SlimmerKiwi is spot on with the answer.
The choice is yours.
Either you track or not. However, those who do, find it a learning experience, and have a better idea of where their danger spots are, and where they need to improve regarding nutritional balance.
I, too, do not use the meals suggested by SP. I make my own.
I add ingredients to my favourites - mostly those I've put in myself, but for basic ones, I use the SP entries (like vegetables, fruits, etc.). The reason for entering my own is that I like to enter by weight or volume, rather than "one serving". To me, that is a meaningless amount - because I have no idea what someone else considers a serving size.
So, now that they are in my favourites (yes, it took a while to get it the way I needed it to look), they are easily added.
Additionally, I've put in recipes that I use frequently, and put them in my recipe box, so I can just choose that as an entry on my tracker.
