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.

About

Ghost Go Run

Features
Read full description

Race against a real benchmark, from you or a friend. Ghost turns a previous activity into a live reference, so you can see whether you are ahead or behind while you run. Choose a distance and pace goal or a ghost, start moving, and let the gap guide you. DURING EVERY ACTIVITY • Choose a distance and pace goal, or challenge a saved activity. • Check your gap and progress on iPhone. • Use Apple Watch to start, pause, and finish without reaching for your phone. • Hear spoken updates during the activity, including each kilometre split. • Check time, distance, pace, heart rate, and elevation when available. AFTER YOU FINISH • See the result at a comparable distance. • Review your activity history and saved references. • Discover records, trophies, and milestones earned from eligible activities. • Share your ghost through your usual apps so someone else can challenge it in Ghost. LOCAL PRIVACY Ghost does not require an account or a server. Your activities, settings, and library are stored on your device. The app uses GPS to measure the activity, motion data to help interpret the session, and HealthKit to read available fitness metrics; Apple Watch records the workout when you start from the watch. Audio is used for activity guidance. Ghost does not sell your data and has no ads. Sharing a ghost is optional: the file is sent through the app you choose and is handled according to that app’s policies. Ghost is a fitness tool. It does not provide medical diagnosis or treatment.
