About

PowrSync

Read full description

PowrSync keeps you on top of the battery life of every device that matters to you. Pair a phone or tablet in seconds by scanning a QR code, then see its exact battery level and charging status right from your own device โ€” no cables, no guesswork, no more "my phone died" surprises. Once paired, readings stay current on their own. When a paired device's battery changes, or it's plugged in or unplugged, your device is updated right away. Need an instant check? Request a fresh reading on demand and get the latest charge level within seconds. Stay informed without lifting a finger. Turn on smart alerts to be notified the moment a paired device runs low, finishes charging, or goes quiet โ€” PowrSync flags any device that hasn't reported in over 24 hours so you're never left wondering. And the built-in 24-hour history graph shows how each device's battery has trended through the day, so a quick look tells you the whole story. PowrSync is built to be private and lightweight. There are no third-party analytics and no ad trackers โ€” only the minimum needed to run the service (your email and a device identifier). You can delete your account and all associated data at any time, directly from Settings. Key features: - Pair devices instantly with a secure, single-use QR code - Real-time battery level and charging status for every paired device - On-demand refresh โ€” pull the latest reading whenever you want - Smart alerts for low battery, full charge, and offline devices - 24-hour battery history graph for every paired device - Clean, dark interface designed for a quick glance - Privacy-first: no ad trackers, no third-party analytics - Full in-app account and data deletion Great for keeping an eye on a child's iPad, a family member's phone, a spare device, or your own second phone.
