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.

How was today? elou asks one question and keeps your answer as a single colored square. Over time the squares become a year you can read at a glance. ONE TAP A DAY Pick Good, Okay or Bad. That's it. If you want to say a little more, add a short note about what made the day feel that way. YOUR YEAR, IN COLOR Every day you log fills in a square on your year ribbon: sage for good, sand for okay, terracotta for bad. Swipe back to see earlier years, and see how many days you've logged in each one. LOOK BACK, GENTLY Tap any day to read what you wrote. Your most recent entries sit under Lately, so the last few days are always close by. MISSED A DAY? Tap its empty square and fill it in. You can edit any entry later, too. EVERY MOOD COUNTS The colors are earthy on purpose. A bad day isn't an error, and logging one counts as much as logging a good one. PRIVATE BY DESIGN Your entries stay on your iPhone. There's no account to create, nothing to sign in to, and no ads, analytics or tracking. elou never connects to the internet, so your notes are never sent anywhere.

Verdict
The clearest difference is in-app purchases: elou at none against DD's 3. DD's advantage is iOS requirement (17.6 vs 26.0). On price, ads and device support there is nothing between them.
