Petals: Cannabis Use Tracker

Weed tracker to quit, cut down or understand your cannabis use. Open source.
新版本 3.43.4
The button on the home screen widget works now. Adding a copy of your last use from the widget silently did nothing before.
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

Petals is free and licensed under the AGPL-3.0. The full source code is public, contributions are welcome, and the app is translated by its own community of users.

  • 新版本 3.43.1
    The app's colours are easier on the eyes. The bright green on dark backgrounds has been toned down, the pink accents are no longer washed out, and text that was hard to read has been fixed, including the hit timer countdown that was nearly invisible in light mode.
