Pet battle smartphone app

What if there was an app that allowed you to do your pet battle dailies of tamers you have already beaten through your smartphone without having to fly all over Azeroth. Think it's a good or a bad idea?

Personally I am loving the legion companion app and the armory app and I think such a change would be a major quality of life improvement. I would also definitely pay up to 10$ just so I don't have to fly all over the place all the time. There are quite a few moments that I have free time with my cellphone but no computer nearby.
