## Pocket Geiger Counter Lite Reviews in United States

### *---- "No"
Nononono
-- 😎 657, 2019-07-27

### *---- "Literally Doo doo"
This app works, but you need to hook it up to a real Geiger Counter in order for it to work! I thought the whole point of the app was to not need an external device! This thing is a big fat pile of doo doo!
-- Kaseii, 2019-01-03

### ***** "Here is your answer as to why it doesn’t work,"
You need to connect a pocket Geiger counter, nice reading skills though.
-- Thatonecommentguy, 2018-09-26

### *---- "Pointless"
It does nothing but give error messages and does not explain how to resolve them. The app makes you think that you are to blame for the errors. It gave me a headache. I'm deleting it now.
-- birdcatcher9, 2018-09-24

### *---- "Does not work"
Garbage, needs to be taken off of available download’s list.
-- Douglas2008, 2018-09-15

### *---- "Does not work"
Don’t bother
-- hydeubb, 2018-06-07

### *---- "I wish I could give zero stars"
I’m running 11.1.1 and I keep getting errors. 
“No connection”
“DeviceErrorTitle”
“DeviceErrorMsg”
“DeviceErrorRet”

I installed it twice with the same results.
-- BleuMoose, 2017-11-14

### **--- "This app actually doesn't seem to work"
I haven't figured out yet what conditions have to be in place for this app to work, but so far I have been able to get it to start about one time in six.  Definitely not ready for prime time.
-- Audiosaurus, 2016-01-12

### *---- "Does not work"
Does not work
-- Candymantook, 2014-05-23

### *---- "iPhone 5S not supported"
I bought the device, I bought this app and the pro app and only then it turns out that iPhone 5S is not supported and doesn’t get any meaningful readings from the device.
-- egorFiNE, 2013-11-08

### *---- "Still trying"
Unable to get past connection
-- Nixon1930, 2013-10-26

### *---- "Not cool to take away features on update"
First it was just the schematics for building your own detector that was part of the pro version. Now they took away features like adjusting threshold and time duration from the lite and moving it to pro only. Kickstarter funders should at least be given this functionality to adjust threshold and time duration. But still to take away features when it was originally included is not right.

Update for version 1.04:
Still didn't add back the features they took away from the previous version. The app used to look like the first screenshot posted but now you can only get that with the pro version. Rating still stands at 1 star unless they put back the features.
-- DSLKnight, 2011-09-15

### ***-- "Help!"
I need help with this app. I have a DRSB-88 geiger counter and some old tableware and on wikipedia it says that the old tableware is around 400 cpm. On this app it says its thousands of cpm. I dont know if im using it wrong or not. Help!
