In france, and in particular in Paris, https://www.geovelo.fr/ is very very good. It knows about various Parisian specialties (going the wrong way on residential street is allowed, temporary bike paths, mixed pedestrian/bike paths, etc) that other apps don't really understand. It also gives multiple paths depending on various criterion.

OsmAnd is also decent. Google map is terribly bad.

Geovelo is indeed very practical in Paris! Well made and provides choice between "secure" and "fast" journeys, it also show how many % of the proposed paths are protected bike lanes and has shared information on hazards on the road!
