### 2/5 — Useful, but…

*2025-04-14*

…can’t stop the screen from constantly moving. If you select a spot the screen moves a little. If deselect or choose another spot the screen moves even more. It’s like playing a video game of whackamole.

### 2/5 — Limited

*2022-11-29*

Very limited info on this app as compared to other apps. No way to fine tune it. A little difficult or glitchy like when rotating and zooming. Only works in landscape mode, unnecessarily. Wrong name for at least one country. 
Only feature I like is the globe representation. 
Sorry 2 stars.

### 5/5 — Great app for quick follow-up on quakes and tremors around the globe!

*2019-08-07*

The color-coded map pins indicating locations of quakes are easy to use and distinguish !when looking at the globe. Zoom in and zoom out works great. Locating large quakes is easy with the color coding. Identify areas of recent seismic activity is easy. The app loads quickly and the developer is responsive to bug reports! Thanks. Great app!

### 5/5 — Earthquake

Great app

### 5/5 — Great app

This is by far the best and most informative app to watch earth movement.

### 5/5 — Quick easy

*2019-06-15*

Love this app! It’s Fast no Bs!  I just wish it had a notification option.

### 5/5 — Observer

*2017-07-19*

Informative world wide..... and EASY to use!

### 5/5 — Best graphical earthquake app

*2016-07-10*

This application is easy to use and provides the best global graphical interface of any of the earthquake applications. It also allows you to easily toggle to check on earthquakes daily or even hourly. Perhaps the application title should be altered so that it comes up in a search of earthquake apps in the app store. Amazingly, this app is totally free and has no ads. Hopefully the developer will update this app to work with iOS 10 when it comes out. Thank you to the developer for providing such a nice app that is totally free.

### 5/5 — Awesome!

*2015-09-22*

Great app, simple to use and updated. Thanks

### 1/5 — Not working

*2015-06-14, version 2.4*

I have an iPod touch fifth generation and none of the earthquake icons load.... It's just an empty map
