Best app ever

I was looking for something smart and that can track runtime battery once it’s disconnected from the power and this is app is exactly what I was looking for. It shows asleep time as well as running time. Now I can honestly say that Apple lying about macbook pro battery life because surfing web or watching movies is not letting me run 10 hrs from my brand new 2017 MacBook Pro 15”. Thanks for the app. App also giving results what battery state is and comparison with other users. Very helpful and informative! Other apps I tried didnt even give me close details.

Thank you so much! You are right, the common phrase "up to 10 hours", mentioned in the specifications, really doesn’t tell us anything.

An unobtrusive but extremely helpful battery app-- all the data that I want, right in my menubar: the amound of time I have left on battery, unobtrusively displayed (until I get close to needing a charge, when it turns red), and then, if you click on the icon, you get everything: battery cycles, system battery stats, wear level, time on battery, time battery will die, everything! You can even compare your battery to others, on the internet. Great app.

Great App

Since Apple is so cagey about telling you how much battery life you have left, this app is awesome. Especially since it reveals that the Apple claim that the battery life of the new MacBook Pro is 10 hours is FAR from accurate. More like 4-5ish if you turn the brightness way down?

I do find that the initial estimate of battery life when the battery is full tends to be a little optimistic, but it's still pretty accurate. Great app.

Thank you, I'm glad you enjoyed the app.
