### 2/5 — Where is the graph?

*2021-10-26, version 2.2*

If this app saves the data it detected, will someone tell me where it is?

### 3/5 — Advanced features

*2022-10-02, version 2.2*

Hello, I am wondering if you could develop a couple of features that could be added to this app since it seems very useful. One is the ability to control the scrolling speed. The second would be very important for someone testing rpm of a engine such as a chainsaw. That feature would be the ability to convert the one of the axes of movement into RPMs which is revolutions per minute to test the speed of a chainsaw engine. Thank you.

### 4/5 — Cool, could have more

*2020-03-29, version 2.1*

There are many features that I would make this 5 stars. 

The ability to control the speed at which the seismograph moves, therefore the frequency of the recordings.You should be able to save data after running a recording. I think magnitude equivalents should be added, and triggers for when the shaking surpasses a set magnitude. Other than that, this app is perfect.

### 5/5 — Is gud.

*2022-10-03, version 2.2*

Is gud fun.

### 5/5 — See minor vibrations getting to Tube HiFi Amp

*2022-04-26*

Simple & easy to use. Great App thank you!

### 5/5 — Quality app

*2020-11-11, version 2.1*

3 axes, each axis displayed separately, sensitivity control, simple user interface, and no ads so far.....

### 5/5 — Just what I needed

*2019-02-06, version 2.1*

This was the perfect app for my use.  All I wanted was something to show relative vibrations while I was testing a piece of equipment.  Didn’t need data storage or some sort of precise numbers.  This fills the bill perfectly and no ads, no bothering me about buying another app or purchasing additional functions.  If you’re looking for just what it does it is well worth your time to check it out.

### 5/5 — Best seismometer app!

*2015-03-28, version 1.1*

Free, no ads, sensitivity, colours, it's amazing!
