Murmur AI conversation app joins three free Android and iOS tools for Portuguese users

A selection of four free mobile applications for Android and iOS has been highlighted. The Murmur app, created by Vadim Drobinin, uses artificial intelligence to simulate real phone conversations, offering users immediate feedback and tips for handling difficult calls. An open‑source keyboard provides a privacy‑focused alternative to mainstream options such as Gboard and SwiftKey. A navigation tool designed for motorcyclists helps plan routes and map trips. Finally, an unconventional game features an unlikely hero wielding a talking sword.

All four apps are available at no cost and target users seeking productivity, privacy, travel planning, or casual entertainment on their smartphones.
