Mapview offers route optimization for routes with more than three flexible meeting tasks. You can optimize routes that have a combination of set appointments and flexible meeting tasks. Mapview's optimizer will work to fill in the gaps around set appointment times making you more productive while on the road.
To optimize, simply tap the Optimize button at the bottom of the 'Trips' window and choose between the three different optimization options: ‘Time’, ‘Distance’ and ‘Balanced’. Time favors the fastest route, distance favors the shortest distance and balanced combines the two.
