Vortex Razor Phone Scope

Hi everyone, recently bought a Vortex Razor 13-39x56 spotting scope and wondering if anyone with this spotter has got some sort of a good phone scope setup. So far magview seams to be the best option but think it will be too big, can easily tape it or something to snug it up but would prefer not to. I'm wanting to stay away from switching phone cases and I don't want a massive bulky attachment to my current phone case either. If anyone with the same spotter has found a good solution I'd love to hear about/see it. Cheers
