Telegram is a messaging application for iOS, Android, and desktop. The app focuses on security for cloud-based mobile, and aims to withhold user privacy. An SDK is available to create messaging applications in iOS devices. With an app built using Telegram SDK, developers can connect from remote locations, coordinate groups of up to 200 members, synchronize chats in all devices, destruct messages with a timer, encrypt personal and business secrets, and build tools with the API.
