Blower on the iPhone’s App Store enables the iPhone to extinguish a candle. The free app on the App Store is 1.99 Dollar and is still one of the eight most popular apps on the App Store.
The developer says that the app takes advantage of some secret features in the iPhone’s electric circuit and enables its speakers to blow air in a blown manner.
In addition to the iPhone, it is also available for the iPad and iPod. However, it only supports iOS / iPad OS 11.0 or later.
