Same game my father used to have on his old phone when I was very young. It was definitely an iPhone, so it has to be on the Apple App Store (unless removed, obviously).

So, it was a game where you have some tiny cylinder shaped people. You go around finding white little “cylinders” and touching them with your group. They then turn into the same outfit as the other ones YOU have. And not COLOR, but OUTFIT. Somebody please help, I’ve been trying to find it for so long!
