Most calorie counters stop at the number. We log the kcal and macros, then read every additive on the pack and tell you what each one actually is. The number, and what's behind it.

Most calorie counters give you a kcal total and a macro split. We give you that, plus the ingredients, the vitamins, and what the additives actually are. All in the same diary, so the numbers and the labels live next to each other.
Type a name, scan the barcode, or take a photo of the whole plate. The kcal and the carbs, protein and fat fill themselves in from the UK label.
Every additive on the pack, written like a normal person would describe it, with the regulator behind every flag.
Carbs, protein and fat per food roll into your day. Set a target, see the split, see where the kcal came from.
Sets, reps and weight on the workout side. Apple Watch syncs the kcal back into your day, so the in and the out sit next to each other.
As you log, the diary builds your vitamin and mineral totals against the UK NRV, so you can see where the week is short.
Tag energy, mood, gut and skin after a meal. Over time the diary lines reactions up against foods you logged, so you've got something solid to take to your GP.
We read any UK barcode (GTIN/EAN), so a Tesco own-brand sandwich and a tin of Heinz look up the same way. Same numbers as on the label.
Most of the calorie counter market gives you a number. Here is what we give you when you scan one common UK shop sandwich.
The nutrition panel comes straight from the pack. The ingredient list comes straight from the pack. We just read both, and tell you what each ingredient actually is.
These are the things waiting for you the moment you download the app. No watered-down trial.
Type, search or barcode. Branded or own-brand. Same database as Pro, just capped at 25 entries per day.
14 vitamins and 13 minerals against the UK NRV. Daily, weekly and monthly. NutraSafe Pro.
Every E-number we recognise on a UK pack, written in plain English. Where published evidence exists, the source is on the line.
If a UK barcode exists in the food databases, the scanner reads it. Branded or own-brand.
What it is, how to do it, and what the NHS and SACN say. The bits worth knowing before you start.
A calorie, or kcal, is a unit of energy. Counting them means logging what you eat and drink so you can see the day's total. The value is awareness. Most people are surprised that a shop meal deal can reach 800 kcal, or that a bowl of granola can sit near 450 kcal before the milk goes on. Once you can see it, you can change what you eat without giving up the foods you like.
The method is simple. The accuracy comes from the habits around it.
In the app you scan the barcode or search the food, and the kcal and macros fill in from the UK label.
The NHS uses around 2,000 kcal a day for women and 2,500 kcal for men as a general reference. Those figures come from SACN, the UK's nutrition advisory committee. Your own number depends on your age, weight, height and how active you are, so the averages are only a starting point. A TDEE calculator gets you closer to a personal figure.
To lose weight, you take in fewer calories than you use. For steady loss of about 0.5kg a week, the NHS suggests eating roughly 500 to 600 kcal a day below your maintenance level. Slower is usually easier to keep up than a crash diet. Weigh yourself weekly rather than daily, because water and food in the gut move the scales around from one day to the next. If you are pregnant, breastfeeding or managing a health condition, speak to your GP or a dietitian before cutting calories.
A calorie total tells you how much energy is in a food. It tells you nothing about what is in it. That is the gap we built NutraSafe to fill: as you log, the same diary reads the ingredient list and puts every additive into plain English, with the regulator behind each flag. So you can watch the kcal and see what you are eating at the same time.
Answers sourced to NHS, FSA and SACN, with the regulator named where it matters.
Work out your TDEE (total daily energy expenditure), aim for a 300 to 500 kcal deficit a day, log everything you eat, weigh portions where you can, and check progress weekly rather than daily. We do the per-food number for you once you scan or search.
NHS guidance gives an average daily reference of 2,000 kcal for women and 2,500 kcal for men. Your actual target depends on age, weight, activity and goal. Use a TDEE calculator to set yours, then log against it.
Our free tier logs up to 25 foods a day, scans UK barcodes, flags additives we recognise, and lets you log up to 5 reactions. NutraSafe Pro is £3.99/month or £34.99/year on iOS for unlimited food and reaction logs, vitamins and minerals against UK NRVs, AI meal scan, AI Coach, workouts, fasting and suspected triggers.
UK food labels are accurate within 20% by law. Accuracy gets better if you weigh portions, log straight after eating, and use barcode lookups rather than guessing. Most people underestimate by 20 to 40% when they eyeball it.
No. NHS Better Health frames calorie counting as a learning tool. Most people count tightly for a few months to build a sense of portion sizes and calorie density, then check in occasionally. The awareness sticks even when the logging stops.
A single day doesn't undo a week. The NHS frames weight management around weekly averages because day-to-day eating naturally varies. A pattern of consistent overshoot across multiple weeks is what changes the trend, not one heavier dinner.
It depends how you set your target. If your daily figure already assumes your usual activity, eating gym calories back on top can wipe out your deficit, and fitness trackers tend to overestimate the burn. Many people log exercise to see it, but eat to their fixed daily target rather than adding the burn back.
Calories decide whether you gain, lose or maintain weight. Macros, meaning protein, carbs and fat, shape how you feel and, with enough protein, how much of any loss is fat rather than muscle. Counting calories is the simpler place to start. Tracking macros is the step up once the calorie habit is in place, and the app shows you both at once.
Your maintenance level is the number of calories that keeps your weight steady, also called your TDEE. The NHS averages of 2,000 kcal for women and 2,500 kcal for men are a rough guide, but your own figure depends on your size and how active you are. A TDEE calculator gives you a closer estimate to log against.
The usual reasons are underestimating what you eat, overestimating what you burn, and water retention hiding fat loss on the scales. Labels are only accurate within 20%, and unweighed portions add more error. Weigh your food for a week, weigh yourself on the same day each week, and watch the monthly trend. If the scales genuinely will not move after several weeks of careful logging, speak to your GP.
Large food businesses in England have had to show calories on menus since 2022, so for those you can log the figure straight off. For independents, search a similar dish or build it from its parts and accept the number is an estimate. Logging an approximate meal is more useful than logging nothing.
Yes. Many people lose weight by managing portions, cutting back on high-calorie drinks and snacks, and filling up on vegetables, protein and fibre. The NHS Eatwell Guide is built around this. Counting calories just makes the awareness sharper, which is why people often use it for a while rather than forever.
Yes, that is what NutraSafe does. We log your calories and macros like any tracker, then read the ingredient list on the same food, so the kcal and what is in the pack sit side by side. Free up to 25 foods a day, Pro £3.99/month on iOS.
Scan a UK barcode and we list every additive on the pack in plain English, with the regulator behind each flag. The library covers more than 480 E-numbers, so you can see what an additive is without reading a chemistry page. Barcode scanning and additive flags are on the free tier.
Yes. As you log food, we build your totals for 14 vitamins and 13 minerals against the UK NRV, across the day, week and month, so you can see where you are short. Vitamin and mineral tracking is part of NutraSafe Pro.
We read the ingredient list and flag the additives on each food you log, which is what marks a product out as ultra-processed. Over time you can see how much of your week comes from heavily processed food. Our ultra-processed food scanner goes into this in more detail.
Yes. We read any UK barcode, GTIN or EAN, and pull the nutrition panel and the full ingredient list off the label, then explain each additive. Branded or own-brand, from the big UK supermarkets.
Yes, that is the point of NutraSafe. Log a food once and you get the calories and macros against your target, plus every additive on the same pack explained in plain English. One scan, all of it, in the same diary.
