Description
Do you know how much battery your iPhone has right now — without picking it up?
Battery Monitor Sync gives you a live view of every device's battery level across your iPhone, iPad, Mac, and Apple Watch. All in one place, all in real time.
Apple's own battery widgets show accessories like mice, keyboards, and AirPods — but not your iPhone, iPad, or Apple Watch. Battery Monitor Sync fills exactly that gap.
