프루프, a private dating app, implements a 'Social Proof' psychology approach to validate decent individuals. Unlike other dating apps, it assesses unique qualities and potentials of members based on evaluations from existing users. Users can verify the authenticity of individuals through matching reviews on 'real-life' and 'conversation manners.'

Joining 프루프 involves two methods: evaluating attractiveness scores anonymously by existing members or submitting documents for instant approval regardless of profile evaluations. Users can directly evaluate new members' attractiveness, impacting their approval status, and provide feedback on manners through matching reviews.

Feel secure using 프루프 as it ensures no fake or stolen profiles, allowing users to block contacts they know. Even if not approved initially, users can request up to five reevaluations per month. The app also offers the option to go dormant and hide profiles, ensuring a hassle-free dating experience.
