Was just wondering if anyone uses the ZELLO app to communicate during storm chases. When I had watched Barry Gray in some of his videos, I noticed that he was communicating to other chasers with his phone, but I didn't know what app he was using. I found out it is ZELLO. Does anyone have any positives/negatives about this program. @Warren Faidley we might want to download this app if it's pretty decent to use.
