Is it feasible to launch the app when the iPhone boots up?

No, an iOS app cannot begin running as soon as the device starts up. iOS places strict restrictions on background processes in order to preserve the stability and security of the operating system. Only programs that carry out specific tasks, such as playing music, tracking location, or providing Voice over IP (VoIP) services, are allowed to run in the background.
