Almost perfect. Just missing PRs for each rep range. It tracks PR for most weight for each exercise but would be great if it could do it for each rep range. Example. Sometimes I do sets of 3,5,7,10 reps. It would be great to have max for 3 reps, 5reps, etc. to save time doing calculations, guessing, or estimating the weight I should use for each workout. Definitely recommend tho
