In 2016, Apple removed "time remaining" from macOS. Their reason? The estimates "varied too much." Their solution was less information. TurtleBar brings it back. See "3:47 PM" or "2h 34m" right in your menu bar—the exact time your battery runs out. No more guessing if you'll make it through your meeting, your flight, or your workday. Lightweight. Native Swift. Works on Apple Silicon.
TurtleBar's real-time time-remaining display adjusts instantly as apps open or close, showing users exactly how much battery each action costs. This awareness helps users decide whether to close Chrome, switch to Safari, or enable power saving before battery becomes critical.
TurtleBar auto-toggles Low Power Mode when battery hits a custom threshold (e.g., 40%), which is earlier than most users manually enable it at 10-15%. This saves 1-2 additional hours of battery life per charge compared to manual toggling.
TurtleBar displays exact time remaining (e.g., '3:47 PM' or '2h 34m') in the menu bar, updated in real-time based on actual workload. This replaces Apple's removed time-remaining feature and lets users plan around battery depletion instead of guessing from percentages.
TurtleBar's per-app power rules let users set automatic Low Power Mode activation when specific apps run, regardless of battery percentage. This targets battery drain from known heavy consumers while keeping performance normal for lightweight tasks.
TurtleBar uses less than 1% CPU, is built in native macOS (not Electron), costs $1.99 one-time with lifetime updates, and includes no tracking. This appeals to users wanting minimal system impact and no recurring fees.
