Maps and travel time
Estimate with Apple Maps
Search for a destination and origin, then choose walking, driving, transit, or cycling to request an arrival-based travel estimate.
Current location is optional
The app asks for location permission only when you choose your current location as the origin. You can search for an origin or enter travel time manually instead.
If no route is available
A route may be unavailable because of connectivity, region, or travel mode. Enter the travel time manually to keep planning.
Reminders, presets, and history
Local reminders
When you set reminders, the app schedules on-device notifications for future preparation and departure times. iOS retains the trigger dates until delivery, cancellation, or an update caused by editing the plan.
Preparation presets
Name and save preparation times you use often, then reuse them in a new plan.
Recent plans
Restore time settings from history. You can remove history and presets inside the app.
Frequently asked questions
I did not receive a reminder
Open iPhone Settings, select this app under Notifications, and confirm that notifications are allowed. A reminder cannot be scheduled for a time that has already passed.
Do I have to allow location access?
No. Search for an origin and destination, or enter travel time manually, to calculate without current-location access.
How do I remove saved information?
Delete history and presets inside the app. Removing the app from your iPhone also removes information stored in its app container.
