I used the ability to enter decimals for reps (i.e. 10.3) to note what strength resistance band i had used when I did 10 reps. Then i could compare the next time I did the program and try to better myself or be sure I wasn't slacking. Several exercises don't have a field for weight and others only allow a time. Even the time ones don't allow for noting how many reps in the time were completed. The overall workout notes from a past session are not easily accessible and even if they were, its not a great place to note exercise specific details.
