Walkity stands out due to it's unique features. The prime feature is the SLAM (Simultaneous Localization and Mapping) integration. It enables the "Return Home" functionality to work without an active connection with the mobile device. In other words, Walkity temporarily lays breadcrumbs along the route and follows them back to home without needing the help of a smartphone.

Walkity is also equipped with a strong communication channel. It uses cryptographic standards like RSA to lock messages to enforce a defense mechanism against malicious attacks. Apart from the software side, Walkity encloses a ultra-thin and  bendable Li-ion cell to provide an extended battery life of two weeks.
