monerujo app
Monerujo is an Android wallet for Monero, an open-source cryptocurrency created in April 2014 that focuses on privacy, decentralisation and scalability. Details on the app can be found in its FAQ, as well as some screenshots (behind the links in there).
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!
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. (getmonero.org)
Note: Some scanners on VirusTotal throw false alerts here, detecting some kind of "Bitcoin-Miner". Well, this is a crypto-wallet, so it deals with crypto currencies. And this is an Android app, not MacOS as those reports claim.
