Step By Step app for iPhone and iPad
This app is a very simple tool, which helps you to track the progress of your project or tasks. You can see how many percentages left to achieve your goal. By the way, you can not modify your tasks once you have created them.
PS: This is the very first version, and I know that there should be a lot of things could be improved. Therefore, if you have any feedbacks, please let me know. :D
