Although Apple has started to delete the applications of those who shamelessly copy popular applications from the App Store, the applications made by developers just with the idea of "pulling a punch" on users remain without problems in the store of the Cupertino company. Today I have for you an application called RoomThermometer that promises to tell you the temperature of the room using only sound waves and all in just 20 seconds without using an internet connection.
The RoomThermometer app allows you to know the temperature of your room in 20 seconds. Since it only uses a sound wave that reflects off a wall, no connection to a Wi-Fi or 3G network is required.
Of course, the application is just a trick because it has no way of telling you the temperature inside a room in this way. If you are tempted to buy it, I recommend that you give up the idea.
