Carbs, protein and fat is what you came for. We also break out the saturated fat, the free sugars, the fibre and the salt, because the UK traffic-light labels do. Same diary, one tap.
Straight off the UK nutrition panel. Pick the portion, hit add, the macros scale.
Set protein, carbs and fat once. The diary rolls the day's total against the target and shows you where the gap is.
UK traffic-light territory. We break them out alongside the headline macros so you can see where the day is leaning.
Lift, set a higher protein target. Same diary as your sets and reps. Apple Watch syncs the session and the burn.
A hit-your-macros day can still leave you short on vitamin D or folate. Pro adds 14 vitamins and 13 minerals against the UK NRV.
We read any UK barcode (GTIN/EAN). Branded or own-brand. Same numbers as on the pack.
These are the figures the NHS Eatwell guide and SACN review actually use. Set your target once. Log against it.
SACN's 2011 dietary reference value for the average adult. Lifters and athletes typically aim higher (1.6 to 2.2g/kg).
NHS Eatwell guide. About 70g for a 2,000 kcal day. We surface the % live as you log.
SACN saturated fats and health (2019). Around 20g for women, 30g for men on a typical day.
SACN carbohydrates and health (2015). Around 30g a day. The diary breaks free sugar out from total carbs.
NHS guidance. Roughly 2.4g sodium. We split salt from sodium when the label gives the gram figure.
SACN carbohydrates and health (2015). The average UK adult sits around 19g; the diary shows the gap as you log.
A typical lifter's day: porridge + Greek yoghurt + a Tesco sandwich + a salmon dinner + a whey shake. Here's the split we'd show in the diary.
The diary keeps a running protein bar at the top, with carbs and fat below it. Tap a number to see which food each gram came from. Tap the SACN line to see the cap.

A macro tracker logs the three energy-providing nutrients in your food (carbohydrates, protein and fat) and adds them up across the day. We pull the figures straight from the UK nutrition panel on whatever you scan or search, so the numbers match the labels you actually buy.
Three ways. Scan a UK barcode (any GTIN or EAN, the same format every UK supermarket uses). Search our food database by name. Or photograph a plate with our AI meal scan on NutraSafe Pro. Pick a portion, hit add, and your daily carbs, protein and fat update in real time.
The app is free to download. The free tier logs up to 25 foods a day with full carb, protein and fat tracking, scans UK barcodes for additives, and lets you log up to 5 reactions. NutraSafe Pro is £3.99/month or £34.99/year on iOS for unlimited logs, vitamins and minerals against UK NRVs, AI Coach, AI meal scan, allergen warning detail, fasting, workouts and suspected triggers.
The NHS Eatwell baseline is fat under 35% of energy, saturated fat under 11%, free sugars under 5%, and around 0.75g of protein per kg of body weight a day for the average adult (higher if you train). The remainder is carbs. Your own target depends on weight, training and goals. Set it once, log against it.
Macros tell you about energy. Micronutrients tell you what is actually missing. The UK National Diet and Nutrition Survey 2019 to 2023 (gov.uk, June 2025) found 18% of UK adults had low vitamin D status, and 83% of women of childbearing age were below the folate threshold. You can hit your macro split every day and still be short on those nutrients. Vitamin and mineral tracking against UK NRVs is a NutraSafe Pro feature.
Yes. We read any UK GTIN or EAN, the same barcode format used across every UK supermarket, so anything with a barcode you can buy here looks up the same way. We don't have per-retailer integrations; the database is one global barcode lookup.
