Track your cannabis use, no judgment
JointTracker is a free cannabis tracker: log sessions solo or with friends, take them on in the leaderboard and keep tabs on tolerance breaks, stash and spending. Works offline, too.
Want it as an app on your phone? On iPhone/Safari: tap Share → "Add to Home Screen". On Android/Chrome, if you don't see the button above, open /app and use "Install app" in Settings.

Why use a cannabis tracker
Keeping a log shows you your real habits, not the ones you think you have: how many sessions a day, at what times, and how much you spend each month. JointTracker is built to be honest and judgment-free, whether you just want to keep an eye on things or you're planning a tolerance break or cutting down.
It's a Progressive Web App (PWA): it goes on your home screen like a native app, but there's no app store and no manual updates, and it works offline too.
