On Time reads your calendar, uses live traffic to work out the exact moment you have to leave, and locks the apps that make you late until it's time to go. The whole app comes down to one number — how long until you leave.
It syncs your calendar and checks live traffic to each event with a location, then counts down to the exact minute you need to head out the door.
When it's time to go, the apps that swallow your time lock automatically. Start moving and the lock clears on its own once you're on your way.
Try to open a locked app and a full-screen takeover makes you stop and think — and, if you choose, lets you text the person you're meeting that you're behind.
There's no account and no server of ours — On Time neither collects nor shares any of your data. Travel times are estimated with Apple's Maps service; everything else stays on your iPhone.
