Presumably inspired by socially distanced birthday parties, Blower is a $2 iPhone app that can blow out a candle by holding the speaker up to the candle. What a time to be alive and celebrating another trip around the sun! The app works by generating pressure waves from the phone’s speaker using a particular tone around 240Hz. The app also has a function that connects to your phone’s mic so it turns on when it hears the sound of blowing, so you can blow out your birthday candles without spitting all over the cake. Neato. Of course this would never work with my phone because the speaker holes are so jammed full of lint that I can barely hear my girlfriend on the phone when she’s yelling at me, which is nine times out of eight.
