Everything you need to track
You have a prescription. You receive your medication. Then what? Grams Left gives you three things every medical cannabis patient needs.
Stock balance
Your estimated remaining balance updates with every dose you log. Set what you have once, then just log as you go.
Burn rate
See how quickly you are using your prescription. Grams Left calculates your average daily consumption so you can spot trends.
Prescription countdown
A visual countdown shows how long your supply will last. Know whether you will make it to your next prescription date.
Start in under a minute
Set your stock
Enter how many grams you have. That is your starting balance.
Log each dose
Tap your method, enter the amount. Your balance updates. It takes seconds.
Check your countdown
Your estimated balance, burn rate, and prescription countdown are always up to date. No more guessing.
Why patients choose Grams Left over spreadsheets
Spreadsheets can do anything, but they are not built for quick logging on your phone. Missing a dose entry breaks your totals. Adding weekly consumption means manual selection. And nothing warns you when you are running low.
Grams Left was designed for the single purpose of cannabis stock tracking. It does not try to be a clinic portal, a marketplace, or a social network. It is your tracker — clean, private, and always showing you what you have left.
Private by design
Your tracker records are not sold. No cannabis data sent to analytics.
Works on your phone
Install to your home screen. Log doses offline. No app store needed.
