Found this on Reddit, was sceptical because the app was free.
Here is my review:
Turned out to be the best thing I've downloaded in years.
I only hold Bitcoin, Litecoin and Ripple (for testing) and the results are impressive.
Quick in realtime my 'Wallet Value' for my three coins per coin and in total.
I could even choose to have al values in other currencies than EUR.

My advise, download this while it is still free.

Below the text and link as found on Reddit.
