This app is a great app for increasing battery life. I just got a new MacBook Air 13 inch and I want it to last a while. I have a similiar app on my iPhone, so I decided to get this app on my mac. This app shows how long your MacBook Battery will last and the health. My MacBook Health is now 103% thanks to this app. I also reccomend buying the charging history feature, it is really helpful. I would give it 5 stars, but I have one suggestion. This is a charging app. When I plug in my MacBook Air, I want to know how long it will take to charge. Really great app.
