Seismograph

It would be great if it didn't record hours of nothing when you're looking for a small disturbance two or three times a day. It needs a way to start recording when vibration is detected. I'm trying to record when vibrations are happening for a few minutes at a time several times a week.

works fine to see and record, except playback won't work

Simple. Easy to use. I downloaded it so I could place it next to my speakers and play music with lots of bass. Very entertaining.

Very responsive. I love the separated axis and customizable GUI. My favorite vibration sensor on the market.

Its a good app to measure earthquake and record also what happend going on .... good job i really like this app .

Awesome for understanding vibration in 3 axis. Variable amplitude display

Recommended ..????

The app is great, very sensitive and accurate. However whenever I try to view recordings the app crashes, making it almost useless to me. I would give 5 stars if that feature functioned.

It is interesting to watch bit fails everytime I try to view the recording. Everytime.

Can we get some sort of alert when the readings reach a certain level?

I like it but each time try to view a recording it force closes.

Crashes when playing recordings on galaxy S5 otherwise great

The app shuts down when I try to view my recordings. I don't have an update available on my phone. I use it to see when my unborn child kicks my phone and I can't show anyone the recording.

Within 60 seconds of installing this I received three unsolicited calls for services. REPORTED TO GOOGLE

It is very fun to play around with. It is also very realistic.

Perfectly shows the movement on all three axis..

Recording playback doesn't work. It would also make the app better if it will still record even when the phone goes idle.

Even on a flat stationary surface, the needle somehow still picks up vibration, this is bad especially when it could throw off some values. The needle shouldn't move at all on a still surface. I like the layout, but cannot trust the numbers. So sorry. I must use Seismo, basic and able to export data still.

It shows vibration awesomely. However if you record and then try to view the recording then app immediately shuts down

I use this app for testing the vibrations induced by motor/propeller on a quadcopter.After exporting the .csv file into Excel graph, can visualize the x,y,z.

It is too much sensitive nice

Add alarm or beeps for alert. Optional. I.e beep if strength is 4 5 6 option.

Useful

App shows any vibration of the phone. In that sense it does what it says. Problem is it can't discriminate between a heartbeat, or an earthquake. But it is good for recording any movement of the phone. May have other practical uses.

Remarkably accurate. Try tapping your device on each side and the top (screen side) and only that sides vibrations move. Good separation of x, y, and z. Really good use of the accelerometer!

Sensitive enough to detect heartbeat with tablet laying on my chest. Very cool, responsive and slick uncluttered display.

Exactly what I wanted.

Its finely working!

Epic

It's a really cool app, I'm excited to see the additional features to come!

I saw where you took the feedback and used it to improve your app. Kudos to you; that's actually why I installed it. I'm glad I did. It does exactly what it's supposed to. Good work, mate.

Really Good, Runs better than most others, should add the ability to log what it detects would make it even better!
