Monitor another device's battery from your own phone
PowrSync is an iOS app that lets you watch the battery level and charging status of a family member's iPhone or a kid's iPad, live, from your own phone. iPhone and iPad, iOS 16+.
Battery monitoring built for the people you care about
Keep a kid's iPad, an elderly parent's phone, or a spare device from running flat, without ever picking it up.
Share your charge, live
Open any device to see its current charge, whether it is plugged in, and a 24-hour battery history graph that updates the moment the level or charging state changes.
Loved ones, in the loop
On the monitored device, scan a QR code once to pair. From then on it quietly reports its battery to everyone watching over it, and shows you exactly who that is.

What does PowrSync do?
PowrSync lets you monitor the battery level and charging status of another device, such as a family member's iPhone or a child's iPad, live from your own iPhone or iPad.
How do I pair two devices?
One device acts as the Master (the one watching) and the other as the Slave (the one being watched). On the Slave, open Show QR Code. On the Master, tap Add Device and scan that code. Once paired, the Master sees the Slave's battery level and charging status.
Which devices are supported?
PowrSync runs on iPhone and iPad with iOS 16 or later.
Does PowrSync work in the background?
Yes. PowrSync refreshes battery readings in the background so the watching device stays up to date even when the app is closed, as long as Background App Refresh is enabled.
Is my data private?
Yes. PowrSync collects only what it needs to run the service and uses no third-party analytics or advertising trackers. You can delete your account and all stored battery history at any time from Settings.
How much does PowrSync cost?
PowrSync is free to download and start using, with an optional Premium subscription that increases how many devices you can monitor.
