nutrition, measured — not guessed
Know your food.
All 34 nutrients of it.
Most trackers stop at calories. Yolo evaluates 34 nutrients — vitamins, minerals, fatty acids and glycemic load — against reference values personalised to you, and turns them into one score you can act on.
how the score works
From plate to panel in three steps.
Log what you eat
Snap a photo, scan a barcode, describe your meal by voice, or search the database. Logging takes seconds, not minutes.
Measure against your references
Every food is resolved to lab-analysed nutrient values, then compared with science-based reference intakes personalised to your age, sex, weight and activity.
Read one honest number
34 nutrient evaluations collapse into a single 0–100 score — with the full panel one tap away when you want the detail.
beyond calorie counting
Built for people who want the whole picture.
Yolo connects what you eat with how your body responds — activity, sleep, heart rate and weight — so patterns stop being guesses.
AI food recognition
Photograph your plate and Yolo identifies the foods and portions. Correct anything with a tap.
Apple Health & Health Connect
Weight, sleep, heart rate, HRV and activity flow in automatically — with your permission, and only that.
