iGap is a free messaging application offering text communication, voice calls, and video calls over internet connections. The service operates across multiple network types, including 4G, 3G, 2G, EDGE, and Wi-Fi, accommodating various connectivity scenarios. All user communications are protected using a two-layer encryption system combining 256-bit AES encryption with 2048-bit RSA encryption.
Text messaging automatically synchronizes conversations across all devices linked to a user's account. Messages sent or received on one device appear immediately on all others, creating a seamless experience when users switch between devices. Messages are stored in cloud infrastructure rather than on individual devices, eliminating local storage concerns while preserving the complete conversation history indefinitely. Users can reference past conversations from weeks, months, or years earlier without messages being deleted due to device storage constraints.
Group conversations function identically to individual chats. Multiple users can participate in shared group discussions that synchronize across all participants' devices and persist indefinitely in cloud storage, allowing any member to reference past discussions and shared context at any time.
Voice and video calling are included without additional charges beyond the internet connection required to use the application. Both call types use peer-to-peer technology, routing connections directly between participants rather than through centralized servers. iGap's globally distributed network of data centers supports this approach by managing infrastructure, maintaining service availability, and facilitating peer-to-peer connections.
File sharing operates without restrictions on file type or size. Users can send any form of media or data through conversations—images, videos, documents, archives, or other formats. Like text messages, shared files are retained in cloud storage and remain accessible across all user devices indefinitely, ensuring no content is lost due to device changes or storage limitations.
All conversation data and files are stored on remote servers rather than on individual devices. This centralized approach provides practical benefits: users who lose a device, purchase a new one, or reinstall the application can access their complete conversation history and all shared files without data loss. Additionally, local storage burden is minimized since the application only caches currently active conversations rather than storing comprehensive local histories.
Device synchronization extends beyond message delivery to encompass all changes to conversations. Newly received messages, deleted messages, edited content, and received files reflect across all connected devices in real time, as do call history and communication records. This ensures users observe the same conversation state and communication history regardless of which device they use.
Encryption protecting messages employs a two-component system designed to balance security with performance. AES-256 encryption secures message content using symmetric cryptography, while 2048-bit RSA encryption manages key exchange for secure key distribution. This combination provides the efficiency of symmetric encryption alongside the key-distribution security of asymmetric cryptography.
