The crowd-sourced traffic and navigation app Waze is getting a bit of a makeunder on iOS.

Waze Version 4.0, released Monday for iOS and expected to arrive on Android soon, brings a simplified interface with less clutter, a new feature that will help you leave on time for Calendar events, and battery life improvements.

"After installing Waze, you'll immediately notice a newer, cleaner design that makes for easier navigation, reporting, and sharing — you might call it a brand new Waze experience," the Google-owned company wrote in a blog post. "Now, it takes [fewer] taps to access many of Waze's key features."

Just tap the button in the lower left corner of the app to pull up the navigation menu, including all your frequent and favorite destinations. The button on the lower right lets you access your contacts as well as send other people directions, your location, and ETA.

The center button, where your ETA is displayed, lets you view alternate routes, add a stop, or let someone know you're on the way. The big orange button on the map will bring up a redesigned reporting menu, where you can report accidents, traffic, gas prices, road hazards, issues with the map, and more. You can also now tap and hold down this button to more quickly report something.

Besides the interface changes, Version 4.0 includes a new feature that will send you reminders about when to leave for calendar events, based on traffic. Just sync your calendar with the app and make sure to add a street address to your event locations and Waze will watch out for traffic and tell you when to hit the road.

Finally, Waze said that this version "significantly reduces battery consumption" so you'll have more juice when you get to your destination.
