Close2 App vs TrailLink

Close2 helps people at the same event or place connect without turning the moment into a public feed. Use Close2 to see nearby presence, join private event rooms, view profiles, send messages and stay in control with block, report, privacy and account deletion tools. For event hosts, Close2 supports QR/code access, branded event spaces and public-room reporting while keeping direct messages private.
