Monerujo allows users to easily manage and store their XMR coins, as well as make transactions on the go. It is an open-source software, which means that its code is publicly available for anyone to review and contribute to. The wallet features a simple and intuitive interface that makes it easy for users to navigate and perform various functions such as sending and receiving payments, checking transaction history, and managing account settings. Monerujo also provides advanced features such as offline transaction signing and built-in coin mixer for added privacy. Additionally, Monerujo uses MyMonero service as its backend, which means that the user's private view key is never stored on the device and is not sent over the internet.
