It's handy to design and simulate your rocket to know it's stable and of course to hit those important altitude and flight time requirements for UKROC. All of these software let you simulate your rockets flight to work out how to adjust your design to try and win.
Of course it's not essential you use software, you can create your designs from a bit of trial and error to tune in on the right settings too.
