How do I achieve turn by turn navigation on AI2?

Actually, this is not true. I specifically implemented the ResponseContent property that returns the GeoJSON response of the service as a JSON dictionary. ORS returns information about list of steps and each step structure contains the text of the step and the indices of the waypoints that indicate the segment associated with that step. For each step, you could extract the end waypoint index and use that to look up the lat/long in the points list, e.g.: { "type":"FeatureCollection", "featu…

Note that the waypoint numbers are 0-indexed whereas lists in App Inventor are 1-based, so you will need to add 1 to each waypoint index of interest to get the corresponding point in the coordinates array
