Grams Left is a free stock and consumption tracker for UK medical cannabis patients. It answers one question: what do I actually have left?
Why This Exists
If you have a prescription, you probably recognise the problem. A package arrives with a known weight. You use it over days or weeks. Between different strains, different consumption methods, and the general busyness of life, the running total gets fuzzy fast.
Some people keep spreadsheets. Some keep notes. Some just eyeball the packaging and hope for the best. There had to be something simpler.
Grams Left keeps your stock, consumption, and estimated balance in one place — updated with every entry. No maths, no guesswork, no forgetting whether you logged Tuesday's dose.
What Grams Left Does
- Set what you have. Add each product with its weight and strain name — exactly as it arrived.
- Log what you use. Tap a method (vape, oil, flower), enter the amount. Takes seconds.
- See your estimated balance. Your balance updates with every entry, so you always know roughly where you stand.
- Prescription countdown. See how many days until your next estimated prescription date.
- Burn rate and trends. Understand your average daily consumption and spot patterns over time.
Free vs Plus
The core tracker is free forever — no card required. You can track up to 3 active products, archive old ones, and add new ones without losing your history. For patients managing more products or wanting deeper tracking, Grams Left Plus unlocks unlimited active products, per-product history and stats, restock tracking, and early access to new features. Plus is £2/month or £20/year.
Founding users get 60 days of Plus free. No catch — just a thank-you for being here early.
Privacy Built In
Your tracker records are yours. We do not sell, share, or broker your cannabis, prescription, strain, or consumption data to anyone — not clinics, pharmacies, advertisers, insurers, employers, or data brokers. You can export your data or delete your account at any time.
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.
What Is Next
Grams Left launched with the core tracker and the features above. We are working on more — things like better product rotation, personal summaries, and tools that make tracking feel even lighter. If there is something you wish the app did, let us know.
The best way to stay updated is to check this blog. We will post about new features, security updates, and the occasional look behind the scenes of building a medical cannabis tool.
Thanks for reading — and happy tracking.
