Log accurately
Capture substance, dose, route, timing, notes, and context in one timeline so your history is complete and searchable.
What Freaklog helps you do
See patterns over time
Review your own entries to identify habits, frequency changes, and trends that are hard to spot from memory alone.
Reduce avoidable risk
Use intake limits and reminders to set boundaries before a situation becomes unclear or impulsive.
Keep control of your data
The app is designed to work fully offline; your journal data remains local unless you explicitly use network-based features.

Built with harm reduction in mind
- ✓Structured journaling reduces guesswork about what happened and when.
- ✓Substance information references PsychonautWiki with additional data from TripSit and saferparty.ch.
- ✓You can keep detailed history while still deciding exactly what, when, and where to share.
Important: Freaklog is a self-tracking tool, not medical advice. In emergencies, contact local emergency services immediately.
