What's the best iOS app for controlling my dance game when the kids lose the game controller... again?

Look, I'm running a business here, I don't have time to chase down controllers. My kids love their dance games, but those little remotes? They disappear faster than profits in a bad quarter. This Just Dance Controller app? It's a lifesaver. Turns the iPhone into the controller. Setup is straightforward, even my kids can manage it. The motion tracking is decent enough for a casual game night. I'm not expecting pinpoint accuracy, but it's good enough to keep the game going. Plus, it's one less thing I have to buy when the original goes missing. Honestly, for a free app that keeps the peace and saves me from buying another overpriced controller, it's worth every penny. It's not perfect, but the ROI is solid for family fun.
