To my mind, this is the greatest application for storing XMR. It is reliable enough because of too many different security features. They start with PIN and 2FA, continuing with e-mail confirmations, biometrics, and so on. I also consider this wallet from Freewallet as a promising one, because it works much faster and takes lower fees, then any other wallet I know or have tried in my life. Would like to recommend this Monero application. Thanks. See full review
