## What is Sismo?

Sismo vibration meter is analyzes the data from the iPhone or iPad accelerometer and builds a vibration spectrum. This allows users to see if an earthquake is happening in their area. Measure all vibrations and earthquakes !

How it works

Seismometers are devices used to measure earthquakes. They are also known as seismographs or body tremors. Seismometers are used in seismology to measure the strength and direction of earthquakes.

Sismo uses the iPhone or iPad's accelerometer to detect vibrations in the ground. These vibrations are then analyzed to create a vibration spectrum. This spectrum is then compared to known earthquake waveforms. 

The Sismo iPhone App is the perfect tool for anyone interested in seismology or earthquakes. Sismo is analyzes the data from the iPhone or iPad accelerometer and builds a vibration spectrum. This allows users to see if an sismic activity is happening in their area.

Check the vibrations with your phone!

Sismo is a seismometer that measures the vibration of the Earth. It is used to study earthquakes and tsunamis.One of the most important tools for seismologists is the seismometer, which is used to measure the vibration of the earth caused by earthquakes. The seismometer can also be used to measure the body tremor of people suffering from Parkinson's disease.


Measure vibrations with iPad or iPhone. Always see these vibes with great viewing options.

Customize the application with your own colors with 4 views.

Special Views ;

● OSCILLOSCOPE
The oscilloscope view is arranged for a full hollywood effect and is enjoyable to watch on your iPad or iPhone at your desk.

● METRONOME
Metronome view detects harsh vibrations and has a plain appearance.

● GEYSER
Geyser view also includes an alarm function and will easily show you the smallest movements like a geyser. You can set the threshold of vibrations listening and the threshold at which the Alarm will sound.

● WAVE
The wave appearance can be set as a straight wave or a moving wave, allowing you to measure with high precision.

Many views give you the chance to make a full screen. This allows you to focus on data only. You can also use it as a hollywood effect. People around you will be amazed when they see the cinematic view on your device.

In addition, you can customize the entire appearance through the settings tab, if you are using your device with a stand, you can easily control the tilt of your stand with the bubble level function, which you can access under the settings tab and you can make accurate measurements with a perfectly flat floor.

Cool features! Fun to mess with! Will come in handy when I move to the West Coast!

### 1/5 — App stopped loading on iOS 17

*2023-10-02*

Developer isn’t testing and keeping up with latest iOS. The app fails to launch now. No error or message displayed. Partly and iOS issue I guess.

If you encounter any further problems or have suggestions, please don't hesitate to let us know. Your feedback is valuable to us.

### 5/5 — Beautiful and simple

*2023-02-28*

First of all, I just want to say how refreshing it is to download an app and immediately get value out of it. I needed a simple app to measure vibrations on my desk because it was wobbling a lot. As soon as I opened the app for the first time I saw the oscilloscope running. No ads, no account signup, just a super minimal interface that shows me exactly what I need. I would happily pay $ to support the dev team based on my experience alone. The visuals are also beautiful, I spent way more time than necessary just shaking my phone to see the geyser and metronome move. 

I almost gave four stars due to one annoying quirk: whenever the device is rotated I lose my graph. If I’m in the oscilloscope and rotate to landscape, I have to select my chart type again. It’s also weird to me that the bubble level is hidden in the settings and not a top level view option.

**Developer response:** Thank you for sharing your experience with our app! We're happy to hear that you found it useful and liked the design.

We apologize for the issue with the graph disappearing when you rotate your device. We will work on fixing this in future updates. We also appreciate your suggestion about making the bubble level more visible.

We really appreciate your support and feedback. Your input helps us make the app better. Thank you again!
