Compare
Each of these does its own job well. The comparison worth making is what happens at the seams between them.
A food diary knows what you ate. A training log knows what you lifted. A strap knows how you slept. Each answer is correct and none of them decides what today should look like, because that decision needs all three at once.
The pages below say plainly what each product covers, where it is the better choice, and where NAFA is.
MyFitnessPal is a food diary: it counts what you eat against a calorie and macro target. NAFA logs food as one input among several, then reads it together with your training, sleep, and body measurements and tells you what the combined picture means today.
WHOOP is a sensor: a strap that measures recovery, sleep, and strain continuously. NAFA is software that reads those signals alongside your training log and food intake. The two are not alternatives — NAFA connects to WHOOP and uses its recovery data as an input.
Hevy is a training log: it records sets, reps, and load, and it does that cleanly. NAFA records the same things, then reads them against your food, sleep, and body measurements and tells you what the combination means for today.
