Hurricanes Harvey and Irma has led to the growth in popularity for walkie-talkie app Zello, which now tops Apple’s app store chart.
As Hurricane Irma tracks toward the United States, leaving at least 13 dead in the Caribbean, the walkie-talkie app has become a go-to tool for rescuers, according to the Washington Post.
Alexey Gavrilov, founder and chief technology officer for Zello wrote about the influx of downloads in a blog post on Wednesday.
“We have seen a large number of people signing up for Zello in preparation for Hurricane Irma. Over 1 million people have joined in the last day, with most coming from Puerto Rico and Florida,” Gavrilov wrote.
Zellow sent a series of tweets about the downloads on Tuesday, saying they’re experiencing an “unusually high rate of sign ups” which led to performance issues for some users.
Hurricane Irma remains a Category 5 storm as of the National Hurricane Center‘s 11 a.m. advisory and the storm continues to move on a west-northwest track.
A hurricane watch has been issued for parts of south Florida and the Florida Keys. Irma has maximum sustained winds of 175 mph.
