Citymapper is a public transit app and mapping service[4][5] which displays transport options, usually with live timing, between any two locations in a supported city.

[6][11][12] In December 2019 the app added a feature which allows users to choose between a "fast" route or "main roads" which avoid dimly-lit areas.

[14] In September 2017, Citymapper launched a night bus service in the East End of London.

[19][20] In February 2019, Citymapper launched Pass, a weekly subscription that gave users access to some forms of public transit in London, at lower cost than other weekly passes.

The company plans to use the funds to expand services into additional cities.
