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. BUILT FOR VETERANS Veterans Crisis Line: 988, press 1 — call or text directly from the app, one tap, any time. Chat: veteranscrisisline.net DD420 is not affiliated with the VA or DoD. It is not a medical app and does not diagnose or treat any condition. All data is stored on your device only.

Verdict
The clearest difference is monetization model: DD at free against The Training Notebook One's free with in-app purchases. DD also leads on ratings volume (13 vs 2). The Training Notebook One's advantage is update cadence (daily vs every 3 days) and device support (3 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. DD sells 3 one-off in-app purchases and The Training Notebook One sells 6 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
