Petals: Cannabis Use Tracker

Weed tracker to quit, cut down or understand your cannabis use. Open source.
新版本 3.47.0
New: rate each use from half a star to five stars, right in the use form. The use card shows its stars, and each strain in Settings, Strains now shows how many times you used it, the grams, the spending and its average rating. Backups carry each use's rating. The hour of day chart in Stats can now show a point every 15 minutes. The use form now fits above the keyboard, and scrolling it from the date or time no longer opens their pickers.
Petals is a free and open source cannabis tracker that helps you understand your habit — and change it at your own pace.

Whether you want to quit weed, take a tolerance break, cut down gradually, or simply know how much you actually use, Petals gives you the numbers. No account, no sign-up, and your data never leaves your phone.

TRACK YOUR USE

- Log every session: amount in grams, cost per gram, date and time
- Record the consumption method: smoked, vaporized, edible or other
- See the time since your last use, down to the second
- Track how much you spend on weed, today, this week and overall
- Add a use in one tap from the home screen widget

UNDERSTAND YOUR PATTERNS

- Statistics and graphs of your cannabis usage over time
- Usage by hour of day and by day of week, so you can see when the urge really hits
- Filter your history and spot the trends you would never notice from memory
- Watch the real cost of the habit add up

CUT DOWN AT YOUR OWN PACE

- Time-gate your sessions: set a minimum interval between uses and let the timer hold you to it
- Register pause periods for a tolerance break or a full stop
- No streak shaming, no pressure: the app shows you the data, you set the pace

WITHDRAWAL AND DRUG TESTS

- Track withdrawal symptoms over time: irritability, anger, restlessness, sleep difficulty, anxiety, decreased appetite and discomfort
- Estimated THC concentration after your last use
- Estimates of when urine, blood, saliva and hair tests may come back clean, with the sources cited

PRIVACY BY DESIGN

- All of your data stays on your device
- No account, no cloud, no analytics
- Lock the app behind a personal PIN
- Export and import everything as plain CSV files — your data belongs to you

HARM REDUCTION

- Built-in harm reduction information, because using less safely beats using blindly

FREE AND OPEN SOURCE

  • 新版本 3.46.0
    New: strains. Keep a list of the strains you use, with optional THC, CBD and cost per gram. Pick one when you log a use: its cost fills in, the use card shows it, and the filter finds uses by strain. Manage them in Settings, Strains. Backups carry each use's strain. Importing a backup whose notes have a line break works now, and Petals tells you how many uses an import brought in, or that the file couldn't be imported.

  • 新版本 3.45.0
    New: a duplicate button on every use. It opens the form with the amount, cost, notes and method already filled in and the date set to now, so logging a strain you had before means no retyping. The notes on each use can now be selected and copied too.
