In addition, app users can sign up for notification alerts for when the HRS mobile services are in your region, financial incentives that are available at HRS, and spikes in overdoses or identification of harmful trends in the drug supply. Finally, we are continually updating the video library on the app to provide participants with information about how to administer naloxone, conduct drug checking, and medications that help to manage substance use.

Mode Zero is a calm, focused recovery tracker for people quitting anything: alcohol, nicotine, cannabis, drugs, sugar, caffeine, gambling, or any habit you're ready to leave behind. No pressure. No shame. No motivational spam. Just a clear picture of your clean time, your savings, and the real health your body is rebuilding - day by day. WHY MODE ZERO Most recovery apps shout. They flood you with reminders, push you to share streaks, and treat the work like a game. Mode Zero is the opposite. Calm focus. Real progress. Support without judgment. Built for adults who want a serious, beautifully designed companion through the hardest and most important work of their lives. QUIT ANYTHING Mode Zero adapts to whatever you're quitting: - Alcohol - Nicotine and vaping - Cannabis - Other drugs - Sugar and processed food - Caffeine - Gambling - Social media - Or any habit you define yourself Each one comes with its own recovery metrics, its own savings tracker, and its own milestone path. WHAT YOU GET Live Recovery Counter Watch your clean time grow down to the second. Days, hours, minutes — backed by your real start date and protected across time zones. Recovery Benefits See exactly what your body and mind are rebuilding. Attention span, sleep quality, melatonin release, dopamine baseline, social anxiety, circadian rhythm — each metric fills toward 100% as you stay clean. Real biology, not fake gamification. Savings Tracker Every clean day is time and money back in your life. Mode Zero shows you exactly how much you've saved since day one, and tracks it toward goals you actually care about. Daily Pledge A simple commitment each morning. A countdown that proves you kept it. A streak history you can look back on with pride. Personal Journal Capture the moments that matter — cravings you beat, decisions you made, why today was different. Your private record of the work. Achievement Milestones 1 day. 7 days. 30 days. 90 days. 1 year. 5 years. Beautiful, earned recognition at the points that count — including bonus content packs at key streaks. Daily Inspiration A thought of the day, curated quietly. Save the ones that resonate. Skip the ones that don't. No noise. Shareable Recovery Cards Optional, milestone-based, and beautifully designed. Share your progress on your own terms — your clean time, your health gains, your story. Calm Notifications We don't push you every day. We show up at the milestones that matter and stay out of your way the rest of the time. Compassionate Protocol If you slip, we don't dramatize it. Your streak resets cleanly, your metrics decay slightly, not fully, and you move forward. No shame. No starting from zero. WHO THIS IS FOR Mode Zero is built for adults quitting any substance, behavior, or habit who want a serious tool - not a cheerleader. If you're motivated by clarity, long-term health, and seeing measurable progress instead of being told you're crushing it, this is for you. PRIVACY FIRST Your recovery data is yours.
