AquaApp is an instant messaging application Only available for Android smartphones. But it has a unique feature: works under waterIt is an element known to weakly emit radio waves from our smartphones (their range is limited to a few centimeters at best). App designers have managed to overcome these limitations by using our devices’ microphone and speakers to send and receive messages. In fact, sound travels very well in water.
As the academics noted when presenting their software, underwater digital acoustic communication devices existed long before AquaApp. However, the technologies used reserved their use for professionals and scientists. Here, no need for additional hardware or accessories to communicate underwater.
General public can access underwater mobile messaging with AquaApp
Providing a reliable messaging application that can be used in a variety of underwater environments is a challenge. Scientists say they tested AquaApp in six different underwater environments, at depths ranging from 2 to 15 meters, in the presence of boats, ships and people fishing or canoeing. Communication systems adapt in real time to the different frequency responses of all types of mobile devices, as well as to various audio environments. According to them, AquaApp can be used under certain conditions Range up to 30 meters (100 m in ideal conditions).
At first glance, AquaApp will attract the attention of scuba diving enthusiasts. The programmers integrated 240 vignettes representing signs used by underwater enthusiasts. If you want to test the AquaApp while scuba diving or in the pool, remember to place your device in a waterproof protective case. The application is free. Additionally, AquaApp is open source and its code is available on Github. The app works on all new versions including Android 12 and Android 13.
