What API to use to create IOS/Android app with navigation?

Question

Mobile development

It is necessary to add turn-by-turn navigation to the application, I looked in the direction of Google maps, google directives - it seems like terms of use cannot be created such an application. There is another option Scrobbler.com. But still I would like to hear from those who had experience using something similar to choose the best service for navigation.

Everything depends on the requirements. GraphHopper has a good API out of the box. You can see embedded solutions like brouter. OSRM again.
