Greetings. Thanks for your interest in FruitJuice. Our main goal is to make sure you use your machine on battery sufficiently. There are other benefits as well: notifications with certain time or percent remaining as well as full usage history. To address concerns similar to yours, we are in the process of putting together a 2 week demo for direct download from our website so you can actually try it before you decide to buy it. Feel free to email us directly at
support@fruitjuiceapp.com or by using our Support link on our website if you have furher questions. Cheers. - j e f f
