Apple Juice is a free, open-source Mac menu-bar utility that gives you granular, at-a-glance visibility into your MacBook's battery — far beyond what macOS shows by default.
What is Apple Juice?
Apple Juice is a lightweight menu-bar application for macOS that surfaces detailed battery telemetry — charge percentage, estimated time to full charge or full drain, current power draw, cycle count, and battery health — directly from your menu bar. It is open-source (MIT-licensed), maintained on GitHub, and free to download with no IAP or subscription.
The project was born out of frustration with the native macOS battery indicator, which tells you almost nothing useful without diving into System Information. Apple Juice puts the numbers that matter one click away.
What does Apple Juice do best?
Apple Juice excels at giving power users a quick, honest read on battery health without opening a single System Preferences panel. The menu-bar icon itself can show a live percentage or a visual gauge, and the dropdown expands to a compact but information-dense summary: time remaining, time to charge, capacity relative to design capacity, and the current cycle count.
I particularly appreciate the health indicator. On an aging MacBook, knowing your battery is down to 84 % of original capacity — and watching that figure move — is exactly the kind of data that informs a real purchasing decision. Activity Monitor doesn't show you that inline; Apple Juice does.
Notifications are another quiet strength. You can set charge thresholds — alert me when the battery drops below 20 %, or when it hits 80 % so I don't over-charge a lithium pack — and Apple Juice will fire a native macOS notification without nagging you otherwise.
Is Apple Juice free?
Yes, Apple Juice is completely free. The source code lives on GitHub under an MIT licence, meaning you can inspect every line, fork it, and compile it yourself if you prefer not to use a pre-built binary. There is no freemium tier, no donation nag screen, and no telemetry.
Who should use Apple Juice?
Apple Juice is the right tool for anyone who spends serious hours untethered from a power socket. Developers on long flights, writers in coffee shops, and road-warrior consultants who need to budget their remaining power across meetings will all find the time-remaining estimate more reliable than macOS's own (often wildly optimistic) guess.
It is also invaluable if you are managing a fleet of MacBooks — your own included — and want to track battery degradation over time without paying for a full device-management suite. The cycle count alone is worth the install on any machine more than a year old.
If you rarely leave your desk and your MacBook lives permanently plugged in, Apple Juice won't add much to your workflow. In that scenario, the native percentage display is probably sufficient.
What are the best Apple Juice alternatives?
The closest alternative is Battery Indicator by Max Zeryck, which offers a similar menu-bar percentage display with time estimates. For a more feature-rich paid option, coconutBattery adds historical charge graphs and iOS device support — genuinely useful if you want to track degradation week-over-week. iStat Menus bundles battery detail inside a comprehensive system monitor; it's excellent but costs money and adds more overhead than most people need just for battery data.
Apple Juice sits in the sweet spot: more information than the built-in indicator, zero cost, and none of the bloat of a full system-monitoring suite.
How does Apple Juice compare to coconutBattery?
coconutBattery is the gold standard for deep battery diagnostics — it renders charge history charts, tracks design capacity versus current capacity over weeks, and connects to iOS devices over USB. If you are diagnosing a battery-replacement question or tracking long-term health trends, coconutBattery is hard to beat.
Apple Juice is the better daily driver. It has a smaller footprint, lives unobtrusively in the menu bar, and loads the numbers you check twenty times a day — percentage, time remaining, current wattage — instantly. I run both: Apple Juice for the quick glance, coconutBattery every few weeks to log capacity trends. They complement each other rather than compete.
