I don't have a mobile recommendation but here's what I do:
My normally sweet, docile cat turns into a violent murderer when I trim his nails. Plus he's large so the damage he could do is a bit more intense.
On the first of every month he gets his nails trimmed and I time it right before a meal. I have had great luck by putting on this cone which I already had for my dog and then using a fleece blanket to wrap his body up like a burrito with one leg at a time showing. (I've also seen these cones but not used them)
He hates the burrito just as much as the process and the cone but with more and more experiences we've gotten to the point of being able to usually do two paws, sometimes three, without needing to be burrito wrapped.
When we're done I take off the cone, I don't try to pet him but one at a time give him 3-5 high value treats. The first one I throw to him, the 2nd one I throw a little closer to me, etc. When we get to the one where he's close to me I start to give him a quick light head scratch. When I put them away he's rubbing against me for more and then I pick him up, give him his favorite chin scratch and apologize. When he's fully relaxed I take him to his tower to eat.
