We were covered in "The Independent Guide To The iPhone 3Gs" By Nik Rawlinson. Here is his review

"This is a novelty app but one that also helps you learn something new. The concept is simple. You just leave tour iPhone on hard surface with the app fired up then tap somewhere nearby and watch what happens.

It looks like something you’d find in a hospital, but it’s one of those things that is very captivating once you’ve looked at it once. In fact, we completely lost track of time when we played with this app as we tried out different tap-based compositions – MTV had nothing on us during this review.

You’ve got the ability to pause the ‘recording’ of movement around the iPhone, in addition to looking at colorful spectrum graph of what occurred in the three seconds prior to requesting that data.

We didn’t quite understand what the chart was showing us. But it looked pretty nonetheless and it’ll make you look über intelligent to anyone looking over your shoulder .

The app will monitor movement for 10 seconds and report back on the last three seconds of activity. You can then upload that data in snazzy graph format to the web for all to see. Old friends will probably think you’ve changed career."

Needs more features

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.

Needs to be able to run in background (Multitasking).

Needs to record magnetometer data as well.

Good free app!

I love this app! However, there are several improvements that could be made. First, the X, Y, and Z lines should be different colors to avoid confusion. Also, all the buttons crowding the bottom of the screen should be merged into a single button called “Menu,” which would bring up a pane with those tabs. And the features should be explained more, I still have no idea what the last 3 seconds screen does. Anyway, great work! I look forward to future updates.

Great but needs some work...

The application is excellent and is one of the few great apps that allow you to export information over UDP with low-pass filtering. However it has two fatal flaws. The first being that it crashes back to the main screen after running for about 24 hours. I’m writing an earthquake monitoring app for various locations in my house and having to check each iPhone/iPod around the house to make sure they’re still running is a pain. Secondly the app needs to be updated for the iPhone 5 screen size and resolutions. Otherwise I’d give it 5 stars.
