Blower is a great and fun app to blow out the candles. As well it's nice speaker cleaner, load noise and high frequency waves remove water, dust etc from the phone. Fix your speakers and make them sound clear tone. Make your birthday special, surprise your friends with an unusual way to blow out candles. For maximum blowing power use a phone with a strong/working speaker, remove the protective cover. Using the app is absolutely safe, but do not forget about safety measures when working with fire.
