Clicker dog trainer app for iPhone and iPad

It is a clicker that is a very effective means of training dogs. I guess cookers are handled in most pet shops. The price is about 1000 yen, but this software is free. Even if you forget the clicker for a walk, you will not forget the smartphone so you can use the clicker anywhere.
In addition, since we prepared a lot of training, we can train and train pet dogs easily from beginners.
I made it for my domestic dog training. Moreover, since this software is making it as a hobby after retirement from retirement, please understand that point and use it.
