Some Easy Poketch Apps.
Go to Sunyshore City. Go to the place where the Munchlax Rock is located, then use Rock Climb to get to the house beside it. Talk to the man inside the house. He will ask you for a specific pokemon nature. Your pokemon's summary should tell you which nature they have. (Go to pokemon on menu. Pick a pokemon and pick sumary.) Do this, and you will get Poketch Apps. He will ask for three different natures one at a time. You only get THREE types of Poketch Apps. I hope this helps! :)
