Yeah there’s something about phone speakers that just never does the job for me. I dunno, the alarm sounds just lack…presence. I use a bell-based alarm clock to wake me up and when that thing goes off, you’re getting the fuck up no matter how deep a sleep you’re in. Phone alarms? I’ve slept through too many to count.

Obviously your use case is different, I’m just thinking if it can snap out a deep sleeper like me, it might help break your hyperfocus too.
