Hit your protein floor.
Then beat it.
Gram Slam gives you a daily protein floor sized to your body, training and life stage, and makes logging one tap. No calorie counting, no account.
A floor, not a ceiling
Answer a few questions and get a floor with a one-line reason. Reach it and the day is won; go further for bonus grams, up to a sensible cap.
One tap to log
Your usuals sit on Today, in real portions: a scoop, a tub of yogurt, three eggs, a palm of chicken. Undo is always one tap away.
Just type it
"Two eggs, a scoop of whey and a protein bar." Gram Slam reads it on your iPhone; the grams come from its food list.
What to eat next
Three ideas that fit what's left today, your diet and the time of day. Built for low-appetite days too.
Apple Health, widgets, Siri
Protein you log goes to Apple Health. Log from the Home Screen, Lock Screen, Control Center or Siri.
Kind by design
A forgiving streak with rest days, no red failure screens, and a gentle mode if you'd rather not chase numbers.
Our privacy promise
No account. No ads. No analytics. No tracking.
Your log, your foods and your body numbers stay on your iPhone and in Apple Health. The AI features run on your device with Apple Intelligence. The only thing that ever leaves your phone is a barcode number you scan, sent to Open Food Facts to look the product up. Read the privacy policy.
Gram Slam is for adults. It provides general wellness guidance, not medical advice. If you have kidney disease or another health condition, are pregnant, or are under a clinician's care, ask your doctor or dietitian how much protein is right for you.
