For anyone tracking macros: cutting, bulking or maintaining
Snap a photo.
Know your macros.
Take a photo of your plate, type what you ate, or just say it. GRAMS uses AI to work out the protein, carbs, fat and calories, and tracks them against targets built for your body and your goal.
The breakdown ✨ PRO
See exactly what's on your plate
Snap a photo and AI lists every item it finds, with grams, protein, carbs, fat and calories for each, plus a note when something like cooking oil could change the total.
- A confidence level on every item
- Change any number, or add and remove items
- Cooked with oil or butter? Add it in one tap
- Tag it breakfast, lunch, dinner or snack, then confirm
Pantry, shopping & recipes
Cook from what you already have
Check off what's in your kitchen and keep a shopping list that fills your pantry as you shop, and share it with anyone in one tap. Scan a product at home or in the store to add it. Then ask “What can I make?” for recipe ideas sized to what's left in your day.
- Pantry and shopping list are free
- Warns you when a scanned product contains one of your allergens
- Recipe ideas with step-by-step instructions ✨ PRO
How it works
Three steps, then it's a habit
Set your targets
Enter your weight, height, age and goal. GRAMS works out your daily calories and macros in about 30 seconds.
Log a meal your way
Snap your plate (✨ PRO), type “two eggs and toast,” or say it out loud. AI fills in the macros, and you can adjust anything before saving.
Watch your day add up
Rings fill as you eat. Every meal lands in History with its photo, tagged breakfast, lunch, dinner or snack. Eat it again? Tap Log again.
Weekly check-in✨ PRO
Targets that learn from your results
Each week GRAMS compares what you logged with how your weight actually moved, then suggests calories that fit your real results. Your carbs-to-fat balance is kept, and nothing changes until you tap Apply.
- Leaves out half-logged days automatically
- Never moves more than 10% in a week
- One tap to undo
AI coach
Ask what to eat next
Short on protein with a few hours left in the day? Ask your coach. It looks at what you've already eaten and your targets, then suggests specific foods and amounts to close the gap.
Weight
A trend line that ignores the daily noise
Water weight swings the scale every day. GRAMS smooths your weigh-ins into a trend so you can see which way you're really heading.
- Your start weight, target and how far to go
- An estimated date for reaching your goal
- Pounds or kilograms
Your week
See the whole week at a glance
Protein, carbs, fat and calories for each day, drawn against your targets. Ask for a weekly summary and AI tells you what went well and what to adjust.
Streaks
Build the habit one day at a time
Log each day to grow your streak. One missed day won't break it; two in a row will. Badges unlock at 7, 14, 30, 60, 100 and 365 days.
Scan
Scan it, log it, list it
Barcode scans log in one tap, straight from the food database with no AI guessing. You get per-serving numbers, a Nutri-Score, and a warning if it contains something on your allergy list, plus a button to save it to your shopping list.
