Track your symptoms. Log your sessions. Understand your patterns. DD-420 gives veterans real insights — private, on-device, and always free.
DD420 is a private wellness companion for veterans managing PTSD who also use cannabis for symptom relief. No judgment. No politics. Just tools.
Your data never leaves your device. No accounts. No ads. No one is watching.
DAILY CHECK-IN
Track your PTSD symptoms using the same four clusters the VA uses — Intrusion, Avoidance, Mood & Thinking, and Alertness — in a guided, one-step-at-a-time flow built to feel less overwhelming. Rate each area honestly, log your mood and sleep, and note what triggered you. Takes less than two minutes, and your progress saves automatically if you get interrupted.
Over time, your check-ins build a picture of how you're actually doing — not how you think you're doing.
CANNABIS SESSION LOG
Log each session with strain, method, THC and CBD content, timing, and — most importantly — why you used it and whether it helped. Select from 12 veteran-specific conditions including PTSD symptoms, chronic pain, sleep and insomnia, nightmares, anxiety, hyperarousal, and more.
Each condition has its own curated list of effects to track. You'll start to see which strains, methods, and dosages actually move the needle for your specific symptoms.
INSIGHTS
Charts built from your own data. See your symptom severity trend over time, which PTSD clusters affect you most, how sleep quality relates to your symptom scores, how cannabis use correlates with next-day symptoms, and which conditions you use most.
The more you log, the clearer the patterns become.
COPING TOOLS
Evidence-based tools organized by what you need right now. Breathing exercises, grounding techniques, progressive muscle relaxation, sleep visualization, and urge surfing — available any time, no subscription required.
TOLERANCE BREAK TRACKER
Set a break goal, track your progress day by day, and get coping prompts for cravings. Includes plain-language education on what tolerance is and what to expect during a break.
100% FREE
Every feature in DD420 is free. Always. No subscriptions, no locked features, no paywalls. If you want to support development, an optional one-time tip ("Buy Me a Bag") is available in Settings — never required.

DD-420 — Version 2.5
What's New (paste into App Store Connect → "What's New in This Version"):
• Crisis Bar now offers Breathe Now and Ground Me Now — fast, one-tap access
to a guided breathing or grounding session, right alongside 988, text, and
chat. Help and calm are both one tap away.
• Emergency Info Card can now include what helps you calm down, your safe
place, and what not to do or say — three optional fields that only show up
in your shared card if you fill them in.
• Cannabis logging adds three more side effects to track: Panic, Anger /
irritability, and Felt unsafe.
• PDF reports can now include your own Provider Notes — what you want your
provider to know, and questions you want to ask — shown only if you write
something.
• First-time setup is shorter — cut from 14 screens down to 4. Same privacy,
safety, and crisis-line information, a lot less clicking to get through it.
• The product scanner's review screen is simpler — fewer fields to
double-check against your package before saving.
• Fixed two scanner bugs: a strain name could get mislabeled with the wrong
text from the package, and a Total Terpenes reading could be missed
depending on how the label printed it.
