How Well Do You Know Me? CocoG positions itself as a digital icebreaker and relationship evaluation tool, transforming personal knowledge into an engaging game format. Developed by fenol s.r.o., the iOS application leverages question-based gameplay to measure how well participants understand each other's preferences, memories, and personality traits. The application's core functionality revolves around customizable question sets spanning multiple categories including personal preferences, habits, shared memories, and quirky personality aspects. One player secretly answers questions about themselves while other participants attempt to guess these responses. The system then calculates accuracy scores, providing quantitative feedback on relationship depth. Questions range from lighthearted topics like food preferences to more thoughtful inquiries about life values and past experiences. User experience benefits from a clean, intuitive interface with straightforward game setup and smooth progression between questions. The color-coded scoring system immediately visualizes alignment between answers, while the category selection allows groups to tailor gameplay to their comfort level. Real-world usage typically occurs in social gatherings, date nights, or family events where participants already share some level of familiarity, though the app can also serve as an acquaintance-building tool in newer relationships. With no user reviews currently available, the application's 4.49/5 App Store rating suggests generally positive reception, though the absence of detailed feedback makes specific user sentiment difficult to ascertain. The high rating indicates satisfactory performance regarding stability, engagement value, and meeting user expectations for social gaming applications. The application excels at facilitating meaningful conversations and revealing unexpected knowledge gaps in relationships, though its effectiveness depends heavily on participant honesty and existing relationship depth. Limited question customization and potential repetition after extended use represent notable constraints. Ideal for small social groups seeking interactive entertainment with genuine interpersonal discovery components.
