About
You didn't mean to fall asleep.
But the seats are warm, the carriage rocks, and London blurs past the window. One moment you're on your phone; the next, you've missed your stop.
It happens to everyone. The exhausted commuter after a double shift. The tourist who doesn't know the route. The elderly passenger on an unfamiliar line. The student is heading home at midnight.
Snozz was born on a late-night tube home.
After a long shift, exhausted and half asleep, I missed my stop. Again. I looked for an app that would wake me up at my station — nothing good existed. So I built one.
Snozz is the alarm that travels with you.
Set your stop. Close your eyes. We'll wake you up when it matters.
