For any interested gamers out there using Nvidea Shield. As you might be aware amazon luna the cloud gaming service is not availiable on android boxes…well at least not easy to pull off. The service requires a firestick or tablet and select tv’s.
I was testing out the service but thought it would be so much better on the big screen but thats where my shield lives 
…so what to do? There are a few browser tricks one being the open web browser and I tried it but just not for me…too much fumbling through settings and wasting time… and I found this un-official app that works great and I thought I would pass it along…
