, and bugs undermine trust. Some critics question the value of the subscription. Improving alert reliability and user support would help maximize the app’s potential. ### Pros - Interface is straightforward and free of ads. - Personalized alerts with detailed quake information, including offshore vs inland status. - Affordable pricing and good value for push notifications. - Provides peace of mind for people in quake-prone regions and useful data from global seismic stations. ### Cons - Alerts can be delayed or missed and are not instant in real time. - Billing/subscription issues and poor in-app support (inactive status, renewal glitches). - App stability problems like crashes, login failures, and black screen. - Some users feel the pricing model is tacky or misleading and question the value of paying for safety information. ## Similar extensions and apps - [Earthquake Hub & Alerts](https://chrome-stats.com/d/id6742140357) — 4.40 / 5 - [Earthquake Alert Map](https://chrome-stats.com/d/id1557684602) — 2.00 / 5 - [My Earthquake Alerts Pro](https://chrome-stats.com/d/id975770717) — 4.80 / 5 - [My Earthquake Alerts & Feed](https://chrome-stats.com/d/id975709372) — 4.70 / 5 - [Earthquake - alerts and map](https://chrome-stats.com/d/id632040358) — 4.70 / 5 - [Earthquake Alert: Quake Map](https://chrome-stats.com/d/id6787861418) — 5.00 / 5 - [EarthQuake+](https://chrome-stats.com/d/id1504339927) — 4.60 / 5 - [Earthquake: Tracker & Alerts](https://chrome-stats.com/d/id6754299197) — 4.70 / 5 - [Alerti - Earthquake & Tsunami](https://chrome-stats.com/d/id6769612792) - [EarthquakeHelper](https://chrome-stats.com/d/id6759260971) — 5.00 / 5 - [Earthquake: Alerts & Map](https://chrome-stats.com/d/id372888894) — 4.70 / 5 - [Quakes Pro](https://chrome-stats.com/d/id1291712052) — 4.70 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/id1505203661)
