Is that kosher?

So last night, I went on a run. 2.15 miles and used the Nike app. No real preference. I think it came with my iPhone already installed? I'm not sure. 

My dilemma was to tag my new shoes or not. It is the Nike app. But I did not buy Nike shoes. Is that Kosher? It wouldn't automatically let me me choose other brands so I manually put it in? Has anyone else done this? Just curios. #firstworldproblems
