Watts provides MacBook battery management and calibration assistance. It's a menu-bar app which, apart from the usual battery information (power source used, current battery charge and remaining time), provides advanced data to obtain the maximum performance of your MacBook battery.

Your battery needs to be calibrated from time to time to keep the onscreen battery time and percent display accurate, and to keep the battery operating at maximum efficiency. Watts features an intuitive calibration assistant that will guide you through the process of calibrating your battery. The calibration scheduling can be adjusted
