Back in college, I used to doze on the bus during my 90-minute commute to an 8 A.M. history class. Most of the time, those extra Z’s were fitful, constantly interrupted over the fear that I’d missed my stop. is hoping to put an end to those fears for current students other commuters.

A new feature recently popped up in Now on Android that lets you set an alarm on your phone to go off when you arrive at your destination via public transit. The new feature relies on your saved home work locations to surface alerts when you need them, according to Android lice, which first reported on the new feature.

ether public transit alarms are available to you depends on where you live, since the feature likely ties in to Maps’ public transit directions, a feature first introduced in 2005.

supports public transit routes in numerous countries worldwide a vast number of locations across the U.S. To see if Maps has your transit system covered check out the Transit cities list.

Beyond Maps, there’s also the nebulous issue of whether the Now feature is rolled out in your area. Android lice nabbed screenshots from the Netherls, which suggests that public transit destination alarms via Now are either being tested in Europe or they’re already available in most countries worldwide.

To see if the new feature will work for you, make sure Now is set to give you public transit directions by default. Do that by opening Now, scrolling down to the bottom, tapping the magic w icon. Next, go to Everything else > How do you usually get around? select “blic transit.”

Beyond that, start using Maps’ transit directions when you need to know where you’re going, check Now while you’re riding the bus.

That doesn’t guarantee you’ll see the new feature, but at least ‘s magic algorithms can identify you as someone who would benefit from public transit destination alarms.
