You've tried quitting before. Deleted everything, swore it was the last time — and a week later you were back where you started, wondering why willpower alone never works. It's not a willpower problem. It's a brain-wiring problem. And wiring can be changed. Solido gives you a structured, neuroscience-based path to break free from lust and compulsive habits for good: a personalized 90-day reboot plan, emergency support the moment an urge hits, and honest tracking so you can see your brain recovering week by week. WHY Solido WORKS PERSONALIZED RECOVERY PLAN Answer 12 questions about your habits, triggers, and goals. Get an honest read on your dependency level, a realistic recovery timeline, and a custom 90-day plan — including when to expect improvements in focus, energy, mental clarity, and self-control. PANIC MODE — HELP WHEN THE URGE HITS This is the moment that decides everything. Activate Panic Mode for a 4-step crisis protocol: guided breathing to calm your nervous system, the cold-water reflex to cut the urge, movement to disrupt the craving loop, and grounding techniques to get you back in control. AI RECOVERY COACH, 24/7 Urges don't keep office hours. Talk to a judgment-free AI coach trained for addiction recovery — any time, in multiple languages. Get help managing urges, preventing relapse, and staying motivated when it's hardest. REAL-TIME STREAK TRACKING A live counter of your streak in days, hours, minutes, and seconds. Personal bests, total clean days, and monthly comparisons — proof of progress you can look at when motivation dips. RECOVERY ANALYTICS See your patterns clearly: weekly urge-intensity charts, time-of-day relapse analysis, a monthly recovery calendar, withdrawal tracking, and dopamine-reset progress. When you know your danger hours, you can plan around them. PRIVATE JOURNAL Log mood, urges, and triggers. Over time, your entries reveal the root causes behind the habit — so you can fix the cause, not just fight the symptom. Stored on your device. CHALLENGES THAT BUILD DISCIPLINE 21-Day Habit Reset, weekly check-ins, and a Target Quit Date countdown to keep you accountable and moving. ANONYMOUS COMMUNITY You're not doing this alone. Share wins, get support during hard moments, and encourage others on the same path — completely anonymously. BUILT FOR PRIVACY This is a sensitive journey, and we treat it that way. Anonymous sign-in, local data storage, encrypted chat. No real name required, ever. SUBSCRIPTION Solido requires an active subscription: $4.99/month or $14.99/year for unlimited AI coaching, Panic Mode, recovery analytics, and community access. Payment is charged to your iTunes account at confirmation. Auto-renews unless turned off at least 24 hours before the period ends. Manage in Account Settings. Download Solido and start your reboot today. The best day to quit was yesterday. The second best is right now.
