I spent time looking through Mac battery apps to see how each one handles notifications. Here is what each app does, what it costs and where it works best.
I make Battery Beggar, so I have an obvious bias toward my own project. I checked every other app listed here on 4 October 2026 using its official listing or documentation.
macOS shows its own low-battery warning when your charge gets low. Apple includes options for Low Power Mode, Optimized Battery Charging and battery longevity on its Battery settings page.
The operating system does not provide settings to change the alert percentage or pick a custom sound. I could not confirm the exact default warning percentages on Apple pages. If you want earlier alerts, custom sounds or hardware limits, you need a third-party app.
| App | Price | Alerts | Good at |
|---|---|---|---|
| AlDente | Freemium (Pro is 23.99 euros lifetime or 11.49 euros per year) | I found no explicit low-battery notification feature | Limiting charge levels and pausing charging during high heat |
| coconutBattery | Free (Plus price not confirmed) | Custom alerts for battery percentage or remaining time in Plus | Checking battery health for Mac, iPhone and iPad |
| Stats | Free and open source | Not confirmed | Full system monitoring across CPU, GPU, memory and sensors |
| iStat Menus 7 | 11.99 dollars | Customisable rules-based notifications for battery state changes | Detailed menu bar metrics and broad system telemetry |
| BatteryBoi | Free and open source | Not confirmed | Showing time remaining and tracking connected Bluetooth devices |
| Juicy | Free (Juicy Pro Lifetime is 9.99 dollars) | Custom percentage alerts with colors, sounds and screen glow | Visual low-battery alerts and tracking other Apple devices |
| Battery Monitor: Health, Info | Free | Configurable low and full battery alerts | Simple menu bar display with basic alerts and time remaining |
| Battery Beggar | Free (optional 2.99 dollars Percy voice pack) | Spoken or text notifications at 50%, 25%, 15%, 10% and 5% | Humorous personality alerts when your battery drops |
AlDente comes from App House Kitchen and serves as a charge limiter for MacBooks. The basic edition is free, while AlDente Pro costs 23.99 euros for a lifetime license or 11.49 euros per year. Its Heat Protection pauses charging when your battery temperature runs too high. If you need low-battery warnings, I found no explicit low-battery notification feature in the app.
coconutBattery focuses on hardware health. Its free edition shows battery health for your Mac, iPhone and iPad. The Plus edition adds notifications when the Mac battery falls below a chosen percentage or runtime, though I could not confirm the Plus purchase price. It is closed source.
Stats, created by exelban, is a free, open source macOS menu bar monitor released under the MIT license for macOS 12 or newer. It displays readouts for CPU, GPU, memory, disk, network, battery and sensors. Regarding low-battery notification thresholds, I could not confirm them from the README. The issue tracker notes a Battery Notifications setting and a bug where the setting fails to save after a restart.
iStat Menus 7 by Bjango costs 11.99 dollars on the Mac App Store and requires macOS 14 or later. It is a closed source system monitor. Per Bjango, it provides customisable rules-based notifications for battery state changes alongside extensive system telemetry.
BatteryBoi by Joe Barbour is a free, open source menu bar indicator licensed under GPL-3.0. Its README mentions support for macOS 11 to 15, showing remaining time and battery levels for connected Bluetooth peripherals. It includes notifications. I could not confirm its low-battery threshold behavior. I could not confirm if the project is still maintained.
Juicy: Battery Alerts and Health is on the Mac App Store for macOS 15 or later. The core download is free, and Juicy Pro Lifetime is a 9.99 dollars in-app purchase. It triggers alerts at chosen levels such as 3%, 5%, 10% and 20%, paired with adjustable colors, sounds and screen glow. It also tracks AirPods, iPhone and iPad. The developer states that no data is collected.
Battery Monitor: Health, Info by Rocky Sand Studio is a free utility for macOS 10.13 or later. It sits in your menu bar showing percentage and time remaining, with configurable alerts for low and full battery states. The developer claims over 1 million downloads.
Battery Beggar is my own free menu bar utility on the Mac App Store for macOS 13 or later. It gives you spoken or notification alerts whenever the battery crosses 50%, 25%, 15%, 10% and 5%. It includes five personality packs: Dramatic, Passive Aggressive, Stoic, Anxious and Matter of Fact. There is an optional 2.99 dollars in-app purchase for the Percy Voice Pack, featuring Percy speaking his lines in his own recorded voice. Anyone who bought the app before it went free gets Percy free. It collects no data and runs entirely on your Mac. You can turn off reactions in settings to use it as a plain, silent battery monitor. It does not limit charging, and it does not show battery health or cycle counts.
Different utilities solve different problems. Here is how to decide based on your needs.
No. Battery Beggar does not limit charging and does not alter hardware charging behavior. If you want to limit charging to preserve battery life, AlDente is designed for that purpose.
Apple's Battery settings page lists no option to change the warning percentage or alert sound. I could not confirm the exact default warning thresholds from Apple documentation.
Stats (MIT license) and BatteryBoi (GPL-3.0). I could not confirm AlDente's license, and I found no sign that the other apps here are open source.
No. Battery Beggar collects no data, and everything runs locally on your Mac. Juicy also states in its App Store listing that it collects no user data.
Yes. You can turn off the option called Enable personality and reactions in settings. The app will then sit quietly in your menu bar as a standard battery monitor.
Free on the Mac App Store. All five personality packs, notifications and voice mode are included. One optional $2.99 pack (Percy) if you want him.
