Click. 

Click. Click. Clickclickclickclick. Click — do you hear that? That's the sound of folks everywhere broadcasting their support for Republican presidential nominee Donald Trump. It's the sound of the Click Together app — aimed at bringing together Trump supporters nationwide — that topped the iTunes paid-app chart Tuesday.

It is a very simple app, created by a 77-year-old army veteran Jon Ross. The app is based on a tool employed by World War II paratroopers called the cricket, which made a clicking noise to communicate in the darkness and while under enemy fire. The app, which costs $0.99, simply recreates that noise. You tap your screen, it makes a noise. That's all it does. The app has no menu to navigate options, only an information page explaining the history of the cricket device. The sole reference to Trump is the prominent displaying of the GOP nominee's slogan, "Make America Great Again."

Ross appeared on Fox and Friends Tuesday to discuss his app and get the word out to Trump supporters. His motivation for creating it, he said, was to unite the country, or, it seems, at least roughly 40 percent of it. 

"Well, we've got to do something for this country, we've got get it to get together, because it's very fragmented," Ross said. "I said, 'Where did have we had a problem with security or, you know, a tipping point in our times?'"

Ross then seemingly compared Trump's candidacy against Democratic nominee Hillary Clinton to George Washington crossing the Delaware River during the Revolutionary War and the invasion of Normandy during WWII. 

"At Normandy, when they dropped in, had Hitler released those two armored divisions, we might be speaking German," Ross said.

After a back and forth about crickets, host Ainsley Earhardt seemed a bit confused about what the app actually did, asking Ross, "So on your phone if you walk into a party and there are Trump supporters, you'll get a notification that other people are on your app? "

"No, I don't have that, but if you go in there and click and somebody else has got one, then they'll click too," Ross said. 

Much like Earhardt, your intrepid International Business Times correspondent was initially a bit perplexed about what the top-selling app did. The correspondent, in turn, spent nearly an entire dollar on the app and it really is that straightforward. However, it might not only be for Trump supporters, because even if you're #WithHer or undecided, it can also serve as a nifty tool for annoying co-workers who just want to get some work done in a little peace and quiet.
