AirBattery Review

Open-source battery levels for every device

Visit AirBatteryΒ·Free & open source

A free, open-source tracker that puts every nearby device's battery on your Dock, menu bar and widgets.

AirBattery is a free, open-source Mac app (AGPL-3.0, distributed via GitHub and Homebrew) that reads battery levels from just about everything near your Mac: iPhone, iPad, Apple Watch, AirPods, Magic accessories, and even other Macs on your network through its Nearcast feature. It shows those levels on the Dock icon, in the menu bar, and in desktop widgets, and it can fire per-device low-battery notifications. Feature for feature it is the closest free cousin to Juicy's device tracking, but it stops at tracking: alerts arrive as standard macOS banners, and there is no battery health analytics, no charge limiting, and no Mac App Store version.

What AirBattery does well

  • Completely free and open source (AGPL-3.0)
  • Wide coverage: iPhone, iPad, Apple Watch, AirPods, Magic accessories, other Macs
  • Nearcast syncs battery levels across Macs on your network
  • Dock, menu bar and desktop widget display options

Where it falls short

  • Alerts are standard macOS banners, easy to miss when it matters
  • No battery health analytics: no cycle history, temperature or voltage
  • No charge limiting to protect the Mac battery long-term
  • iPhone, iPad and Watch need a USB trust pairing or shared WiFi to appear

4.9 on the Mac App Store

The battery alerts Apple should have made!

3 days in and Juicy has already saved me from my laptop dying while on a call. If that's not a win, I don't know what is!

Delightful app

Sometimes you should enjoy the little things in little... Like the beautiful notifications of this app!

This is why I like Mac OS

It can tell you that your battery is low as well as your battery health. This IS what I need for my Mac.

Purchased the app recently, GOOD STUFF to buy

The app has a very clean and well-thought-out design, and it works flawlessly. Compared to other Mac battery apps, it performs exceptionally well. I'm really impressed and looking forward to seeing even more functional and beautiful design updates in the future. I'm definitely sticking with it!

Beautiful app, really useful

I swaped my standard Mac battery icon immediately with Juicy's one after installing the app. Love the craft and usefulness of the app

Awesome MUST have

Being able to set a full screen alert at 2% and 1% charge left has saved me from suddenly getting kicked out of Zooms and other calls before it's too late.

Great product!

It's such a simple and cool product! Already saved me a couple of times from getting and empty laptop!

Frequently asked

Is Juicy an AirBattery alternative?
Yes. Juicy tracks the same devices (AirPods, iPhone, iPad, Apple Watch, Magic Mouse, Keyboard and Trackpad) and adds glowing notch alerts, live battery health analytics and charge limiting, which AirBattery doesn't do.
AirBattery is free though. Why pay for Juicy?
If device battery levels are all you need, AirBattery is a great free choice and we'd happily recommend it. Juicy is for people who also want alerts that are impossible to miss, health and cycle tracking for the Mac itself, and a charge limit, all in one native app that's developed full-time.
Can I run AirBattery and Juicy at the same time?
Yes, they don't conflict. Most people find Juicy covers everything they used AirBattery for and quit it after the trial. One honest exception: if you rely on AirBattery's Nearcast to watch batteries across several Macs on your network, keep it around, Juicy doesn't do that (yet).
