Monerujo is the first app for managing and using Monero wallets on Android. It is a lightwallet: it uses remote nodes for synchronizing to the Monero blockchain while keeping all your private data on your device. You can run your own node at home or connect to nodes provided by the Monero community - it's up to you!

What is MONERO? It is Private Digital Currency.
Monero is a secure, private, and untraceable cryptocurrency. It is open-source and accessible to all. With Monero, you are your own bank. Only you control and are responsible for your funds. Your accounts and transactions are kept private from prying eyes.
