Use Your Poketch
Brilliant Diamond & Shining Pearl Tips & Tricks
The Poketch is rife with a lot of silly apps, like a Calculator that it’s easy to just write it off as being useless. However, intermixed with the silly apps are ones that are actually useful and that you should keep an eye on from time to time.
The first one is the friendship checker. This app tells you how much your Pokemon loves you. If a Pokemon has two large hearts above them that means that the friendship is maxed out and, if they evolve via max friendship, they will evolve the next chance they have.
The Dowsing Machine is a big one as that’s what lets you find hidden items, which can include useful things like evolution stones or even Rare Candies. There’s also the Berry Searcher which tells you when there are Berries ready to be harvested on the map.
Definitely play around with your Poketch as you get new apps and try them out.
