No this is not like the iPhone shaver, Blower by Qneo is an actual app and it actually does make your iPhone blow air, kinda.
The app doesn't require any external device, it uses the built-in speaker and by simply playing a certain sound at a certain volume, it creates enough vibrations to make your iPhone blow air.
The developer actually thought this through and affirms you can use it to:
blow out candles, herbs, and refresh your skin during hot summer nights
I wouldn't personally be playing with my iPhone around candles too much and who knows if this doesn't damage the speaker, but yeah, might be fun. Check out the video demonstration:
