Proficiency in underwater communication is not only a vital part of scuba diving training, it also makes diving a much more enjoyable and safer experience. Scuba Diving Hand Signals intends to support beginning recreational scuba divers in learning underwater communication via hand signals. More than 240 commonly used gestures are illustrated and grouped into eight categories:

▻ Common signals
▻ Problem and emergency signals
▻ Training signals
▻ Number signals
▻ Air pressure signals
▻ Underwater wildlife signals
▻ Emotion and miscellaneous signals

Underwater wildlife signals are supplemented with images of each indicated animal and useful information about its features, distribution, and human interactions.

Last but not least, the app includes a quiz and tracks your learning progress which can be posted on Twitter or Facebook.

Perfect idea

This app is incredibly useful, I would gave 5 star ***** if you updated it.
This app doesn’t supported “Back Gesture” and you have to touch back bottom up there wich is not pleasant at all.

Developer Response ,

Thanks for the feedback. If enough users find this app useful, I'll certainly invest further work in it. Better iPhone X support, improved illustrations, some missing hand signals, and GUI improvements are already on the agenda.
