Read full descriptionHide 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 ā 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 ā 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 ā 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 ā 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.

Every battery in your home and workshop, handled. Know what each device takes, keep spares in the drawer, and get a reminder before anything dies. For power tools, see which packs are charged and ready for the job. FOR YOUR HOME ⢠Add the TV remote, smoke alarm, AirTag, car key, scale or thermostat in a tap. 36 common devices come with the right battery already filled in. ⢠See exactly what each one takes: CR2032, CR2016, AA, AAA, 9V, LR44, hearing aid sizes and more. ⢠Battery finder: search 357 and get LR44, search DL2032 and get CR2032. Or point your camera at the code on a coin cell. ⢠Group devices by room: hallway, kitchen, garage. REMINDERS THAT MAKE SENSE ⢠Smoke and CO alarms get a monthly test reminder and a clear change date. ⢠Devices that fail quietly, like sensors and car keys, get a gentle "worth a check" with simple how-to-check steps. ⢠Things that tell you themselves, like AirTags, don't nag you. ⢠Log a change in one tap. The app learns how long batteries really last in each device. SPARES & SHOPPING LIST ⢠A drawer for your spare batteries: swipe a card to add one or use one. ⢠Set a minimum for each size. The shopping list fills itself in as devices come due, ready to share.
