The Rocket

Great App!
If you want earthquake data- this is the App you want!

Add this please

This is a nice app but what it really needs is the ability to utilize the iPhone accelerometer to detect earthquakes and automatically share that data to the cloud and/or the USGS.

Only when enough similar readings are detected from a certain region within a narrow timeframe would the data be considered legitimate and then be pushed back out to the map for all users to view.

The app could also be active only at certain times of the day/night that the user defines. As well as only be active when connected to pre-defined wifi networks. Such as Home or work.

Another option would be to only take accelerometer reading when it is plugged into power (such as when on your night stand or connected to a computer USB).

The app could also use the iPhone GPS to disable sensor reading when moving. As well as only record seismic data when the app detects the iPhone is laying flat on its back.

Another option would be to disable the seismic sensor data output when a face is detected with the front facing camera.

Requiring the app to be running in the foreground would also further prevent false readings.

This could easily, quickly, and cheaply create a huge network of seismographs around the world.

Good

Works well besides the occasional downloading data crash and iOS8 landscape bug at startup.

Five stars because this app isn't rigged with ads - most other programmers could learn something here.

Simpatica

Anche se sarebbe utile aggiungere delle note ai vari posti su dov'è successa la scossa. E magari una piccola intro su cos'è il terremoto, il magnitudo...

Simple and straightforward.

I used it for 5 years and I am glad now it works for ios7!
