Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 10.62 MB, so it installs quickly even on modest connections.
This build is signed by "Leonardo Colman Lopes" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

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
