Goals with accountability - not performance. Duovoco is a focused app for people who want to build something consistent without the noise. No streaks-shaming, no leaderboards, no infinite scroll. Just check-ins, a few people who care, and a reflection partner that actually listens. THREE LAYERS, ONE APP Personal - Your AI Buddy A reflection partner that remembers your goals, your patterns, and how you actually feel. It notices when something shifts. It nudges, gently. It listens without trying to fix. Circle - Your Buddies A handful of people you trust to see what you're working on. They react with Voco (acknowledgment), Lift (encouragement), or Spark (insight). No likes, no metrics. Just presence. Club - Your Groups Shared goals, group templates, weekly check-ins together. Built for small accountability circles - recovery, fitness, focus, learning. Public or invite-only. WHAT MAKES IT DIFFERENT - Check-ins designed for momentum, not perfection. Micro (one tap) for hard days. Standard for the rest. Both count. - Streak protection. Miss a day? Freeze it, don't lose it. Three freezes a week on Pro. - Goal topics with thoughtful defaults: fitness, quit, sleep, focus, mindfulness, money, learning, health, social, creative. - Public, Buddies-only, or Private — per goal, your choice. - Mood and energy tracking woven in. The Dashboard surfaces patterns you wouldn't notice on your own. - Recovery and quit-niche aware. The AI knows when to step back instead of pushing forward. - Crisis-aware safety. If something serious comes up, the AI doesn't pretend to be a therapist. It points you somewhere real. PRICING Free tier covers the basics: 3 goals, 3 groups, 1 streak freeze per week, limited AI. Pro unlocks unlimited goals, 10 groups, private groups, 3 freezes weekly, full AI access, weekly reflection, and advanced dashboard. - Monthly $11.99 - Yearly $87.99 (save 39%) - Lifetime $219 DESIGNED FOR THE LONG GAME Duovoco is not built to be addictive. There is no infinite scroll, no algorithmic feed, no streak that you have to defend at 11:58 PM. The whole point is that you show up because you decided to, not because the app made you panic. Presence over performance. Consistency over perfection.
