Applications for pets?

[ElGuapo96]

Are there any good applications for pets in general, and if possible specifically dogs? The function of the application doesn't matter. It could vary from training your dog to counting it's calories, all the way up to actually giving it commands. It would be awesome if there was an application that can actually help you or even teach you how to train your dog. I am struggling a bit with my Rotweiler, since he is so full of energy but cannot really control it
I feel like having a tool to help me would be amazing. Especially because it would always be with me and i can just pull it out and do whatever the app tells me to do.
