What's new v3.46.0
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.
About Petals: Cannabis Use Tracker
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
