Example · 4 min walk · no extra time added
Add extra time if you need it.
If you need time to leave the building or wait for an elevator, set extra time in Settings, from 0 to 15 minutes. Stratus counts it with your walk.
Metra works
the same way.
Metra times show the same three results. Metra runs to a timetable, so each Metra row also shows the scheduled clock time. All 11 Metra lines are included.
