The actual Grams Left dashboard
A real view of the private tracker you use to keep stock, consumption, and your estimated balance together, shown with example data.
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.
Private tracking for your own record keeping
Prescription tracking
Keep your own prescription arrivals, stock, and estimated use in one private tracker. Grams Left does not provide clinical advice.
Personal tracking
Keep a private personal record of what you have and what you log, without a marketplace, public feed, or product recommendations.
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. Takes seconds.
See your estimated balance
Your estimated remaining balance updates with every entry.
Join 83+ patients tracking their prescriptions.
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 does the job. Plus goes further.

Your records stay yours.
Your tracker records are yours. Grams Left does 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 your account. Essential cookies keep sign-in working. Optional analytics is only used after consent, and tracker records are not sent to analytics.
We do not need to know what strains people have or how much anyone uses. 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 £4/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. Users are responsible for using it only where lawful.
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 my data sold?
No. Your tracker records are yours: cannabis, prescription, strain/product and consumption data are not sold, brokered or used for ad targeting. You can export your own data from Settings or delete your account. Optional analytics only tells us broad product usage after consent. It does not include your strains, dose amounts, prescriptions or notes.
