About London Underground Alerter

London Underground Alerter exists because disruption is unavoidable, but useful updates are oddly hard to get at the right time. Most services either bombard you all day or make you wade through another app.

Here, you choose your lines, set the exact time windows you care about (like commute hours), and get quick, plain-English updates by email. No downloads, no notifications to manage, no extra faff.

If you would like to learn more, see the About Us page.
