What app does Ned Leeds create in Spider-Man: Brand New Day?

Ned Leeds creates an app called Spidey Tracker in Spider-Man: Brand New Day.

Ned builds the app because he wants to identify Spider-Man and thank him for saving Ned and his classmates during their high-school years. He does not remember that Spider-Man was actually his former best friend, Peter Parker.

The app shows how the memory spell changed Ned’s relationship with Peter. Ned and MJ have continued their lives at MIT, but both feel that something is missing. Their search for Spider-Man creates a path for Peter to reconnect with them without immediately revealing his identity.

The Spidey Tracker also appears after the credits, where it detects a Spider-Man sighting away from Earth. That detail links the film’s personal story to the larger MCU.
