I'm sure you've already heard about Freewallet. They have a pretty decent XMR app for Android that I'm using. They also have a web app if you like to use PC. Another good thing they have a built-in exchange that I'm frequently using because I'm scared of the real exchanges.
https://app.freewallet.orgThis is really a very bad cryptocurrency wallet because still lot of people complaining about using funds while depositing are sending the cryptocurrencies so never suggest anyone about freewallet.
