how do I stop a timer when the app gets into the background or user exits the app

how would I go about to stop a timer when the user exits out of the app, clicks the power button, or gets sent to the background, I realize we can listen to Darwin calls but I do not know how to go about with that.

here's an example from the log out put:

at update 2 I shut the phone off, then at update 6 I turn it on and open the app
