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.

The most beautiful functional-fitness timer — and the most dependable. Now on iPad, and on your wrist. Squall is the WOD timer that gets out of your way: readable across the gym, it never hijacks your music, and it never fires a cue while you're paused. Set it up in seconds and trust it completely. Now native on iPad — the same timer, full-screen, with a big landscape gym clock you can read from across the room. EARN YOUR TROPHIES — ACHIEVEMENTS Every session now earns badges — free, and all on your device. Chase 22 across milestones, personal records, streaks, grit, and variety, each climbing a bronze-to-diamond ladder with live progress. Unlock one and a 3D metal shield spins up against a stormy sky — then share it as a card or a short storm video. Tap the trophy in your Log any time. RUN IT FROM YOUR APPLE WATCH Leave your phone in the cubby and run a full workout from your wrist — AMRAP, For Time, EMOM, or Tabata, tuned with the Digital Crown. Haptic and audio cues, a complication to launch straight in, and it all syncs back automatically. HEART RATE & CALORIES, IN APPLE HEALTH Squall saves every session to Apple Health — free. With Apple Watch and Pro, a live session records real heart rate (min / avg / max) and active energy on your results and log. No Watch? It estimates calories from your work, sharpened by an optional weight in Settings. EVERY TIMER YOU TRAIN WITH • AMRAP — as many rounds as possible, with tap-to-log round counting • For Time — count up with an optional cap and lap splits • EMOM — every minute on the minute, including alternating stations • Tabata — classic 20/10 ×8, fully editable with sets and rest • Mix (Pro) — chain any stages of any type into one seamless workout, with a live total and a clear "NEXT UP" YOUR MUSIC STAYS YOURS Squall ducks your audio for a cue, then restores it. Keep Spotify, Apple Music, or a podcast playing the whole session. CUES THAT NEVER LIE Pause and every sound stops — no phantom beeps. Cues are scheduled for sample-accurate timing and keep firing with the screen locked. Beeps, voice cues, or both, with haptics you'll feel anywhere. COACH VOICES Use any installed iOS voice, or Squall's coaches — Ivy and Jon free; Hope, Mark, Elariel, and Jofra with Pro. BUILT TO BE GLANCEABLE Pick a running-screen face: a depleting radial ring, bold stacked numerals, or the split-flap Flipboard — all free. Go Pro for Retro Digital (amber LCD) and Pride. The whole screen shifts color by phase, on iPhone or iPad. LOCK SCREEN & DYNAMIC ISLAND (Pro) A branded Live Activity keeps your time remaining ticking on the Lock Screen and Dynamic Island — rock-solid even when locked. HANDS-FREE & ACCESSIBLE Control it with Siri — "Start Squall." Full VoiceOver, Dynamic Type, and Reduce Motion throughout. NO ACCOUNT, EVER No sign-up, no login — Squall works fully offline, and your workouts and logs stay on your device. SQUALL PRO Go ad-free and unlock Mix, premium clock faces, unlimited saved workouts, premium coach voices, the Lock Screen / Dynamic Island Live Activity, and heart-rate & calorie tracking on Apple Watch. Monthly, annual (7-day free trial), or a one-time lifetime purchase. The free tier is a genuinely great timer — no nags during a workout. The calm before the storm. Hit GO and the storm breaks. —————————————— SQUALL PRO — SUBSCRIPTION DETAILS • Squall Pro — Monthly: auto-renewing, $2.99/month • Squall Pro — Annual: auto-renewing, $19.99/year, with a 7-day free trial • Squall Pro — Lifetime: one-time purchase, $39.99 Payment is charged to your Apple ID at confirmation.

Verdict
The clearest difference is ads: DD at none against Squall's shown. DD also leads on monetization model (free vs free with in-app purchases) and update cadence (every 4 days vs every 2 weeks). Squall's advantage is device support (3 vs 1). On price, rating, review sentiment and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. DD sells 3 one-off in-app purchases and Squall sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for DD against 5.0 for Squall. That said, the two scores are not equally well evidenced: DD has 14 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
DD ships an update every 4 days, Squall every 2 weeks. The most recent releases landed on October 28, 2026 and October 18, 2026 respectively.
