Watts is a MacBook® battery management and calibration assistant tool.
It's a menu bar app that, 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 for your needs, and even postponed if you want. Calibration data is automatically logged, so you can see the history of your battery status.

- Watts looks similar to the Mac OS® battery icon menu, and provides some extra options like vertical battery icon and more.

- Watts monitors you battery status constantly and provides you with information and notifications to help you using your MacBook® battery properly. Watts provides detailed information on the battery capacity, charge cycles and health. It also stores your battery data regularly, so you can check its evolution during time.

- Watts provides detailed in-app help, everything is clearly explained!

- Works on any MacBook® model (MacBook®, MacBook Air®, MacBook Pro®)

- Supports Retina® display

- Only for Mac OS® 10.11 "El Capitan" or later


Release Notes:

Minor version fixing two problems.
The algorithm was not behaving when we were switching on and off the computer in the last steps. Not anymore.
Also when we setting it to sleep and awake in the very last step without plugging it was jumping to the first step. That should not happen anymore.
We hope we will have new things next time!

Review by App~Guru

Worked Great on Snow Leopard, but won't work on Lion!!!! Update it Already Dev!!! - When I had Snow Leopard this app was great to keep my Macbook Pro's Battery "calibrated"(basically doing a full battery drain once a month", but since I've installed Lion(Since its release in July) I can't get this app to work. The app will "load" on boot, but the menubar icon is no longer there, rendering this app useless since you can't control it or check "calibration" or get reminders without the menubar icon. I gave the Developer several months to come on board with Lion, but considering it's almost 5 months since Lion's release and no update has been provided this app is now useless and the Dev seems not to care. DON"T BUY THIS APP IF YOU HAVE LION!!! IT WON"T WORK!!!! DEV UPDATE THE APP OR REMOVE IT!!!!!!!!!!!
