I tried 9 ways to wake up on time. Only one actually worked.
A gentle buzz on the skin wakes people up in a different way than sound does, so it works even for ADHD brains that sleep through alarms.
Let me save you the mornings I wasted.
I set the loudest alarm my phone had. Then three alarms, five minutes apart. I put the phone across the room. I bought a sunrise lamp. An app that made me solve math problems to shut it off. A smartwatch. An old alarm clock. I went to bed earlier. And I asked my girlfriend to shake me.
None of it worked. Some mornings I slept straight through. Other mornings I turned it off and remembered none of it.

Your brain ignores sound. Not vibration.
Researchers have a name for this. Low registration.* An ADHD brain needs a stronger signal before it notices anything at all. So a louder alarm does not help. It is the same kind of signal, only turned up. A buzz on your skin is a different kind.
Made for brains that work differently.
*Systematic review and meta-analysis of 30 studies, 5,374 people. Low sensory registration was substantially higher in people with ADHD than in controls. Journal of the American Academy of Child and Adolescent Psychiatry, 2025.
I woke up on time. Without the panic.
"A buzz will never wake me up."
That was my first thought too. I sleep through a phone screaming next to my head. But this one does not buzz once and give up. It keeps growing, through three levels, until you are up.

Nine things. Two years of late mornings. Every one of them was another sound, and sound was never the problem.
