Breeze Thermometer

What would happen if an app that emits a gentle breeze from a speaker and a thermometer app were combined?
This app is the realisation of such a dream combination(?).
This app produces a gentle breeze from the speaker using special sound waves that can generate a breeze from the speaker, and because it has a thermometer attached, you can see the dew point temperature(outside) and the outside temperature.
The dew point temperature is the temperature at which a cold object (e.g. well-chilled soda) starts to sweat, a phenomenon also known as 'condensation'. If you know the dew point temperature, you can help prevent condensation, which is a contributing factor to iPhone malfunctions.
PS: The function to produce a weak breeze from the speaker is of no practical use, so we strongly suggest that you use it for joke purposes. On your birthday, use this function to extinguish the candles on your birthday cake (LOL).
