I’m taking off one star because a normally supplied feature (charge history) is actually an in-app purchase type upgrade! I’ of the opinion that in-app purchases should be completely different apps and/or standalone products. No. It is a feature I’d think would be standard on a product that supports tracking battery life. The data presented in a graphical way is already available in Apple OS X and supplied in much greater detail in About The Mac>System Report>Power>Battery Information. Probably not worth the upgrade (certainly not for me). The app is reliable and has otherwise nice features.
