CityMapper does use OSM data, for walking and cycling in particular. (Cycling directions come via the OSM-based CycleStreets, I believe.) This really validates OSM's approach. Every single time there's a thread about OSM on HN or Reddit or whatever, someone pops up and says "Google rocks, OSM sucks, because your maps are dog-ugly and there's no routing/clickable Starbucks/whatever". Explaining to them that "no, OSM is just a dataset, osm.org is merely a minimal browser for map contributors" is hard. But having apps like CityMapper, which are actually _better_ than Google, really makes the point. Personally I'd choose a certain other OSM-based router over CityMapper/Cyclestreets for bike routing, but I may, ahem, be biased.
