Real-Time Level Tracking

Pharmacokinetic modeling on a 0–11 scale through onset, peak, and decay. Route-specific absorption (oral, nasal, IV, sublingual). Multi-substance stacking with tolerance-adjusted calculations.

Session Timeline

Tap your level to see a live chart of your intoxication over time. Dose markers, peak tracking, current level indicator, and a full dose log for the session.

Interaction Warnings

Automatic detection of dangerous combinations: serotonin syndrome, respiratory depression, lethal GHB+alcohol, and more. Color-coded severity levels: Info, Caution, Warning, and Danger.

Learn & Educate

Browse 22 substances by category. Deep-dive into pharmacology, timing, dosing, risks, safer use, and drug checking resources. Harm reduction essentials at the top.

Emergency SOS

Two modes: “I need help” (breathing exercises, grounding, trusted contact call) and “Someone else needs help” (GCS calculator, overdose checklist). Calm mode softens visuals during distress.

Care & Aftercare

In-session tips, 7-day recovery support with substance-specific normalization, timed aftercare hints, and daily wellbeing check-ins tracking mood, energy, and sleep.

Nasal Line Guide

Visual line size reference for nasal substances. Uses bulk density per substance for accurate light, common, and strong line lengths. Safer snorting tips included.

Calm Mode

Trip-safe UI toggle: softens reds to ambers, mutes pulsing animations, and uses supportive language. Danger warnings remain at full intensity. Activates across the entire app.

GHB/GBL Safe Redose Timer

2-hour countdown timer that locks until it’s safe to redose GHB or GBL. Prevents the most common cause of GHB overdose.

Drug Combo Matrix

Interactive TripSit-style safety matrix for all tracked substances including SSRIs and MAOIs. Seven color-coded risk levels with detailed explanations.
