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.
