Nissan Leaf owners, take note. The Leaf companion app is now available in both Android and BlackBerry flavors. These smartphone apps follow the steps of the iOS version that launched alongside the Leaf earlier this year. All the key features are here: battery level meter, charging schedule, estimated range, and climate control functions. The apps themselves are free to download, owning a Leaf is not required. But they understandably need a Leaf to properly function. Still, perspective buyers or curious onlookers can download and explore the apps for free.
