Hello, I am new to project planning/management. I know noting about these things. I recall that when Microsoft Project for Mac came out many years ago, I played with it and found it useless. I am looking for software (iOS/Mac/both) that allows me to keep track of the progress of my project(s), is easy to use, has nice graphical user interface, not so expensive or free, better have both iOS and Mac OS version. Don't need collaboration. Any suggestion?
