Want to take care of your device and maintain your battery life?

- the same power charging chime sound effect you are familiar with on your iPhone, indicating when the battery is charging when the cable is unplugged, the battery is charged to your preset percentage, and the battery is drained to your preset warning percentage

Great job

This application is what I wanted! I always hated it when I was doing something in full screen, and I forget to check the battery, and then it dies on me. With this, I can finally know when it reaches 20% so I can plug it in and when it reaches 100%! Keep up the good work!

Very good battery app; could be the best if...

I'm always on the lookout for menu bar apps (menulings) with the smallest foot print. This app takes up even less menu bar real estate than the incumbent Battery Monitor which has unseated Apple's own underwhelming Battery menuling on my MBP. It also offers system Notifications when battery level falls below a definable threshold, which is a Must-have for battery apps, IMO. What makes this app less than perfect (and not quite ready to replace Battery Monitor yet) is the fact it doesn't report the Design Capacity and Current Capacity of the battery, like the latter does, hence my current four-star rating. Otherwise, it's a very good app for monitoring your current battery level, if you don't care about the capacity info. It has the potential to be the No. 1 battery menuling.
