Built for patients.
Engineered for trust.
CannaLog is a UK medical cannabis tracking platform designed and built by a single founder — an ex-military infrastructure engineer and a UK medical cannabis patient. It exists because UK patients deserved something better than a spreadsheet.
The UK has had legal medical cannabis since 2018.
The tools haven't kept up.
If you're on a UK cannabis prescription, you already know the drill. Every consultation, your specialist asks how it's working. What helped, what didn't, how much you took, which strain, which terpenes. And almost everyone answers the same way — "I think it was about…"
That's not a patient problem. That's a tooling problem. Spreadsheets aren't built for this. Generic symptom trackers don't understand THC, CBD, terpene ratios, or the difference between a Mighty+ at 185°C and a Volcano at 190°C. And no-one's going to share their intimate health records with an app that sells data to advertisers.
CannaLog is the answer to that. A properly engineered, UK-hosted, clinic-aware platform that turns your day-to-day tracking into clinical evidence your prescriber can actually use — without ever leaving the UK, and without ever being sold to anyone.
Engineer, veteran,
and a patient.
CannaLog is built by one person. No VC deck, no offshore call centre, no growth-hack team scraping health data to sell ads. Just an engineer with the background, the discipline, and the lived experience to do this properly.
The founder served in the UK armed forces before moving into technology — a decade-plus career in infrastructure engineering across some of the world's largest banks. Every design choice on this platform is filtered through the question: "would I trust this with my own health data?"
What we refuse to
compromise on.
Six non-negotiables of how CannaLog operates — not because they're trendy, but because they're right.
- A medical device or a substitute for your clinician.
- A marketplace — we don't sell cannabis or arrange prescriptions.
- An ad network — there is no tracking on the patient portal.
- A data broker — we never sell your personal or health data.
- Available to under-18s or to people without a UK prescription.
- A replacement for calling 999 in a medical emergency.
