Know what you have left.
A free stock and consumption tracker for UK medical cannabis patients who are tired of guessing what they have left.

Built because I needed it too.
Grams Left was created by a UK medical cannabis patient for other patients who want a clearer way to track their stock.
It started from a simple problem: knowing what arrived is easy, but knowing what you actually have left gets messy fast.
When you rotate between products, log manually, or try to remember what you used last week, the running total gets messy fast. Grams Left keeps that record in one place.
Three steps.
Add what you have
Set your starting amount. The tracker holds your estimated total.
Log what you use
Tap a method, enter the amount. Log straight away or catch up once a day.
See your estimated balance
Your estimated remaining balance updates with every entry.
Not a clinic portal. Not a marketplace. Just your tracker.
Some tools are built to become full medical cannabis workspaces. Grams Left is deliberately simpler — for the everyday tracking problem.
Free tracker. Premium trial for founding users.
The core tracker is free forever and does not require a card. The first 100 users can try Plus for 60 days, then keep it only if it earns its place.

Built to track your stock, not profile you.
Your tracker records are yours. Grams Left does not provide a product dashboard for browsing individual strain names, dose amounts, prescriptions, or notes. Operational access is limited to running, securing, and supporting the service.
We do not sell, share, or broker your cannabis, prescription, consumption, strain/product, or account data to clinics, pharmacies, advertisers, insurers, employers, or data brokers. You can export your own data from Settings or delete it from the active app.
Essential cookies keep sign-in and age checks working. Optional analytics is only used after consent, and tracker records are not sent to analytics. Product measurement is limited to broad usage signals, such as which pages are working. Launch milestones use rounded, aggregated totals, not individual records.
Plus is £2/month because we would rather charge a small, clear subscription for deeper features than pretend the app is free while monetising patient data somewhere else.
Privacy-first
No sale of your records. No tracker data sent to analytics.

Questions you might have.
Is Grams Left legal?
Grams Left is personal record-keeping software. It does not sell, supply, prescribe, dispense, recommend, or advertise cannabis products.
Does it tell me how much cannabis to use?
No. Grams Left records what you enter. It does not provide dosing guidance, treatment advice, or medical recommendations.
Are the balances exact?
No. They are running estimates, not a measurement of what is physically in your packaging. Grams Left subtracts what you log from the amounts you enter, so missed logs, typos or unrecorded changes will affect the figure. Use it as a guide and check your physical stock when the exact amount matters.
Is this a data collection exercise?
I built Grams Left with user privacy in mind. The details of your strains and consumption stay private to your account, with only the service processors needed to run the app. Tracker records are used to calculate your stock and usage, keep your account working, and support essential security or service functions. We do not sell them, broker them, use them for ad targeting, or share them with clinics, pharmacies, advertisers, insurers, employers or data brokers. Optional analytics is helpful for us and, as the name says, optional; it does not include strain names, dose amounts, prescriptions or notes. You can export your data or delete it from the active app whenever you want.
What do founding users get?
The first 100 users of Grams Left get 60 days of Premium for free. Premium signup goes through Stripe; cancel the trial before it ends and you will not be charged. The free version does not require a payment card to use. Your payment details are stored securely with Stripe, never on Grams Left.
Who runs Grams Left?
Grams Left was created by Tyler Casey, formerly known as Tyler Green, who has been a medical cannabis patient for three years, and spent 16+ years working in this industry and interviewing pioneer medical cannabis consumers. During that time Tyler has run out of stock many times - but not anymore! Grams Left was built for personal use, then expanded into the web app you see today.
