Most nutrition content online has no author. It's produced at volume, cites studies it hasn't read, and nobody's name is attached to it. That's a reasonable reason not to trust it. So here is who writes this site, what I actually know, and where the limits are.
Rekkon is a voice-first AI nutrition coach for iPhone, built in Australia by one person. I'm Daniel Treacy — a software engineer, not a dietitian. I lost 50kg of fat and built 10kg of muscle over several years without counting calories, and I built the food-logging tool I wanted during it. Everything here is general nutrition information sourced from peer-reviewed research, and none of it is medical advice.
Who I am
I'm Daniel Treacy. I build software on the Sunshine Coast in Queensland, Australia. Before this I worked in delivery management and agile coaching at Accenture; back surgery ended that chapter, and I rebuilt my fitness through running — I'm past 600 consecutive days at the time of writing, and I race across South East Queensland.
Rekkon is the fourth attempt at the same problem. The first three didn't work, for reasons I've written about. This one launched on the App Store in April 2026.
What I am and am not qualified to say
I am not a dietitian, a doctor, or a nutrition scientist. I have no clinical credentials, and I'm not going to imply otherwise.
What I do have is lived experience of the thing this site is about — a large, sustained body-composition change and the years of failed attempts before it — plus the engineering background to read a paper, check what it actually measured, and notice when a widely-repeated number doesn't trace back to anything.
That combination is useful for some things and useless for others. It's useful for explaining why calorie tracking fails at the level of habit and friction, what portion estimation research actually found, and how the numbers in popular apps are produced. It is not a substitute for individual clinical advice, and I flag that on every article rather than burying it.
How the articles here are written
Every article on this site follows the same rules:
- Named sources, not vague appeals. When a claim comes from research, the journal or cohort is named in the text — the British Journal of Nutrition on hand-portion accuracy, the American Journal of Clinical Nutrition on protein and satiety, the National Weight Control Registry on maintenance, the STEP 1 trial extension on GLP-1 withdrawal.
- Ranges, not false precision. Where the evidence gives a range, the article gives the range. "1.2 to 1.6g per kilogram" is honest; a single number would not be.
- The product is named as a product. Rekkon appears in these articles because I built it and it's relevant. It's marked as what it is, not smuggled in as a neutral recommendation.
- Corrections are dated. When an article changes materially, the updated date on it changes.
My commercial interest, stated plainly
Rekkon is a paid subscription app and I make money if you subscribe. That's a real conflict of interest and you should read everything here with it in mind. Two things follow from it that I try to hold to: the free calculators require no signup and no email, and the articles are written to be useful whether or not you ever download the app. Several of them explicitly tell you that a cheaper or free approach will work fine.
What Rekkon actually does
You hold a button and say what you ate — "chicken wrap with avocado and a flat white" — and Rekkon estimates the calories and macros, no barcode and no database search. Over weeks it builds a picture of your eating patterns and coaches the specific adjustments that would matter for you. Estimates are directional rather than laboratory-grade; if you know exact numbers you can say them, and every meal is editable.
It's iPhone-only, there's a seven-day free trial with no credit card required, and it's built by one person in Australia.
Medical disclaimer
Nothing on this site or in the Rekkon app is medical advice, diagnosis, or treatment, and none of it is a substitute for care from a qualified health professional. If you have a health condition, are pregnant or breastfeeding, take medication, have a history of disordered eating, or are under 18, talk to a doctor or an Accredited Practising Dietitian before changing how you eat. If you're currently on a GLP-1 medication, decisions about starting or stopping it belong with your prescriber.
Contact and corrections
If something here is wrong, I want to know. Corrections, questions, and disagreements are welcome — the contact link in the footer reaches me directly, not a support queue.
