Track what you eat,
and how you felt.
In one UK diary.

Log a meal in a couple of taps. Log how you felt after: bloating, gut, energy, mood, sleep. Over a few weeks, the diary shows which foods keep showing up when you feel rubbish.

01 What the diary actually does

One diary,
both sides of the story.

Most apps track one half. Food, or symptoms. Ours holds both, in the same place, so the pattern between them can surface on its own.

i

Log a meal in a couple of taps.

Name, search, barcode, or photograph the plate. The calories, macros, vitamins and additives fill themselves in. Free tier covers up to 25 foods a day.

ii

Log how you felt after.

Bloating, gut, energy, mood, sleep, skin, headache, nausea. Each entry has a severity and a time, so the diary knows what came after which meal. Free tier covers up to 5 reactions.

Bloating, post-lunch Mod
Low energy, 3pm Mild
Headache, evening Mod
iii

Suspected triggers after three weeks.

Once the diary has a few weeks of food + reaction entries, the suspected-triggers view surfaces which foods keep showing up on the days you felt worst. Not a diagnosis. A starting point.

The AI Coach reads what you logged.

The Coach has access to your diary, your reactions, your training, your fasting. Ask about a meal, a week or a goal and the answer references your own data. Same app, same diary, no copy-paste.

02 A week of food and reactions

One week.
One pattern.

Here's a worked example of what the diary looks like across seven days. A handful of meals a day, a handful of reactions, and what shows up when the diary lines them up.

The diary does the joining-up for you.

Reactions log against the meal that came before them. The pattern view groups by food. Over a few weeks, the same suspects keep showing up. That's the data you take to a GP or dietitian appointment instead of trying to remember.

i. Mon, Wed, Fri: chicken tikka masala, then bloating that evening. Three meals, three reactions.
ii. Tue, Sat: lighter dinner. No bloating. Reaction log is blank.
iii. Suspected triggers surfaces "creamy curry sauce" at the top of the list. Three for three across the week.
iv. You take the diary summary to your GP. "Here's the food, here's the reaction, here's the count."
03 Where we stop, and where the GP starts

We track.
Your GP diagnoses.

NutraSafe is a tracking and awareness tool, not a clinician. We don't tell you to cut a food out, we don't say what's wrong, we don't prescribe. We give you something concrete instead of trying to recall what you ate last Tuesday.

What the GP gets when you walk in

Bring the diary summary. It's a list of meals, reactions, severities and the count of how often each food showed up before each symptom. A 10-minute appointment goes a lot further when the GP isn't reverse-engineering your week from memory.

The same goes for a dietitian, a gastroenterologist, or a nutritionist. The diary is evidence, not a conclusion. The clinician decides what to do with it.

We never tell you to eliminate a food. We never tell you it's an allergy or an intolerance. That call belongs to a clinician, and the diary helps them make it.

05 Questions people ask

Food & reaction
FAQ.

The questions we get from people scanning a packet in the aisle and wondering whether the app does the second half too.

Can I track both food and reactions in one app?

Yes. You log meals by name, search, barcode or photo. You log reactions (bloating, gut, energy, mood, sleep, skin, headache, nausea) in the same diary. They sit side by side, which is how the pattern surfaces.

How long until a pattern shows up?

Most people see something within one to two weeks of consistent logging. After three to four weeks the suspected-triggers view (Pro) gets useful, because the diary has enough data to spot which foods keep showing up when you feel rubbish.

Is it free?

The download is free. The free tier lets you log up to 25 foods a day and up to 5 reactions, with the barcode scanner and the additive flag. NutraSafe Pro is £3.99 a month or £34.99 a year and lifts both caps, adds the AI Coach, suspected triggers, workouts, fasting and the AI meal scan.

Does it replace a GP or dietitian?

No. We track and surface. We don't diagnose, we don't prescribe. The diary gives you something concrete to take to your GP or dietitian instead of trying to remember what you ate last Tuesday.

What reactions can I log?

Bloating, gut, energy, mood, sleep, skin, headache, nausea. Each entry has a severity (mild, moderate, severe) and a time relative to the meal it followed.

Can I export the diary?

Yes. The app generates a summary of your food and reaction history that you can take to a GP, dietitian or gastroenterologist appointment. More useful than a 10-minute conversation from memory.

Does it work with UK supermarket foods?

Yes. The barcode scanner reads any UK pack that exists in the food databases. Tesco, Sainsbury's, Asda, Morrisons, Aldi, Lidl, Waitrose, Co-op and M&S own-brands plus branded products are all covered.
