it's a fun little app! would be nice to have sensitivity setting but overall it's neat.
When you tap on the X on the ad, a blank window comes up and it cannot be dismissed or moved. Have to exit the app.

## Most critical reviews (10 lowest-rated)

### 1/5 — It would be better if it could be used on all iPhones

*2019-11-10, version 1.3*

If only this app were to be used on newer iPhones the could use it just like I did on my older iPhone.

### 1/5 — Keine aktuelle App

### 1/5 — No support for iOS 11.

*2018-08-09, version 1.3*

Although working fine on older versions of iOS but not on iOS 11 so I can’t run it on my iPhone 5s. At least it runs on my iPad Retina and old 4th gen iPod. Last update was 7 years ago and support URL is now a 404 error.

### 1/5 — Kein update auf 11

*2017-12-28*

Kein update auf 11

### 1/5 — iOS 11 update ASAP!

*2017-12-12, version 1.3*

iOS 11 update ASAP!

This is a nice app but what it really needs is the ability to utilize the iPhone accelerometer to detect earthquakes and automatically share that data to the cloud and/or the USGS. 

Only when enough similar readings are detected from a certain region within a narrow timeframe would the data be considered legitimate and then be pushed back out to the map for all users to view. 

The app could also be active only at certain times of the day/night that the user defines. As well as only be active when connected to pre-defined wifi networks. Such as Home or work. 

Another option would be to only take accelerometer reading when it is plugged into power (such as when on your night stand or connected to a computer USB). 

The app could also use the iPhone GPS to disable sensor reading when moving. As well as only record seismic data when the app detects the iPhone is laying flat on its back. 

Another option would be to disable the seismic sensor data output when a face is detected with the front facing camera. 

Requiring the app to be running in the foreground would also further prevent false readings. 

This could easily, quickly, and cheaply create a huge network of seismographs around the world.

Needs to be able to run in background (Multitasking). 

Needs to record magnetometer data as well.

### 1/5 — Does not work on iOS 11

*2017-11-23, version 1.3*

Perhaps the developer is taking a potty break instead of writing code?
