Measure everything that vibrates, shakes or moves. Or why not an actual earthquake?

Seismometer uses your iPhone's built in accelerometer to measure movements in two axes, calculate the resulting energy and draw the results on a rolling logarithmic scale.

Customer Reviews

Very poor implementation.

I know there are only two other reviews that give high praise, but one must be from the developer. This seismometer only displays one axis at a time…. a bit useless if you a trying to record all 3 or even just two for that matter. The streaming feature SEEMS to work well…. except it only displays the Z axis even if you select the Y or X axis. It will ONLY stream the Z axis. Since earthquakes and other shaking rarely occur on a single axis, and most are rarely on the Z axis (up/down), this is completely useless.

Allow displaying/recording of multiple axis, and allow the stream to display ANY other axis besides the Z axis, and it will be a GREAT app.

Will pay more up to $ 5.00 easy If ???

Would like to have X Y Z on different pens.

Also to have numbers on the chart.

One more request have a adjustable limit marker and if reading is detected
Above set limit optional audio alert.

Other then this wish list the app is great .

Yes, this is exactly what I would do and want.

This app has the best animated PIN draw then all the rest available.


Outstanding app. The streaming feature works incredibly well. Support by the developer is excellent also.
