Jala Talk app for iPhone and iPad

Jala Talk is a private and personalized messaging platform for mobile equipment. Its focus is on allowing organizations to create their own means of communication, having control over their data, their security, and the communication costs. The drop in costs is due to six times less data consumption than using other messaging applications.
Jala Talk encrypts all data in the private communication flow, storing data only on the device itself. Only the sender and addressee can see these data.
Besides text messages, the application allows sending photographs, audio, and high-quality video using lower-capacity communication channels.
