## What is おでかけ逆算?

“What time should I leave?” Get the answer from your getting-ready time, travel time, and buffer.

Leave on Time works both ways: plan backward from an arrival to see when to get ready and leave, or start from a departure to see when you will arrive. Change a duration and the three key times update together on one screen.

Use it for meetings, reservations, commutes, school runs, or a day out. Stop recalculating times in your head and see the next time you need to act. Maps is optional—you can enter preparation, travel, and buffer time manually.

Features
• Calculate from either a departure or an arrival
• Adjust preparation, travel, and buffer time
• Search origin and destination with Apple Maps and estimate walking, driving, transit, or cycling time
• Work fully manually without Maps or location
• Local reminders for getting ready and leaving
• Preparation presets, recent-plan history, and a short note

One purchase includes every feature. No account, ads, in-app purchases, subscriptions, analytics, or tracking. Plans, presets, and history stay on your device.

Apple Maps travel times are estimates and can change with traffic, service conditions, and route availability. Adjust your buffer and check current guidance before you go.
