Yes,Taiwan the only thing more inane than an actual fidget spinner is an app version of a fidget spinner.

Still, ridiculous as they are, the apps are -- inexplicably -- nearly as popular as the toys themselves. Seriously.

Of all the "fidget spinner" apps -- and there are hundreds -- the most popular by far is this app from Ketchapp simply called "Fidget Spinner." The app, which hit the Ap Store May 16, has already racked up more than 7 million downloadsacross Apple's App Store and Google Play, according to statistics from app analytics firm Sensor Tower.

That's right: more than 7 million downloads in just over two weeks. Now, that's no Pokémon Go,which hit 10 million downloads in a record-setting seven days. But it's remarkable for an app that's, in the words of Mashable'sesports reporter Kellen Beck, "is the worst resource-collecting game I've ever played on an iPhone."

Ketchapp, the game studio known for churning out chart-topping addictive games with intrusive app-install ads, is far from the only developer seeking to capitalize on the fidget spinner craze. There are about 300 fidget spinner apps across both Apple's App Store and Google Play, according to Sensor Tower's analysis.

Again, none of these are nearly as popular as Ketchapp's, which spent nine days as the number one free app on iOS, according to App Annie (it's currently sitting at number seven). But that's pretty incredible momentum (pardon the pun) for an app that does nothing besides let you spin a virtual fidget spinner while watching obnoxious -- and no doubt highly lucrative -- ads in between sessions.
