London Transport Alarm — Free on iOS
Sleeping, distracted, or lost in music — SNOZZ wakes you up before your stop. Every time.
Snozz was born on a late night tube home. After a long shift, exhausted and half asleep, I missed my stop. Again. Whether you're sleeping, distracted, or deep in music with headphones on — the problem is the same. So I built Snozz.
It was late. The kind of late that sits heavy on your shoulders after a long shift, when your eyes are already half-closed before you've even found a seat.
The tube rocked gently. London blurred past the windows. And somewhere on the way home, I fell asleep. I woke up at the end of the line. Again.
I searched the App Store. Surely someone had solved this.
So I built one. For everyone. I had never written a single line of code in my life.
The problems came one after another. Some small, some that consumed entire evenings — all of them solvable if I was willing to sit with the confusion long enough. Late nights. One laptop. No team. No funding. Just the belief that if this problem was real for me, it was real for millions of other people sitting in warm carriages across this city, drifting without meaning to.
Every obstacle had a solution. The solutions just required patience. So I kept going.
"The app does one thing. It does it well. It wakes you up when you're close to your stop — whether you're sleeping, lost in music, or just heads down. Screen locked. Phone in your pocket. Every time."
Snozz was built by someone who had every reason not to build it. And did it anyway.
