A macOS app that displays battery status for non-Apple Bluetooth headsets via system-level Bluetooth monitoring.
Akku is an experimental macOS application that monitors and displays battery levels for Bluetooth headsets, which macOS does not natively support for non-Apple accessories. It solves the problem of users not knowing when their wireless headset battery is low by intercepting Bluetooth communication data to extract battery status information. The app provides a menu bar icon and optional notifications for low battery alerts.
Mac users who rely on Bluetooth headsets (especially non-Apple brands) and want to monitor battery levels directly from their desktop. This includes professionals, students, or anyone using wireless audio devices with macOS.
Developers choose Akku because it uniquely addresses a macOS limitation through system-level Bluetooth monitoring, offering a lightweight, secure solution with broad device compatibility. Its use of privileged helpers and code signing ensures safe access to kernel data without compromising system integrity.
Experimental bluetooth headset battery monitoring application for MacOS
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Works with any Bluetooth headset conforming to Apple's specifications, as stated in the README, typically those that show battery status on iPhones or Android devices.
Uses a privileged helper tool with code signing and XPC communication to safely access kernel-level Bluetooth data without exposing raw system data, ensuring secure operation.
Provides optional alerts when headset battery is low, directly addressing the gap in macOS functionality for non-Apple accessories.
Displays battery percentage in the macOS menu bar with a simple icon, offering a non-intrusive way to monitor status as highlighted in the features.
The project is no longer maintained and will not work on macOS Monterey or later, as explicitly warned in the README's important notice.
Requires users to grant root permissions for Bluetooth data monitoring, which can be a security concern and a barrier for privacy-conscious individuals.
Development has stopped, so there are no plans for bug fixes, compatibility updates, or feature enhancements, limiting long-term usability.
Device compatibility issues require users to follow specific guides and provide technical data, as mentioned in the FAQ, making it less user-friendly for non-technical users.
