FAQ

We strongly recommend joining the “deco-users” Google group to be informed of future releases and participate in discussions of DECO and its data. You can join the group here. Below, you can find a few of the most frequent questions.
 

Does DECO work on all Android OS?

DECO will work on most phones with Android 3.0 or later releases.
 

What do I do if Android blocks the DECO apps as unknown source?

You need to enable app sideloading. To do that, look in the “settings” menu and find the “security” option. Click on “Unknown sources”, which will will allow the installation of apps from other sources than the Google Play Store.
 

Is there a DECO app for iOS?

Not yet. We are working on its development and hope to release it in the coming months.
 

The DECO app seems to be running, but I cannot see any data. Is something wrong?

You can check a few things to make sure the app is working. Check the status, which should be scanning. Also, the number of samples should be increasing by a few per minute. To look at your data, please visit the deco data page. This website is updated once per day.
 

Is there a way to look at cosmic-ray events only?

So far, you need to look at all detected events and classify them. Cosmic-ray events will usually show as a track, i.e. a straight line in your image. We are currently working on algorithms that will allow automatic classification.
