ConjureBunny Software has released PowerUp 1.0 (http://macte.ch/879QD), a task manager designed to help you stay focused. It requires Mac OS X 10.6.6 or higher on an Intel-based Mac. It’s available for US$20 for a single-user license.
PowerUp is a step-by-step task manager with a built-in progress tracker. You flesh out big or complex tasks with unlimited smaller tasks. It helps you focus on individual steps necessary to accomplish larger tasks, and provides positive reinforcement along the way via a huge progress bar at the top of the window.
PowerUp is developed from the ground up using the modern 64-bit Cocoa code. It’s also optimized for Mac OS X 10.6 (“Snow Leopard”) and Mac OS X 10.7 (“Lion”).
