About London Underground Alerter

This project started out as something I built for myself. Like most Londoners, I’ve had more than a few mornings derailed by unexpected Tube delays. I found myself constantly checking the Transport for London site or refreshing apps, just to figure out if I could get to work on time. It was a bit of a faff. Feel free to contact me if you have any suggestions on ways to improve the tool.
