It was first seen in Chore Wars, when Chase uses his Magnetism App to get his briefcase from Bree. The second appearance of the app was in Sink or Swim. In this episode, Chase uses it to escape the titanium rings that Douglas held him, Adam and Bree in. He used the Magnetism App along with his Molecularkinesis at the same time (also known as Two Simultaneous Abilities).
In Bionic Action Hero, Chase uses it on Troy West, by using reverse polarity. He uses the app again in the episode, The Curse of the Screaming Skull, when he was infected by the virus. He uses the Magnetism App to control the knives in the Mentor Quarters.
