1-10 is a real-time beauty rating and social engagement app that blends dynamic user interaction with gamified scoring and secure communication. It encourages meaningful profile discovery through ratings and gifts, while maintaining privacy, moderation, and fairness at every layer.
Built for a highly engaged social audience, the app transforms simple gestures—like rating a profile or sending a gift—into a deeper system of incentives, recognition, and communication. With secure real-time updates and strict anti-manipulation systems, it keeps interactions fun, fair, and rewarding.
To enable discovery, feedback, and connection at scale, the app offers:
- Profile-based beauty rating from 1 to 10 with real-time score updates
- Gender-based profile matching and rating eligibility
- Gift catalog that impacts user scores positively or negatively
- Dynamic leaderboards based on ratings and gifts
- Real-time chat unlock based on rating thresholds and purchases
- In-app purchases for gifts and premium features
- Cross-platform push notifications for gifts, ratings, and chat requests
- Moderation and fraud prevention to ensure safe user interactions
These features create an immersive platform where user attention translates into recognition, social value, and new connections—backed by a technically rigorous and scalable infrastructure.
