Recently my coworker asked me if I could recommend any physical alarm clocks. He said that phone alarm causes him to pick up the phone the first thing in the morning and he wants to break away from this habit. I guess at some point the society as a whole will start fighting back.
I use a Garmin watch for alarms. Frequent conversation: "oh you have a smartwatch" "no it's dumb in all the right ways, which is the point" Notably I have notifications but can't act on them, which prevents me from picking up the phone just to check notifications and then be drawn into doing actions. YMMV.
I've tried that, but found them to be too easy to sleep through unless my watch wrist is very close to my head (without a pillow between it and my ear). The sound isn't particularly loud and the vibration is similarly shallow. Useful for reminder alarms when I'm awake though.
My current success is using the Amazon branded wiretap for alarms. Interacting with the dumb cloth-eared irritation sometimes annoys me into being awake rather than hitting the virtual snooze yet again, and it doesn't have the doom-scroll potential of my phone.
