I would like to present you CryptoCoinsManager. This android application is a kind of crypto currency tracker. It allows you to watch in a dashboard all the currencies you own (among others XPM), their values in BTC and fiat currencies. You can do this by entering the amount manually or using you wallet public address (except XPM, I did not found any api to get address balance). It cannot send or receive payments by itself, it is completly safe, it is free (to be honest, there are ads).
It is still in beta but it works well. So give it a try, You will like it.
If you like it or want new features, do not hesitate to contact me.
