Seismometer app for iPhone and iPad

Wow, I like this. I tried that on my speaker and on the floor beside to see if there was a lot of vibration transfered from the speakers and the floor. I was impressed with the results. There is only few things I will like to see, if you plan to improve it, its a pause and/or stop button, and also the possibility to take few snap shut that can be review after with if possible some kind of scale number and volume. Continue the great job. Frenchy

I find myself opening this app up whenever Im bored.. I just place it on the floor and start jumping to whatch the needle go crazy. I think its quite amusing.. For people easily amused, this app will take up lots of your time. I love it!

Very good app. To comment to the ones thatvthink the line should be zero once its on a table is wrong. A car passing on the street is enough to shake an iPhone on a table. A dog barking or your breathing on the table while watching the app is enough to move the needle to not equal zero. Very nice tool to show students how environmental vibrations effect items. Try it go to another room and shout if youre loud enough you can move the needle.

The update for this app makes it a winner. A fun little app to toy around with. Recommended! --------- Original concept but does not flatline. Also, cannot seem to duplicate the "Settings" and "Pause" buttons as viewed on the screenshot of this app. This app is almost fun.

A neat and clever gadget that actually works. It will be helpful if the developer provides explanation to the meaning of the various setting components : e.g. What is the difference between having a high-pass filter or not ? What is logarithmic scale versus linear scale ? And what are the distinctions between "Y&Z" and "All" axis? etc. Is there a typical setting that resembles a weather stations seisometer ?

I work as a camera operator for Broadcast TV... Having a stable surface is critical for a shooting position. I can totally see this app as being a valuable tool with some further useability added. With the needle shortened we can now see more data which is better in this version but to scroll back and review your session would still be very valuable to me. The added controls and pause feature are great additions and going in the right direction. Suggestions: add a time count along the graph margin to see how long the session has gone. When paused if you can *scroll* back and review the data this app would add huge useability. As it stands now, you only see whats on the screen at that given moment which is this apps biggest limitation. Future consideration to scroll, save the graph, compare sessions, email graph, and perhaps sound alerts at target thresholds will make this app a truly useful tool rather than just a cool novelty. That said, its still a really cool novelty right now!! Well done. Great job.

Needle quivers even when iPod is on a flat, damped surface. Tried to isolate all vibration (sounds) and still no flat line.

Ok So I Downloaded This And It Seems To Work. Except The Needle Never Stops Moving...... Please Fix It

Jiggles make squiggles. OK cool for 10 seconds. No ability to time/date the track, or explain what is going on. Im a geologist and should find this wonderful but this is a pretty cheesy app.

They make it sound so amazing but u get bored of it in about 4 seconds.

Its way better if its free... And it made my screen go blank and I had to restore my iPod touch.

The 2.0 update removed some useful features from this app. Please bring back the noise filter preference. With the noise filter off in v1.x this app could be used to measure ones own heartbeat, sadly this is no longer possible. Lots of the apps sensitivity is lost in the latest update.
