The Bar is designed to offer a practical way to use your iPhone or iPod touch to monitor your processes, with the following features: - Simple and intuitive interface. - Data persistence, which means that at each stage your data is stored. Even a possible incoming call does not interrupt the process. You can also exit the application and return at any moment; the process will continue as if it was running in the background.* - Recalibration ensures that even processes that do not have a constant speed may be updated. - Help information on all screens with detailed step-by-step instructions of each stage. *The application does not run in the background, but due to persistent processes, it can update the data immediately upon restarting the application.
